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. Carbon fiber overstructure for reduced weight without compromising strength.
PRO-LITE Seat: Mountain snowmobiling has changed and so has it's seat. Shorter by 5.5" allowing you to easily swing a leg from one side to the other —along with a 3.75" wider, flatter area for more comfortable seated riding.
Reduced Weight: In 2011, we introduced a 431. lb. PRO-RMK® 155. Now, when most sleds have gained weight, we continue to build ‘em lighter and stronger. Our PRO-RMK® 155 weighs in at 417 lbs. A weight normally reserved for high-dollar, custom-built mod sleds.
Lightweight Silencer: The silencer has been designed to keep noise levels and overall weight in check.
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.
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.
Structural Adhesive Bonded Components: By using technology to improve our manufacturing, we continue to build lighter stronger sleds. Bonded lower control arms featuring forged aluminum ends and steel tubing. This process makes for a set of control arms that are 2 lbs. lighter.
QuickDrive™ Low Inertia Drive System: The QuickDrive™ Low Inertia System is designed to provide quicker acceleration and increased “flickability” through reduced rotating mass. Not simply a belt-drive, it is a complete lightweight drive system — featuring an extruded drive shaft, lightweight brake, RMK-specific brake caliper and of course the most visible piece of the system — a maintenance-free belt drive that requires no oil or tensioner system. The complete system reduces rotational inertia by 21% which means 5lb. less effort when carving.
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.
800 Cleanfire® Engine: This liquid-cooled Cleanfire® engine with semi-direct injection (SDI) deliver outstanding throttle response and instant acceleration. These powerful, efficient engines produce the impressive power-to-weight ratios that deep snow riders demand. Cleanfire® engines start easily and reliably and they calibrate automatically as the temperature and elevation change. These engines deliver impressive fuel economy in real-world riding situations, which, for Polaris riders, means aggressive, up-tempo riding, not low-rev lab conditions.
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.
Walker Evans® Coil-Over Shocks: PRO-RMK® shocks are a rebuildable, IFP, mono-tube design.
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.
Optional Security System: Prevents unauthorized driveaway of idling sled. Can be installed by dealer on sleds with PRO-RIDE™ gauge.
