Features

Features

  • REV Gen4 PLATFORM - NEXT GENERATION OF A LEGEND: Lightweight, strong and durable, built to accommodate 20-in. wide tracks to maximize flotation and traction, while providing the precise handling and benefits of the open cockpit design. Maximum capability on- and off-trail.
  • LINQ UTILITY CARGO BOX - STORE MORE: 135 liters of lockable, weather resistant storage capacity. Incorporated hatchet and saw holder, plus attachment points for bungees and two 16-in. LinQ positions on top for expandable accessory use.
  • MULTI-LINQ PLATE - TAKE IT ALL: Capable of adapting to 16- and 20-inch-wide LinQ accessories to maximize accessory options. Multiple configurations allow up to 125 lb (56.7 kg) cargo capacity.
  • SC-5U REAR SUSPENSION - SPORT-UTILITY VERSATILITY: Our sport-utility suspension. Refined ride both on trail and on top of powder. Articulated rail to maximize deep snow traction in reverse or locked out when towing.
  • AIR CONTROL SUSPENSION - RIDING ON AIR: Driver chooses one of five preload settings for the rear air spring – on-the-fly – with just the touch of a handlebar rocker switch. Wide range of adjustment for tailoring the ride for load or trail conditions.
  • 900 ACE - A MORE POWERFUL FIT: When moving to the REV Gen4 platform the 900 ACE adds an additional 5 horsepower* thanks to new packaging and components, including new air intake, exhaust and pDrive clutch. These updates allow for new engine calibrations resulting in added power.*Observed HP metric based on internal dyno test in optimal conditions
  • EASY SHIFT TRANSMISSION - READY TO HAUL: Easy shifting with multiple gear ratios ideal for heavy towing thanks to its high load resistance. Optimal lubrication for extreme reliability and ultra-quiet operation. Rider-friendly H-L-N shift setup with push-button reverse.
