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.
  • ONE-PIECE LIGHTWEIGHT HOOD LIGHT AND AIRY: One-piece Polypropylene construction instantly drops 6.2 lbs. of weight. Optimized ventilation for heat dispersion and noise reduction.
  • ERGONOMIC DEEP-SNOW DESIGN: Purpose-built for a better deep-snow experience with lower seat height, shorter riser, smaller diameter handlebars and low handlebar strap for the ultimate advantage in deep snow.
  • 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.
  • TMOTION LIMITER STRAP ADJUSTER DIAL YOUR RIDE: Quickly and easily change limiter strap length for desired ski lift without crawling under the sled.
  • 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.
  • KASHIMA COATED SHOCKS SMOOTH RIDE: Kashima coating delivers silky smooth shock piston movement for consistent cushioning through every bump - big and small. Plus, adds durability for worry-free performance on every ride.
  • 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)
