2007 Arctic Cat Jaguar Z1 Next Generation Performance 4-Stroke

Most of the time when we tell you “all new” it’s more a matter of mostly new. Well, this time around about the only thing that isn’t all new is maybe the track. From the skis to the chassis to the engine to the rear suspension, the 2007 Arctic Cat Jaguar Z1 is about as “all new” as you’re going to find.
Starting with the Twin Spar chassis, we find Arctic Cat’s torsionally rigid chassis to mount next-generation suspensions to. The rigid chassis itself is reason to get very excited, as the difference this makes in suspension performance is very noticeable and should also greatly improve chassis durability. Much of this comes from the use of self-piercing rivets instead of welding the aluminum. Arctic Cat claims the chassis will be just as strong after 8,000 miles as the day it left the factory, a hefty claim, indeed.
Just as important is the rider-forward ergonomics this new platform provides. The seating position of the Twin Spar chassis places the rider with a 90-degree bend in their knees, something Arctic Cat reps were adamant about. They firmly believe this is a better riding position than the REV offers, especially at the knee joint.
Also new is Arctic Cat’s IRP (Infinite Rider Positioning) system; an adjustable seat, handlebars and footrests. The seat has seven adjustment positions, moving about a half inch forward and a 1/3 inch vertically with each of the seven positions. This amounts to a total of 3.66” forward and 2.41” vertical movement range. A thick (7.17”) of seat foam enhances the comfort with a forward slant to keep you in the cockpit. A cam lever at the rear of the seat lets you unlock, adjust and re-lock the seat with one hand.
The adjustable handlebars are really unique. A single locking lever top and center lets you move the bars fore and aft as well as being able to rotate the controls. A total of 3.32” forward and 2.11” vertical movement can be made, with a handlebar rotation of 85 degrees. The footrests can also be set to one of three positions, allowing the Jaguar Z1 to comfortably fit a wide range of rider sizes and styles. Also, a riser block can be installed to raise the bars even more, as the cables and wiring is said to be long enough to allow some further personalizing.

The Jaguar Z1 is powered by an all-new compact 1056cc twin-cylinder 4-stroke. This high-compression fuel-injected engine features four valves per cylinder and has a power delivery more like a two-stroke; it builds with the engine RPMs, for Arctic Cat-like acceleration.
An O2 sensor and feedback system provides phenomenal economy, making this the cleanest Arctic Cat, ever.
Several unique technologies make their debut on this engine; Arctic Cat’s patented anti-engine braking takes away the harsh compression braking found on other four-strokes, giving the Jaguar a feel more like a two-stroke when you release the throttle. The Z1′s exhaust cam has a patented automatic de-compression system, so turning over the big bore twin is easier on cold mornings.
A breather system on the Z1 oil tank keeps oil in the tank and out of the engine compartment if the machine is tipped on its side, and a low oil pressure shut down system will shut the big twin down if oil pressure becomes too low, a safeguard to enhance durability.
Motor mounts are focused at the engine’s center of gravity, providing smooth operation despite the big twin architecture.  Stainless steel exhaust system resists corrosion and keeps the system looking good for years.

