Standard Features

PowderTrac™ - Running Boards
 The PowderTrac™ running boards have been developed for maximum snow clean out and maximum strength. Built from extruded aluminum with bonded cast lugs, they boast an open area of 50% and integrated traction that is machined in for sure footed performance.  
Pro-Lite Seat
 Mountain snowmobiling has changed and so has its seat. Shorter by 5.5 in. allowing you to easily swing a leg from one side to the other —along with a 3.75 in. wider, flatter area for more comfortable seated riding.  
PRO-RIDE™ Chassis with Carbon Fiber Overstructure
 Confidence comes standard. When you have a sled that responds to your every input, you’ve got a sled that you can trust. From technical tree riding to a demanding sidehill and turn out, the PRO-RIDE™ chassis helps make you a better rider. Better weight transfer for Rider Active Control, and 300% more rigid chassis for more precise handling. Now with carbon fiber overstructure for reduced weight without compromising strength.  
Raw Refined
 The low-profile LED tailight, lightweight punched snow flap with hand access and carbon fiber bumper with extruded billet mounts add style and function. The narrower tunnel cooling extrusions save weight.  
 ProTaper® Bars  
 High-rise aluminum design and adjustable bar clamp creates an optimum riding position that can be tailored to your riding style. Bar hooks and race-style master cylinder round out the purpose-built controls.  
Competition-Spec Front End
 Wide and adjustable, this RMK® can be dialed for your exact needs. Stiffer sprung and valved, compression adjustable Walker Evans® Piggyback shocks are matched to a swaybar-less design.  
Race-Proven Suspension
 Walker Evans® 16-position compression adjustable needle shocks and heavy-duty springs are ideally suited for tearing up Jackson Hole moguls or dropping cliffs.  
Lightweight Silencer
 The silencer has been designed to keep noise levels and overall weight in check.  
Lightweight Rotor & Jackshaft
 Reducing rotating mass allows for a sled with quicker response. Lightweight, purpose-built RMK® brake system. Featuring the proven Cyclone master cylinder mated to a lightweight, single-piston caliper.  
Multi-Function Gauge
 Versatile design allows you to swap tach & speedo positions, monitor hours, temperature, trip odometers and overall distance. Features a built-in recorder which logs up to 3 minutes of run time, which can be played back. Riders are able to choose fuel type through the multi-function gauge — an ethanol jumper plug is no longer required.  
Coil-Over Rear Suspension
 The heart of any mountain sled is the rear suspension. The RMK® Coil-Over Rear Suspension is designed for better flotation and deep snow performance with improved on-trail ride. By eliminating the torsion springs and redesigning the torque arms, this skid weighs substantially less. In addition, it is tunable to the snow conditions. A simple turn of the spring preload adjustment allows you change your set-up from deep powder to crusted snow.  
2.125 in. Competition Track
 Stiff durometer construction is ideally suited for hillclimb and backcountry use. Pre-punched for quick snow cleanout.  
Key Benefits
 Deep snow capability  
 Durable & dependable  
 Race proven
