Features

Additional Features

  • PRO-LITE SEAT: Mountain snowmobiling requires a different seat design and that is what Polaris delivers. The PRO-Lite seat is shorter to allow you to easily swing a leg over from one side of the snowmobile to the other.
  • MESSAGECENTER GAUGE: Informative and easy to read, this gauge keeps a rider aware of sled operating conditions and provides a wealth of additional data.
  • LED LIGHTS: All models built on the AXYS platform feature standard LED headlights to deliver the industry's best lighting that is 80% brighter than incandescent lighting.
  • MOUNTAIN HOOP: Re-designed in 2016, the mountain hoop is more ergonomic and has been moved down 2.5" to prevent hitting the rider in the chest when in steeper terrain. Now a once-piece, stylized design, the mountain hoop is made of durable polyurethane material.
  • XT HYFAX - 850 MODELS: The profile design has been optimized for lighter weight while maintaining durability.

Immediate Response

  • SNOWCHECK EXCLUSIVE QUICKDRIVE2 (QD2): Introducing the all-new, SnowCheck Exclusive, low-inertia QuickDrive2 (QD2). QuickDrive is the lightest drive system in the industry and produces the lowest inertia for maximum flickability. QD2 boasts a 10% gear reduction for even quicker response and track speed. The system has been optimized for 2.75” track lug heights.
  • SNOWCHECK EXCLUSIVE SERIES 8 TRACK: The all-new, SnowCheck exclusive, lightweight Series 8 track features a 3.5” pitch and optimized 2.75” lug for less mass and reduced inertia resulting in quicker response, instantaneous lift and optimum flotation for the ultimate in all-mountain performance.

Instantaneous Lift

  • PATRIOT ENGINE: Designed for class-leading durability, responsiveness, unrivaled acceleration and industry's best power-to-weight. The most powerful snowmobile engine ever built by Polaris.
  • AXYS CHASSIS: The raised AXYS chassis increase clearance and reduces drag to keep you on top of the snow. It is purpose-built for mountain riding and allows for improved sidehilling, faster and easier climbing, and instantaneous lift allowing the sled to pop onto the snow faster. The aluminum over structure is lightweight and durable for all types of riding. Taller spindles increase clearance to reduce drag.

Rider Balanced Control

  • PRO RMK REACT FRONT SUSPENSION: The PRO RMK React Suspension provides riders with the most effortless ride in the deep snow. Experience less fatigue with the most predictable ride. It includes a 36"-38" stance, a sway bar designed for predictable handling, and forged a-arms and spindles optimized for strength and durability.