An adjustable height windshield offers five positions, from low and fast to tall and wind blocking. Total movement is in an arc with 3.55” of forward and 1.1” of vertical movement. All you do is unscrew the locks on each side, reposition the windshield and re-lock it.
Up front we find the seventh generation AWS front suspension. A CNC-machined front sub frame provides a strong mount, a key piece to making the Twin Spar chassis very rigid due to the lack of welds. Forged spindles and shock towers also increase the  strength and rigidity of the front end and reduce the weight. The upper a-arm returns to a more traditional design with the shock inside the “A”, unlike the Firecat’s AWS-6. The turning radius is back to where it should be, and steering effort is light due to a progressive steering ratio that uses a solid roller bearing on the steering post.
In the rear of the sled we find the “Slide Action Rear Suspension”. This novel approach to suspension coupling comes from the 440 SnoPro race sleds. Rather than solid mount the upper mount of the front torque arm, a U-shaped slot allows some movement within a slot at this location. This allows you to maintain full front arm travel while controlling weight transfer under acceleration to help keep the skis on the ground for improved cornering and acceleration. The Slide Action reduces harshness by allowing a softer transition during coupling, instead of a definite crossover point from uncoupled to fully coupled. The slot allows the whole suspension to shift rearward when coupling, which provides an added anti-squat feature as well during acceleration.
Bottom line, your skis stay on the ground more often which means better steering response and handling across the board. Big-bump G-outs are less frequent, yet small chatter ride quality remains intact. The sled squats less when you gun it, and track tension is more consistent through the range of suspension travel. Getting the skid frame in and out of the sled is also easier. And finally, changes in rider weight are not as big of a deal with this arrangement, the suspension is more forgiving.
One long awaited feature is push-button electronic reverse. The Jaguar is fitted with the ACT Diamond Drive gearcase, and for 2007 the system has been enhanced with an electronically actuated mechanical reverse. The rider pushes a button under the throttle on the right-hand block and the system pops an actuator that locks a planetary gear for fast and positive reverse engagement. It is quick, smooth and always works; no engine stalling like is common with the reverse-rotation systems found on some 2-strokes. Yes, it weighs a bit more, but it works well.
Other technology in the drive train includes a four-tower primary with four flyweights, great for getting the extra torque of the 1056cc twin through the belt and into the gearbox. A 10.5” secondary clutch offers a lower ratio and provide a smooth low-speed take off while increasing high speed consistency with reduced belt slippage. A non-threaded belt adjuster aids in quicker belt fit and deflection.
How ’bout that snow-specific motor? This two-cylinder dry-sump 4-stroke fitted with EFI is built for one thing – snowmobiles. No compromises here, but it does cost more. It fits down into the chassis much like a Firecat engine, for a low center of gravity and centered mass. This greatly masks the extra weight of the extra hardware of a 4-stroke.
Quoted output is a stout 125 HP through the 1100 (1056cc), yet it is said to be cleaner than the T-660 engine! Cat engineers wanted the narrow, laydown parallel twin to have a power delivery more like the 2-strokes they were used to, so the torque curve increases through the RPM range instead of being as flat as most 4-strokes. This was to provide a “feel” of acceleration more like a 2-stroke. Engine compression braking is all but gone via a patented anti-engine braking system.

Ride Impressions
Wow. We didn’t fully realize the difference a rigid chassis could make. The Jaguar is noticeably heavier than say a Firecat, but the difference in ride quality and handling is most impressive. The rear suspension soaks up the bumps better than most anything, dare we say approaching an M-10 in comfort but more capable across a wider range of conditions. The skis stay planted, the thing rails flat, and the overall perception is nothing but solid. The engine feels to be right there with a Yamaha RS Vector, and the power really does build instead of the flatter torque from the Vector. Cat engineers wanted a 4-stroke trail sled that felt more like an Arctic Cat. In this, they succeeded.
Less mass seems to be in front of you with the engine where it is. The sound of the engine isn’t as pleasing as a Yamaha 3 or 4-banger, but it’s not as industrial as a Polaris FST either.

Overall we’ve been nothing but surprised by how the Jaguar Z1s have worked for us. We’re not crazy about the styling, but as you ride it you realize it is truly better by design. We scoffed at the adjustable seat at first, then tried it in all positions as the conditions varied. Low and back for flat running, high and forward through the bumps does make a difference.
The 2007 Arctic Cat Jaguar Z1 is available in three colors; Black, Green or Red and retails for $10,499.

 

2007 Yamaha Phazer Mountain Lite – One Naughty Little Mountain Sled


Back in 1984 the first Phazer captivated the snowmobling world’s imagination with its innovative styling. Now, 23 years later, Yamaha is going to screw up everyone’s stereotypes and impressions of what a mountain sled should look like, what it should cost and, gulp, how light a four-stroke snowmobile really can be.
As mighty and as powerful as the RX-1 and now the Apex 4-strokes are, they are heavy sleds. Now here we have a 4-stroke mountain sled that claims a dry weight of under 500 pounds. Seriously. Yamaha knew they had to shatter the weight thing once and for all, so where the Apex and Vector lines are street-bike based, the Phazer models are dirt-bike based. We’re talking engine heritage and chassis construction. The Phazer models are powered by a new 2-cylinder 500cc 4-stroke that is more or less two of their 250cc dirt bike engines morphed into a single motor with EFI, high compression and a knock sensor. This ain’t no cheap motor, this is first class high end stuff right out of the gate. Five valve heads let the screamer spin up towards 12,000 RPM, with output shaft speeds geared down to sane levels for drive belt transmission performance.
According to Adam Sylvester, Yamaha Snowmobile Product Manager, the first priority in designing this model was to make it as light as possible without sacrificing strength. Second was to give it a level of handling and responsiveness not found on other liquid-cooled mountain sleds. Third was to tweak the throttle response to give mountain riders more squirt when they hit the gas. Fourth was to maintain the sled’s value. The last piece was styling to make it look as sleek and nimble as it is.
Sylvester continues, telling us the Phazer Mountain Lite’s first two design mandates, light weight and nimble handling, are closely related. Their engineering department began with a lightweight 2-cylinder engine and proceeded to build the sled around it – literally. The engine is buried down into the belly of the beast, as low and as centered as possible. The tube-style chassis is strengthened with Yamaha’s exclusive controlled flow die casting technology, providing a very rigid chassis without a lot of weight. That rigidity allowed the suspension engineers develop a very precise handling suspension setup.

