Features

Features

  • RAS X FRONT SUSPENSION - TRUE TO THE TRAIL: Flatter cornering and precision handling in all conditions. Developed in tandem with the rMotion X rear suspension to raise the bar in trail snowmobile chassis performance. Wider, adjustable ski stance and +10mm of suspension stroke maximize stability, capability and comfort.
  • RMOTION X REAR SUSPENSION - THE BAR JUST GOT RAISED - AGAIN: The next level of control, comfort and capability on the trail. Built upon the same rising-rate motion ratio principles rMotion suspensions are renowned for, and then some. Completely redesigned with more travel for unmatched big bump absorbing capability and incredible comfort. Longer front arm with exclusive adjustable angle design ideally mates with the RAS X front suspension creating superior cornering and the precise handling Ski-Doo snowmobiles are legendary for.
  • 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 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.
  • LARGE PANORAMIC 7.8 IN. WIDE LCD COLOR DISPLAY - PESONALIZED ADVENTURE: Wide screen full-color display lets riders truly customize their ride from behind the bars. Choose your preferred sled info, and see app integrated information in a split-screen format with GPS, Bluetooth music, helmet-to-helmet communication and more.
  • REV GEN4 PLATFORM - NEXT GENERATION OF A LEGEND: The 4th generation of the REV platform is designed around aggressive trail riders with a narrow, compact package giving the rider more freedom to move and influence the sled. More centralized masses (especially side-to-side), light weight and industry-leading suspensions make the vehicle ultra responsive.
  • PDRIVE CLUTCH - QUICK, EFFICIENT, EASY: A major factor in the quickness of REV sleds is the pDrive clutch. Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this advanced 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.
  • RS RUNNING BOARDS - ROOM TO ROAM: Designed for aggressive stand-up riding, they are flatter for most of their length, wider and strong. Thicker aluminum sheet (3 mm vs. 1.8 mm), plus front and rear reinforcements to withstand tough landings.
  • PILOT X SKIS - TRACTION POSITIVE: Completely redesigned ski to match flawlessly with the most ride-compliant suspensions in the industry. Offering more positive ski traction and reduced darting for confident performance.
