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.
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.
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.
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.
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.
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.
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.
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.
Walker Evans® Coil-Over Shocks: PRO-RMK® shocks are a rebuildable, IFP, mono-tube design.