Besides the mass-centralized compact chassis, the Phazer Mountain Lite also has Yamaha’s new sport rider-forward ergonomics. The narrow, YZ-style seat and wide bars are tall and forward to put the rider into a sport aggressive posture for instant inputs and feedback from the chassis, which works awesome in wide open powder bowls when you just want to carve and toss the little bitch from side to side.
One objective was to develop trend-setting styling, in the same tradition of the original Phazer. Yamaha stylists went to work cutting all of the empty space out of the sled. If it didn’t serve a purpose, a gap was eliminated and the outer body work moved inward. You can see this in the hood and bellypan, but it is best executed in the front end. Never before has a snowmobile been designed with a naked front suspension. It’s somewhat common in the sport ATV market. The same holds true for the styling cues on the seat and exhaust. Style-wise the Phazer Mountain Lite is a very good blend of ATV, dirtbike and snowmobile.

Riding Impressions
Don’t be so quick to judge this “little” mountain sled until you have the chance to ride one for a day. Right away, riders see the “80 HP” rating and they think they know how it’s going to work. Uh uh uh. Not so.
80 HP is the peak rating, and this is a four-stroke. That means it makes power across a fairly wide range of engine RPMs, so you don’t have to spin it that high to get it going. While the peak power is more like a 500cc 2-stroke, the bandwidth is more like a 600cc 2-stroke. The bottom end pull could even be more like a 700cc 2-stroke, for a while at least. It flattens out on top instead of continuing to peak, but getting there is actually surprising.
Gearing and calibration do wonders for this little scooter as well. It is geared down significantly from their short track cousins, and the amount of lift and acceleration afforded are met with a reduced top speed and a calibration that really is aimed at off-trail operation.
The front end styling gives one the impression that something is missing, but your eyes quickly adapt to the naked front suspension. We’re not so sure about how this will carve through certain types of wet snow, but it does look rather, well, futuristic. Minimalist, as well.
Riding the Phazer Mountain Lite, you have the sensation of the sled being a true _ size of “traditional” snowmobiles. This is a new sensation from a 4-stroke Yamaha. Up to this point, the 4-stroke Yamahas have been stellar groomed trail cruisers, and the Phazer models are on the other end of the spectrum, being so much smaller, lighter, and agile in comparison. You actually could forget it is a 4-stroke, as it shatters the mold of what we have come to expect from 4-stroke sleds up to this point.
Churning though the deep snow, the engine stays smack in its wide powerband, and the EFI system keeps the little 500 twin humming along smoothly and in tune, all the time. The Camoplast Maverick track is a whopping 144” long with 2” lugs, seemingly overkill for an 80 HP mill, but let that tell you something – this little thing will likely surprise you at where it can go and what it can do. Through the trees you will rule the roost, it’s climbing where it’ll lose ground speed, big time.
Built on a 14” tunnel, ala Firecat logic, the Phazer is narrower and agile, a real boondocker’s delight. There will be a great number of riders who just like playing in powder, not needing to climb to great heights to get their fix, and they will be attracted to the Mtn. Lite in droves. It is about as close as one can get to the flickability of an M-Series Arctic Cat in another brand. There is however, a sway bar up front, which provides stability going down a forest road or trail, but out in the deep it is not really all that noticeable. The balance afforded is well distributed.
Of all the new Phazer models for 2007, our staff agreed that the Mountain Lite was the most impressive of them all. The narrow nature and agility were best suited for the playful riding in deeper snow, and the throttle response gave us impressive capability to flick it around in and out of spots that would usually require greater effort. The sled made you feel like a better rider, a true sign of excellence. Yamaha built this sled to let people go out and ride for not a lot of money and just have a good time.
The 2007 Phazer Mountain Lite is available in one color package – White and Sliver – and retails for only $7,199.

