Features
|
Instantaneous Lift
The combination of the raised and lightweight AXYS® chassis, a powerful Polaris® engine, and the Polaris-exclusive track designs pop the RMK® on top of the snow.
|
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.
|
Multiple Track Options
RMK® Assault® riders have a choice between the Peak 2.25" track and the Series 6 2.6" track. The Polaris®-exclusive Peak 2.25" track is ideal for mixed hard pack and deep snow conditions providing impressive traction and control. The single-ply design features a stiffer lug base with flexible tips to provide a hybrid of speed and flotation. The Polaris®-exclusive Series 6 2.6" track provides the ultimate mountain performance, and the lightweight track is designed for improved snow and hard pack traction and better lift.

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.

Walker Evans® Shocks
Walker Evans® Needle Shocks with compression adjusters and remote reservoirs offer the best in tunability and fade-proof performance. Unique needle design uses hydraulic force at the end of the stroke to eliminate harsh bottoming. |
Chaincase Drive System
The RMK® Assault® uses the tried and true Polaris® chaincase drive system to deliver the perfect combination of strength and performance for cornice drops, jumps, and attacking the terrain.
