Built for the steep and deep. The PRO RMK delivers unmatched precision, lightweight control, and lift in technical terrain. With rider-first ergonomics, refined power delivery, and track-ready design, this mountain sled leads the charge.
Refined for 2025
Up to 7 lbs. lighter with a new throttle system, 1" lower seat, redesigned running boards, and lightweight headlight—providing even better connection and control.
Rider-First Design
Matryx RMK platform features a narrow tank, console, and seat for better sled control and agility. New design lets you move effortlessly through technical climbs.
Precision Rear Suspension
Optimized rail geometry drives power directly into the snow. Available in 155" and 165" lengths with rigid design for line-holding precision.
Choose Your Power
Three engine options: Patriot 850, Patriot 9R (ultra-responsive), or Patriot Boost (factory turbo). Pick your perfect mountain weapon.
Matryx Slash Platform
Slashed tunnel and advanced rider interface reduce drag and boost control. Designed for maximum backcountry performance.
QuickDrive System
The industry’s lightest drive system. Choose Series 9 Track for deep snow grip or Series 8 for all-around traction.
React Front Suspension
36"-38" adjustable stance with forged a-arms, sway bar, and optimized geometry. Easier sidehills, less fatigue, more control.
Walker Evans Shock Options
Choose Velocity Shocks for premium adjustability and cooling, or Lightweight Monotube for durability and simplicity.
