2013 Polaris 800 PRO-RMK® 155 SC Retro

800 Cleanfire® Engine

• This liquid-cooled Cleanfire® engine with semi-direct injection (SDI) delivers 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.

Adhesive Bonded Suspension Components

• By using technology to improve our manufacturing, we continue to build lighter, stronger sleds. For 2013, we've added 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.

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.

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.

PowderTrac™ Running Boards

• The new 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. The RMK features a new seat design. 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

• World’s most advanced snowmobile chassis – light, rigid and perfectly balanced for precise handling even in the nastiest terrain.

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.

QuickDrive™ Low Inertia Drive System

• The QuickDrive™ low inertia drive 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. Reduces rotational inertia by 21% which means 5 lbs. less effort when carving.

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. New, narrower tunnel cooling extrusions save weight.

Reduced Weight

• In 2011, we introduced a 431 lbs. Pro-RMK 155. Now two years later, when most sleds have gained weight, we continue to build ‘em lighter and stronger. For 2013, our Pro-RMK 155 weighs in at 417 lbs. A weight normally reserved for high-dollar, custom-built mod sleds.

Walker Evans® Coil-Over Shocks

• Pro-RMK shocks are a rebuildable, IFP, mono-tube design.
