QUICK, AGILE AND PRECISE

The sled that defines the mountain segment: the PRO RMK. Lightweight, rigid, and perfectly balanced, the Pro always wins when the terrain is deepest and steepest. The 155" track provides a nimble and responsive ride in technical terrain.

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.

Immediate Response

  • POWDERTRAC® XT RUNNING BOARDS - 850 MODELS: The lightweight PowderTrac® XT Running Boards were developed for extreme riders with geometry for improved sidehilling and deep snow capabilities. The improved ergonomics maintain usable space for the rider and traction at the rear of the boards.
  • LIGHTWEIGHT: Polaris snowmobiles are the lightest sleds on the mountain. They have always been light and rigid with added strength and durability while reducing weight on the RMK AXYS platform. Providing riders with instantaneous lift, Polaris sleds help riders get up on top of the snow faster.

Instantaneous Lift

  • 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 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.
  • ENGINE CHOICES FOR EVERY RIDER: Built to integrate seamlessly with the lightweight and agile Polaris chassis, Polaris engines feature class-leading power-to-weight ratios and set a benchmark for ultimate performance with our complete line-up of powerful options.
  • REAR SUSPENSION: The lightweight, rigid rear suspension design features revised geometry to control pitch. This improves weight transfer, delivering better control and a more compliant ride. The rigid suspension delivers power directly to the snow. Off-trail, riders will notice improved weight transfer while maintaining the approach angle. On-trail, riders will notice a more compliant and comfortable ride. The rear suspension features a rail design that helps lift the rear skid while driving it forward.

Rider Balanced Control

  • AXYS BODY PANEL DESIGN: The AXYS PRO RMK features a compact body panel geometry and design that help give the sled the best lean angle in the industry allowing it to hold even the steepest sidehill lines. The PRO RMK does not "panel out" like other sled brands.
  • PRO RMK REACT SUSPENSION: The PRO RMK React Suspension provides riders with the most precise and effortless ride in the deep snow. Effortlessly initiate sidehills and 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.
