Features

Features

  • ROTAX 850 E-TEC ENGINE - MORE POWER YOU CAN FEE: 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 acceleration you demand.*Observed HP measured on internal dyno test in optimal conditions for 2-stroke engines.
  • SHORT TUNNEL - DROP THE DRAG: Go more places with a shorter tunnel length allowing optimal maneuverability in deep snow thanks to exceptional snow evacuation. Standard rear lightweight snowflap with LinQ-ready attachment points to attach optional removeable long snowflap.
  • DYNAMIC HANDLING - A MORE CONFIDENT RIDE: Revised ski spindle and ski stopper for more predictable handling and a confidence-inspiring ride on steep sidehills and rough terrain.
  • ONE-PIECE LIGHTWEIGHT HOOD - LIGHT AND AIRY: One-piece Polypropylene construction instantly drops 6.2 lbs. of weight. Optimized ventilation for heat dispesion and noise reduction.
  • TMOTION REAR SUSPENSION - CARVES WITH YOU: The tMotion flexes laterally, reducing the effort to initiate a roll, due to a ball joint at the center hinge between the rear arm and drop link and split flat-tube front arms. Very progressive motion ratio makes the ride on trails even more comfortable.
  • E-TEC SHOT STARTER - EASIEST STARTING: 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.
  • 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.
  • ERGONOMIC - DEEP-SNOW DESIGN: Purpose-built for a better deep-snow experience with lower seat height, smaller diameter handlebars and low handlebar strap for the ultimate advantage in deep snow.
  • FULL-LENGTH PROFILE RUNNING BOARDS - SURE FOOTING: Rigid full-length extruded aluminum grid-style design with wide openings for exceptional snow evacuation and superior grip. Flat foot positioning for comfort and control, plus a 1 lb. weight reduction. (X packages only)
