Features

The Best Mountain Sled Just Got Better - and Even Lighter

  • 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 seat design and running boards further improves rider mobility on the sled while the 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.
  • 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.

Ultimate Control

  • LIGHTNING-FAST RESPONSE. PUTS THE POWER DOWN.: QuickDrive is the lightest drive system in the industry and produces the lowest inertia for optimum response. Choose between the 325 Series 9 Track for instant traction and forward drive in deep snow or the 275 Series 8 track for versatility and traction in varying snow conditions.
  • PRECISE STEERING. CONFIDENCE INSPIRING.: The RMK React Suspension lets riders effortlessly initiate sidehills and experience less fatigue with the most predictable ride. It includes a 36"-38" stance, a sway bar designed for predictable handling, and forged a-arms and spindles optimized for strength and durability.
  • LIGHTWEIGHT AND PRECISE.: Choose from two shock options. Ultra-premium Walker Evans Velocity Shocks are the best of the best in various mountain conditions. They feature remote reservoirs for increased oil capacity to ensure all-day performance and durability, along with compression adjusters to dial in the ride. The Walker Evans Lightweight Monotube Shocks are standard and feature a simple and durable one-piece design.
  • The RMK Matryx Slash platform features a next-level rider interface and slashed, tapered tunnel. Combined they deliver minimized drag and maximum control.

Ultimate Control in the Steep & Deep

  • 1" LOWER SEAT DESIGN: Easier Maneuverability in Deep Snow.
  • THROTTLE SYSTEM: All-day control.
  • REDESIGNED RUNNING BOARDS: Better Clean-Out for Improving Riding Experience.
  • REDESIGNED HEADLIGHTS: Redesigned to be Lighter-Weight, Yet Durable.
  • When we build a sled, we build it to be the best sled for each unique riding style, not simply a different sticker or name. Every part is scrutinized to deliver what you need as a rider. For 2025, we've made refinements to deliver an even better riding experience in the backcountry.
