Prove Yourself Above the Tree Line

The RMK® Assault® 155 is a backcountry mountain snowmobile built for extreme conditions. The tough-as-nails sled, featuring Walker Evans® shocks, is perfect for dominating cliffs and jumps. 

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. 

Rider Balanced® Control

The AXYS® RMK® features Rider Balanced® positioning that delivers ultimate control for the rider for precise, effortless sidehilling. 

Immediate Response

The world's best mountain sled is built to be the lightest and most rigid, making it incredibly responsive to rider inputs. This allows you to change direction and maneuver confidently in all conditions.
