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.
  • 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.
  • MESSAGECENTER GAUGE: Informative and easy to read, this gauge keeps a rider aware of sled operating conditions and provides a wealth of additional data.
  • 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.

All-Mountain Architecture

  • AXYS CHASSIS: The raised AXYS chassis increases clearance and reduces drag to keep you on top of the snow. It is purpose-built for mountain riding and allows for faster and easier climbing and instantaneous lift to pop onto the snow faster. The aluminum over structure is lightweight and durable for all types of riding.
  • PATRIOT 850 ENGINE: Built to integrate seamlessly with the lightweight and agile Polaris chassis, Liberty engines feature class-leading power-to-weight ratios and set a new benchmark for ultimate performance with our complete line-up of powerful options.

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.
  • WER® VELOCITY HI-LO SHOCKS: The RMK KHAOS 163 comes with premium WER® Velocity Shocks for the best of the best in various mountain conditions. These have been proven in hillclimb dominance.