 

2007 Ski-Doo Freestyle – The Freestyle Explosion

Last year Ski-Doo introduced their simpler, lighter, smaller and less expensive Freestyle. Powered by a single-cylinder 300cc, it demonstrated the basic elements of a less complex snowmobile that could be loads of fun without such a high price. Attracting younger riders was the main idea. It was perfectly suited for “tweener” riders – between the pint-sized Mini Z and full-sized fan-cooled sled. Strong sales (many areas were sold out early in the season) confirmed that the market for a lightweight, easy-to ride, radical-looking sled is strong.
While the concept was valid, the narrow ski stance and small engine narrowed the appeal of the machine greatly. Now for 2007 witness the Freestyle explosion. Ski-Doo has broadened its appeal with a more powerful engine and two new packages for more
experienced riders. Once there was one, now there are four. All of the three additional models are powered by a revised version of the twin-cylinder Rotax 550cc fan-cooled two-stroke.
The Rotax 550 fan has been in production for a number of years, and gets revised port timing for the Freestyle models to give it even more bottom end and midrange, a re-shape of the powerband (if you will) to best match the application.
The narrow stance 300 is now called the “Freestyle Session 300F”. Also offered is the Freestyle Session 550F, the Freestyle Back Country 550F, and the rad-looking bad-boy Freestyle Park 550F. Where the original Freestyle was intended and equipped mainly for play in meadows and approved areas, with light trail riding, the Park targets more experienced riders who want top performance. The Back Country will especially appeal to riders wanting to head into deeper snow for freeriding, or snowboarding.
All of the Freestyle models remain true to the vision; smaller, simpler less complex sleds that are less expensive and within the reach of more buyers, especially younger ones.

Freestyle Park
Here is the extreme Freestyle sled, ready to take on trails and stunt parks. The orange and black Freestyle Park is a tricked-out model with upgraded shocks, more powerful engine and race-style handlebars. Eating up bumps – in the trail or snow park – are standard HPG shocks in the front and rear, as well as the snocross-proven SC-4 rear suspension. For stable cornering, the ski stance is widened to 39” and a sway bar is added. A 121” x 15” x 1.25” lug track boosts traction.
With the added power of a standard 550cc fan-cooled engine combined with the ultra lightweight and nimble RF platform, trail riding and playing in snow is really fun. The official dry weight spec is 410 pounds! Trail ride it, play with it, it’s all good. For ultimate maneuverability, Rotax Electronic Reverse is standard.
Of course, Ski-Doo designers had to match these upgrades in substance with upgrades in style, too. The Freestyle Park looks trick with an extra-low windshield, riser block, J-hooks and Acerbis handguards. The body reflects a radical attitude with new grey body panels with spicy orange hood and graffiti-style graphics.
The 2007 Ski-Doo Freestyle Park sells for $5,849.
Freestyle Back Country
The new long-track Back Country package improves your capability for heading into deep snow and freeriding. The more powerful 550 Fan engine does a surprising job at spinning the 136” x 16” x 1.25” PowderMax track, and with an official dry weight spec of 415 pounds (four hundred fifteen – no, that was not a typo) the Back County floats where others sink. Pulling this one out of the rhubarb is equally as fun; it’s really much less of an issue.
You can bang on this one as well, as it too is fitted with the capable SC-136 rear suspension and HPG shocks, front and rear. The wider 39-inch ski stance and sway bar makes it very trail capable as well, giving the Back Country a wide swath of conditions that it works well in. A speedometer, cargo rack and center grab strap are all standard issue as well.
The 2007 Ski-Doo Freestyle Back Country sells for $5,849.

Freestyle Session
For 2007, Ski-Doo is expanding the base Freestyle’s capability on trails, with the added power of the Rotax® 550F engine and a 39-inch ski stance standard. Now riders won’t have to pedal as hard when trail riding, trying to keep up with the rest of the pack. A 300cc/32-inch ski-stance configuration is also still available with the Session package. 550 models also come with a speedometer, standard.
Keeping the Freestyle accessible to its young target, it still starts at an aggressive price point. The 2007 Ski-Doo Freestyle Session 550F retails for $5,399 and the 300F a mere $4,099!

Ride Impressions
Last year we liked the idea of smaller, lighter and less expensive, but felt the single-popper 300 was just not enough. Even for a novice, but maybe a youngster. Getting three new models with a 550 fan is just what the dealers and consumers wanted, and the results are a bullseye. The added torque of the 550 makes for fun ski popping and brisk acceleration, fun but not obnoxious. They remain more of a play sled than an MX Z, but open up the realm of possibilities for younger riders and how they want to use their equipment. Image is everything to them, and these sleds are cool, especially the Park.


We were able to trail ride them extensively, where they performed with ease. The Park was more agile through the trees where the Back Country floated better. Their super light weight makes them a joy to do tricks with where other sleds would land with a “thud”. That’s the idea. Not everyone needs to go at warp 9 to have fun. A new age sled for new age riders.

