Features

Features

  • ROTAX 600 EFI ENGINE - MODERN 2-STROKE EFFICIENCY: 600cc-class fuel injected engine delivering 85 horsepower and outstanding economy at an incredible value. Designed based on the 600R E-TEC with proven reliability and ease of ownership at its core with an outsized fun factor.
  • 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 and fuel efficiency.
  • RAS 3 CROSSOVER 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: 40.2 in. (102 cm) or 38.4 in. (97.5 cm).
  • 4.5" DIGITAL DISPLAY - ADVANCED INFO: All-digital LCD gauge cluster with flatter viewing angle for an easy-to-read info whether standing or sitting.
  • 15 X 146 X 1.6 COBRA - EXCELLENT TRACTION ANYWHERE: This track features combination of flexible cupped lugs for superior off-trail performance and more rigid lugs for added traction on hard-packed snow.
  • PILOT DS 2 SKIS - DEEP SNOW CONTROL: Single-keel with excellent sidehilling bite, thanks to thin outer edges. Narrow and thin, yet stiff. Shorter behind its complementary spindle with flat tail for easier counter-steering and sidehilling.
