(From the September 2012 issue of SnowTech)
If you own a Ski-Doo Summit you no doubt have heard of the new tMotion rear suspension that is coming on the 2013 Summit models that allows the rear suspension to pivot slightly (left and right) which allows the rider to maneuver the sled through the deep snow like he is an expert rider with minimal effort.
Normally a sled manufacturer makes you buy the all-new sled to get the all-new technology, but this time around Ski-Doo has made available a retro-fit kit that lets you install the split front arm and pivoting rear arm of the tMotion into your pre-2013 Summit XP model. Yep, you can order kit #860 200 763 for $319.99 and get the front and rear arms in a conversion kit for Summit XP models fitted with the SC-5M rear suspension. Getting the sled to do what you want it to just became a whole lot easier, and your riding buddies will think you are the man as you are doing circles around them in the deep.