 

AF-1 Anti-Fog Helmet from Polaris

Polaris has combined development work done in the Polaris engineering center with extensive real-world, on-snow testing to produce the new Polaris AF-1 Helmet, which provides riders with outstanding anti-fog performance.
“We simply cannot get this thing to fog,“ said Pure Polaris Helmet Developer Michael Alessi. “This helmet redefines the term ‘anti-fog’ and we’re excited to provide our customers with a helmet that will make their ride safer and even more enjoyable.”
Polaris engineers worked on the AF-1 in company engineering facilities to determine the best combination of designs, materials and shield coatings for this helmet. Their in-house development work was complemented by rigorous testing on the trails.
To create this helmet of the future, Polaris development specialists studied helmets currently regarded as state of the art. The team identified performance flaws and developed materials and designs to successfully prevent fogging. The result is the technologically advanced AF-1 – the future of anti-fog helmets.
Hard-riding Polaris engineers who log thousands of miles on their personal sleds in their free time became deeply involved in the AF-1 project. These riders cannot afford to have their shields fog up when they’re hundreds of miles from home, so they added their expertise to make the new AF-1 a helmet riders can trust to keep vision clear on every ride.
The AF-1′s PureSeal™ technology is incredibly effective at deflecting exhaled breath so it doesn’t reach the inside of the shield, which is a primary cause of fogging. The newly designed breath deflector has dual venturi exhaust vents to remove exhaled breath. The deflector adjusts to the rider’s face for a customized fit and delivers consistently reliable performance even during aggressive riding.
The shield of the AF-1 features an improved anti-fogging coating that resists fogging from any breath that might escape the deflector and also features anti-scratch properties to keep the shield clear.
The AF-1 has a tough, protective alloy polycarbonate shell and a multi-layer EPS lining for impact protection. Its Nylex liner is removable and washable, the “Quiet Ride” interior enhances a rider’s experience, and there are adjustable crown (top of helmet) and chin vents.
The AF-1 has earned Snell M2005 certification and is DOT-approved.
It is available in Red, Blue, or Silver, each with exciting graphics, for an MSRP of $159.99 US/$204.99 CAN. It also comes in all-black at an MSRP of $154.99 U.S./$199.99 CAN. It is available in sizes S-3XL from Polaris snowmobile dealers or at www.purepolaris.com.

 

X2 Triple Threat Skis from USI

The new X2 Triple Threat Skis from USI are the industry’s first truly “tunable” skis, allowing their handing characteristics to be adjusted based on the needs and wants of the rider as well as snow and riding conditions; from “Mild to Wild” in a matter of minutes!
Ultimate Sports Incorporated (USI) introduced the first composite (plastic) skis to the snowmobile industry almost 20 years ago. UHMWPE (Ultra High Molecular Weight Polyethylene) was the godsend plastic – without it, we would all still be on metal skis. This material has since revolutionized the snowmobile ski is industry. Today’s plastic snowmobile skis are all made of the same UHMWPE and there are a myriad of different design ideas in single, double and triple keel designs using equal numbers of wear bars in most cases. There are some really great ski designs and there are some equally poor ones too. It is up to the consumer to be aware and well educated about matching specific ski designs to their specific application.
USI has long sought the “Holy Grail” of snowmobile skis and the all new X2 Triple Threat Skis are very close. That is a very bold statement, but one that can be backed up by years of testing by USI as the X2 Triple Threat Skis have been in the design and test phase for almost five years.
About the only adjustability most skis provide is to use carbide runners of varying length and diameter. The X2 Triple Threat Skis can do all of this, yet so much more, making them the most adjustable and tunable skis on the market. The reason they are called “triple threat skis” is because they are fully adaptable to groomed trail, mountain powder and all out racing conditions with the selection of three different styles of “Shark Fin” keel plates. USI calls it Shark Fin Technology. In addition to the Shark Fins, they can be changed even further with USI Power Steering Plates that (simply) create a rocker profile, or add curvature, to the ski bottom for lighter steering characteristics. Additionally, “Shaper Keel Plates” can also be added to the bottom of the keel between the wear bar and the keel to create more bite in loose or powder snow conditions. So, with one set of X2 Triple Threat Skis you can go from mild to wild in matter of minutes, tuning your X2 skis for the way you ride where you ride, eliminating the need for different skis for different conditions.
When USI started the X2 Triple Threat Ski design process in 2000 the goal was to create a ski design that really could “do it all”. They took a close look at their own line of snowmobile skis (PX-301, VX-301, SPX-301 and SS Railer) and asked themselves, “How do we combine these attributes and more into one single ski design?”
During design and testing at USI, they had always modified the prototype skis by cutting and shaping and adding or removing pieces in different locations to gain the characteristics they were looking for. This all had to be done in the least amount of time, and on many different makes and models of snowmobiles, which are all different. Some snowmobiles are light in weight and others are heavy. Some have long tracks and others do not. Changes in overall power, suspension design, rider position, weight distribution, caster, camber, keel height, ski width and ski position on the spindle front to back will make one sled handle completely different from another. USI quickly learned they could make one rider extremely happy, yet another was seemingly never be satisfied. Design elements that worked for one application needed to be changed for another.

