Unmatched Precision in the Technical Terrain.

The PRO RMK delivers balanced and precise performance in the steep and deep.

The Best Mountain Sled Just Got Better - and Even Lighter
The PRO RMK delivers instantaneous lift and lightning fast response. 2025 Boost and 9R PRO RMK models are up to 7 lbs. lighter and have a redesigned throttle system, 1" lower seat, improved running board clean-out, and a lightweight headlight for improved connection and control to deliver the best RMK experience yet.
Rider First Design. Effortless Control
The Matryx RMK platform includes a narrow seat, tank and console that provide improved rider connection to the sled while the narrow bodywork enables more agility and less drag in the snow. The new seat design and running boards further improves rider mobility on the sled while the new throttle system helps you feel connected to the sled on every ride.
Maximum Lift. Maximum Precision
The PRO RMK Rear Suspension features a balanced, optimized geometry and rail design to deliver power directly to the snow to pop up and drive forward. Rigid design allows for precision to hold lines in the most technical terrain. Available in 155 and 165 lengths.
Choose Your Power
With three engine choices from the Patriot Family. Choose the legendary durability and relentless acceleration of the Patriot 850, or the Factory Mods… the ultra-responsive Patriot 9R or turbocharged Patriot Boost.
