Features

Features

  • ROTAX 850 E-TEC TURBO ENGINE - ELEVATION DOESN'T STAND A CHANCE: The first-ever factory-built 2-stroke turbocharged engine in any industry. The Rotax designed and built turbo provides full 165 HP from the industry’s strongest 850 twin up to 8,000 feet of elevation and maintains a 40-HP advantage compared to normally aspirated 850’s. Sophisticated design integrates flawlessly with the REV Gen4 platform for ideal balance at minimal weight. Ultra-impressive power, instant response with no lag, and factory reliability from a turbocharged 2-stroke - only the industry’s leading manufacturer could develop and stand behind it.
  • 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.
  • 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)
