840cc liquid-cooled. 155-inch track. Mountain-built.

The 840cc liquid-cooled twin feeds the RMK React front suspension and standard RMK rear, both tuned for deep powder. Gripper skis and a 155-inch track carve the steep stuff. QuickDrive2 transmission handles variable terrain without lag. IFP shocks across the front and rear keep the sled composed on technical lines. Hand and thumb warmers come standard.
