Features ROTAX 850 E-TEC ENGINE: More power you can feel. The most powerful 2-stroke engine in the industry.* It pumps out 10 more horsepower (165 hp) than its predecessor, but its responsiveness is what really shines. With the new pDrive primary clutch, it’s 30% quicker responding than the 800R E-TEC giving you the instant control you demand. *Observed HP measured on internal dyno test in optimal conditions for 2-stroke engines. PDRIVE CLUTCH: Quick, efficient, easy. A major factor in the quickness of REV Gen4 sleds is the new pDrive clutch. Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this 100% new clutch. The oversize rollers with needle bearings, wide flyweights and shaft-on-shaft design emphasize smooth operation and long life. Ultra-responsive shifting, impressive RPM consistency and 2.8 lb. (1.3 kg) lighter than the TRA VII. REV GEN4 PLATFORM: Next generation of a legend. You’ll realize the benefits of our trail and mountain teams’ close cooperation in developing this sled because it has all the right features for both types of riding. It’s incredibly responsive and agile in cornering and boondocking, thanks to its centralized masses and light weight. Not to mention the power and instant response of the 850 E-TEC engine is ideal for hammering out of corners and powering out of a hole. CMOTION REAR SUSPENSION: Crossover control and carving. Crossover-specific suspension uses best principles of the rMotion trail and tMotion mountain skids for confident cornering and agile boondocking – such as rigid front and rear arms with excellent weight transfer. It also features a rising-rate motion ratio, like the latest generation of Ski-Doo rear suspensions, to provide superior control and comfort. Tipped rails enable better cornering, boost top-end speed, fuel efficiency. RAS 3 FRONT SUSPENSION: Crossover precision. Similar geometry and steering to the RAS 3 mountain front end for capability and light steering feel on- and off-trail. Optimized for crossover usage, two ski stance positions dial in handling: 40.1 in. (102 cm) or 38.4 in. (97.5 cm). KYB PRO 36 REAR SHOCK: Race-proven capability. Race-proven aluminum shock with no-tool compression damping adjustment. E-TEC SHOT STARTER: Push-button starting with almost no added weight. After an initial pull-start, the engine charges an ultracapacitor. Pushing the handlebar SHOT button for subsequent starts uses energy stored in the ultracapacitor to turn the magneto into an electric motor that rotates the flywheel, and with E-TEC technology, starts the engine. Eliminates nearly 20 lb. (9 kg) compared to conventional electric start. SHOT starting is only possible with Ski-Doo-exclusive E-TEC technology.