Shark Fin Technology
The X2 has what no other ski has: interchangeable keel fins, front and rear – “Shark Fin Technology.” These interchangeable Shark Fins allow the rider to change the handling characteristics of their sled in minutes. The balance of weight (front to rear) between one snowmobile and another can be quite different. Because of overall snowmobile drive train and chassis design differences one snowmobile may be a lot heavier in the front than the next. The X2 in its basic form was designed around the heaviest of these snowmobiles with notorious aggressive steering characteristics on hard pack and wet snow.  Some snowmobiles are just so heavy that to turn them with a more aggressive keel design requires too much effort by the rider. If you’re Jack the Bear that is ok, but for most of us on a days ride we want the easiest steering possible: but with the best in corner control. The USI X2 Shark Fins give you this tuning capability.
The rider can also mix and match the Shark Fins of all three stages to suite themselves, all stages are interchangeable. Put the Stage 3 front fin with a Stage 2 rear fin or vise versa as an example. It is totally up to the rider and what kind of control he or she wants.
Power Steering Plates” were introduced by USI last year and were a great success. USI SPX, PX and VX-301 skis are long skis (at 42 inches) and fairly flat running to gain bite in the corners. With some heavy nosed snowmobiles this was a problem in wet heavy or compacted hard snow. To combat this problem USI developed a very simple flat plate called a Power Steering Plate that goes between the mount shoe and the bottom of the ski. With the Power Steering Plate in position, all you have to do is tighten up the wear bar bolts and instantly your USI ski gained a rocker shape.
For those who don’t know, putting a bow or rocker shape in a ski has long been a racers trick since the 1960s to gain lighter steering and faster maneuverability on their snowmobile without sacrificing a lot of grip in the corners. The beauty of a flexible plastic ski like the USI skis along with the aluminum mount systems is that you can easily change the rocker of the ski at will just by adding or removing the Power Steering Plates. No other skis on the market that can do this! The X2 Triple Threat Ski can use these plates as well.

Shaper Plates
Most of us know that riding in powder snow can be a pain if you don’t have enough grip in the turns. Shaper Plates have helped cure this problem on USI skis. Shaper Plates have been around for about 6 years now and they add 1/4 of an inch of depth to any of our USI skis. Plus, they extend laterally on both sides of the keel about 3/8 of an inch with a beveled edge. Bolting these on between the bottom of the USI ski keel and the wear bar using the wear bar studs secures the plate and creates a shape much similar to the Shaper Wear Bars manufactured and distributed exclusively by Stud Boy. Everyone is starting to realize that Shaper Wear Bars are the way to go for the best grip possible in the corners. This hour glass shape is perfect for catching and compacting snow against the keel in loose or powder snow conditions. The result is great cornering in the loose stuff. Imagine being able to add these to your X2 skis with the Stage 3 Shark Fins!

A Complete Ski System
The reason USI calls the X2 Triple Threat Ski a “Complete Ski System” is because of  all the adjustments that can be made to them. This makes the all new X2 Triple Threat Ski system the only truly tunable ski on the market today. Mix and match 3 Stages of Shark Fins, add Power Steering Plates and/or Shaper Plates and you have the widest range of adjustability offered. USI won’t go as far as to say it’s perfect yet, but they believe they are real close.
In the coming years you will see variations in Shark Fin Technology encompassing single, double and possibly triple whale tales or spoilers similar to what cars use. Imagine creating down force or even lift on a ski! USI is doing it and is in the process of patenting many different attachments for this ski as well as some new ski systems already in testing. If you want to get in on one of the newest and most exciting trends in skis to come along since USI invented the plastic ski in 1988, now is the time.
If you want the best in tunable performance products you have to pay a little extra. USI and their dealers sell X2 Triple Threat Skis for $448 U.S., but watch for introductory offers through November and at all the snow shows.

