2025 Polaris PATRIOT BOOST PRO RMK 155

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.

Features may include:

• 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.
