FX Chassis
The Phazer models are built on a all-new platform; the FX Chassis. We’re talking a rigid chromoly tube chassis with CF die cast members; super-trick! It is light (seriously) fitted with a link-style sway bar, double wishbone front suspension, a new ProActive rear suspension (torsion spring), 2-into-1 rear exhaust, wide running boards, in-seat storage, the list goes on and on. Past an obvious lack of rider protection, there isn’t much to complain about. A radiator allows a single tunnel heat exchanger to be mounted far forward for mass centralization. Truly the YZF of snowmobiles, in more ways than one.

Sport Rider Forward Ergos
The Phazer rider position is forward; further than an Apex model, but not quite as far forward as a YZ F (or REV, for that matter). A tall, narrow seats is very YZF-like, putting the rider in the best possible location for aggressive or casual riding. The narrowness of the seat enhances the overall lightweight feel and agility on the trail.
CF Die Cast Frame
Under the sweet-looking skin is a solid CF Die Cast Frame member that is lightweight and strong, adding to the chassis strength. On the chaincase side the chaincase itself in part of the frame for reduced weight and added strength.

FX Gauge w/ Push-Button Reverse
The whole front of the Phazer models are so minimal and “naked” looking that the gauge sitting up top of everything, front and center, really stands out. Mount one of these to a dirt bike and it would! This all-new gauge serves many functions; it displays speed (digitally) in either mph or kph. It also has a digital tachometer, tripmeter and odometer function (displayed one at a time). The gauge displays system warning lights such as engine temp, oil level, low fuel and check engine. A set of graduated bars can be toggled between hand and thumb warmers settings.
To top it off (on all but the base Phazer model) there is a push-button for electronically-activated mechanical reverse! Lights just above it indicate whether you’re in forward or reverse; it’s all standard.

1” x 14” x 121” Rip Saw Track
The base Phazer and Phazer FX models use a 14” wide track with 1-inch lugs in the Rip Saw pattern, and the Phazer GT comes with a slightly less aggressive 1” Hack Saw. We asked Yamaha about this several times, and yes, they’re all 1” lug tracks but different patterns. The new tracks are lighter for improved performance, well-matched to the 80 HP output of the Genesis 80 FI engine. Like the Firecats, it allows the tunnel to be narrower to improve the sled’s ergonomics for this segment.

Taller Mountain Bars & Strap
In order to give riders the best leverage and control in the deep snow and picking through trees, the handlebars are now an inch taller on Apex Mountain and RS Vector Mountain models, fitted with bar hooks and a center grab strap that is not quite as tall, now flatter and shorter with the taller bars.

GT Shock Packages
More and more Yamaha models are offered with the “GT” designation, meaning they’re equipped with the GYT-R piggyback front shocks. These trick shocks offer 20 clicks of compression adjustability and 20 clicks of rebound adjustability for maximum tuning capability to better match individual riding styles and/or riding conditions. Their bigger knobs are far easier to turn than are found on some competitive “clicker” shocks. The added oil volume afforded by the remote “piggyback” reservoirs increase resistance to fade in extreme conditions.

Genesis 80 FI
Previous Yamaha 4-stroke engines utilized street bike engine technology. Now Yamaha has tapped into their dirt bike expertise. In effect, they have taken two of their 250cc 4-stroke engines from their mighty YZ 250F dirt bike and combined them into a brand-new, two-cylinder 500cc engine that screams up to 11,250 RPM to produce 80 HP! The bore, stroke and 5-valve head design comes from the YZF, the rest is all-new. Down Draft Intake, combined with EFI and a lightweight crankshaft provide instant throttle response. A high 12.4 compression ratio is made possible with a Knock Control System, always on and adjusting the system to the max. Run 87-octane fuel and lose a few HP, no problem. An auto-decompression camshaft (holds the exhaust valves open) allows easier starting along with being able to use smaller (lighter) battery and starter. Gear reduction system (50:35) keeps clutch RPM under 8,000 RPM. Anyone familiar with a 250 YZF (times two) isn’t laughing. Party time.