Klim Adrenaline Gore-Tex Boot

The industry’s first GORE-TEX riding boot is “Guaranteed to Keep You Dry®”!
Whether you live to carve through fresh powder all day long, pound out a 200-300 mile day or just ride casually through winter’s beauty, you’ll do it with warm and dry feet in Klim’s new Adrenaline Boot. The Adrenaline Boot is the only snowmobile boot on the market with a GORE-TEX membrane and W.L. Gore and Associates’ famous “Guaranteed to Keep You Dry” promise.
“Our research shows that about 90 percent of competitive boots are neither waterproof nor breathable,” explained Klim President Justin Summers. “But the real soaker for snowmobilers is perspiration, and even those boots that are waterproof won’t let that escape.” The Adrenaline Boot’s GORE-TEX membrane and multi-layer perforated construction meets Gore’s stringent standards for breathability. That means when sledders get moving and their feet start to sweat (more than a pint of sweat a day) the Adrenaline Boot will draw that moisture out to the world, keeping socks as warm and dry as when the ride started!
“We built the Adrenaline Boot for serious snowmobilers because we designed them for ourselves,” said Summers. Consumers will find a tough, abrasion-resistant composite outsole with a Kicker Toe to protect the boots from wear caused by traction strips and tunnel bolts. “Our new polyurethane midsole resists packing out better than competitive EVA midsoles,” he added. “We put our Adrenaline Boots on some of the most aggressive, gear-abusing riders we know for thousands of miles to prove out their durability. These boots are made to thrive in the harsh usage serious snowmobilers put their gear through.”
The new Adrenaline Boot features 600 grams of 3M Thinsulate™ insulation. This offers excellent warmth protection without adding bulk. “The Thinsulate material we use in the Adrenaline Boot is one of the thinnest and toughest insulations on the market. It takes a beating and retains its loft without retaining moisture,” said Summers.
Riders will appreciate Klim’s attention to ankle support and flexibility. The Adrenaline boot is not as stiff as many of the “snowcross” or “snowboard” boots currently on the market. “One of our goals for the Adrenaline Boot was to design it so that people can actually walk in them,” said Summers. “We started with a molded composite skeleton for lateral stability and then worked on the right cutout shape to allow good forward flexibility at the ankle. Owners will be very happy with the walkability of the Adrenaline Boot.”
Klim brought some of the first snowmobile-specific GORE-TEX jackets and pants to the market, and now offers the first Gore-Tex boot to snowmobiling. “We have a very strong working partnership with the team at Gore,” noted Summers. “That relationship has allowed us to offer snowmobilers the best, most technically advanced riding garments in the world.”
The Adrenaline Boot will be available as Klim Dealerships in the Fall of 2006. Offered in sizes ranging from men’s 7-14 with a retail Price of only $159.99. Visit www.klimusa.com to find the nearest dealer.

 

1972 Brut LC44

Brutanza Engineering Inc. was formed in 1971 by former Polaris personnel that had worked in Research and Development and raced out of the factory race trailer.
Jerry Reese, Marley Duclo and Mike Baker had been responsible for numerous race victories and design innovations. An opportunity by a group of investors in Brooten, Minnesota was presented to Jerry Reese, with the goal of building a high performance snowmobile.  In just 11 months, these individuals put together a team that would design, source an engine supplier, set up a manufacturing facility and begin building snowmobiles. That year a total of 1500 Brut LC44 snowmobiles were built – an amazing feat when you look at the time it took FAST to bring their Blade to market.
In the early 70′s, “High Performance” still meant being the first across the lake, but the consumer also demanded a machine that could run hard in ditches. Remember, snowmobile trails for the most part in the early 70′s were scarce, and in many areas simply did not yet exist.


The 1972 Brut LC 44 would bring a number of “firsts” to the snowmobile industry. Brutanza Engineering marketed the Brut as the “Third Generation Snowmobile”.
The management group at Brutanza Engineering set out with specific goals to address reliability and performance issues of current snowmobile designs. The objectives were:

-    Design and build a Liquid Cooled (3         cylinder) engine.
-    Reduce belt breakage
-    Lower the center of gravity
-    Maximize performance without com        promising reliability.

Jerry Reese had experience with liquid cooled two stroke motors during his days with Polaris. Polaris had been testing liquid cooled (LC) engines in the late 60′s and early 70′s. He knew that liquid cooling would provide consistent engine temperature and eliminate the problems associated with free air engines such as fouled spark plugs, excessive noise, vapor lock and poor performance when air temperatures increased. As a side note, Polaris would not race an LC motor until the ’76 season, and the first production LC model would be sold in ’77.
The motor designed by Jerry Reese was manufactured by Fuji Light Industries of Japan, who was also building engines for Chaparral at the time. Everything except the crankcase was shipped to the Brut factory where the motor was assembled. The crankcase was built in the USA with tooling that allowed a triple and, in ’73, a twin (294 cc) to be built.
The Brooten engine was a 439 cc triple with a three into one exhaust. Why a triple 440 you ask?  Lighter power spikes and better internal balance, which translates into fewer clutch problems. Or so was thought – more on that later. The port timing was conservative on this engine, which produced 50 hp @ 7200 rpm in its first year of production.
An innovative feature that was used to maintain consistent cylinder temperatures and reduce plug fouling was to restrict water flow to the PTO cylinder, which was found to run the coldest because of higher water flow. The orifice size on the inlet manifold was machined to provide balanced water flow to the cylinder head.
The motor also featured CD ignition which in 1972 was only found on factory race specials and select special build stock race sleds. It was another innovative feature that improved engine reliability.
Drive belt failure (blowing a belt) was commonplace on snowmobiles of the era. Anyone who snowmobiled in the early 70′s likely remembers having to carry a couple of belts on their person. Belts draped across your shoulders were so common, you were never finished dressing until you had a belt slung around your shoulders.
Marley Duclo and Mike Baker set out to solve one of the main contributors to drive belt failure: “clutch mis-alignment” between the primary and secondary. The “Power-Pac” drive train was a patented design whereby the engine and jack shaft were connected.


The industry standard at that time was to use a motor mount plate fastened directly to the crankcase with rubber bushings sandwiched between the mounting plate and chassis. The softer the bushings, the less transmitted vibration to the chassis, but the greater the degree of clutch mis-alignment under load. As HP increased, the motor mounts became more complicated which resulted in more weight and complexity. High durometer bushings were used, but they transmitted engine vibration to the chassis.


The “Power-Pac” design did not require a motor mount plate. The crankcase was supported using mounting lugs attached directly to the frame. A third mount is attached directly to the PTO cylinder head and the tunnel. The mount incorporated a bearing which supported the jackshaft and secondary clutch. The opposite end of the jackshaft was supported by the tunnel mounted chaincase.
This arrangement prevented misalignment between the primary and secondary clutch, as the engine acted as a rigid connection between the two. The design also did away with high durometer rubber bushings which minimized engine vibration transferred to the chassis.
The “Power-Pac” drive train required the engine to be laid down with the triple carbs pointed straight up to receive cool fresh air. Cool, dense air translates into more HP.  The major draw back for this engine arrangement was the limited space for the exhaust. Marley Duclo would design triple pipes for a (100) limited build sleeved down 439cc to a 398 cc  X-Country sleds for the  1972  I-500 Winnipeg to St. Paul race. The engine layout also lowered the center of gravity of the sled, to improve handling. Curiously, the Arctic Cat Firecat has taken this original Brut design element further by tipping the engine back and casting cylinders with the intake and exhaust ports on the same side. This provides all the benefits of the Brut with more room for a properly designed exhaust system.
In retrospect, the engineering that went into minimizing engine vibration transferred through the drive train and going with a three cylinder engine went up in pieces (literally) that first year. The Salsbury primary clutches used on the ’72 models were prone to failing. The problem was traced to a flaw in the casting.
Forced to come up with a primary clutch, Jerry Reese would design a primary clutch that used a cam (similar to a helix) which made the clutch not only rpm sensitive but also torque sensitive. A similar version is still available as an after market clutch.
The final major design feature, patented by Brut, was the design and application of tunnel mounted cooling extrusions. The original ’72 Brut used a radiator mounted in front of the driver under the hood. The sleds were prone to over-heating when idling at the start line for many cross country races. Midway through the ’72 race season, the factory team appeared with finned copper tubes running along the inside of the tunnel side walls. This design would evolve into an finned cooling extrusion mounted with the fins facing upwards. This allowed snow to build up in the cavities, which would maximize cooling efficiency. To circumvent the Brut patent, other sled manufactures would mount the heat exchangers above the track, under the running boards or in the front bulkhead.
Brutanza Engineering would build snowmobiles as an independent company for three years. The costs associated with upgrading the ’72 production with new clutches and the oil crisis hurt the company financially. In 1975 Brutanza Engineering was sold to Scorpion. The snowmobile was sold as the Scorpion Brut and offered in a 340 cc twin and 439 cc triple.
Scorpion built the sled for one more year in 1976, under the Massy-Ferguson brand name as the Cyclone. The major design upgrade was the addition of Mikuni VM-34 carbs .
Many of the design innovations brought to the consumer in the ’72 model year truly demonstrated “Out of the Box” thinking.  A snowmobile with unconventional design offerings is not for everyone, however, the  innovations found on the Brut and other independent designed sleds have brought major design breakthroughs to this sport to build  the “Next Generation Snowmobile”.

 

Damaged RX-1 Spark Plugs

Owners of 2003 Yamaha RX-1s may experience poor performance or ignition misfiring caused by a poor connection between the coil caps and spark plug terminals. The original spring clips used inside the plug caps could cause the coils to not be held securely on the spark plug. This can cause the coil to “notch” the threaded end of the spark plugs, leading to a poor connection and resulting in misfiring.
If you witness deformation of the spark plug ends, or find the coils to be loose fitting on the spark plugs, you can upgrade to the newer style updated ignition coil caps that have a revised style spring clip. Order Yamaha part #8FA-82310-01-00.
