2014 Polaris® 800 PRO-RMK® 163 Lightest. Strongest. Most Flickable. These are deep snow machines that were developed by mountain riders for mountain riders. These RMK® models are lightweight, powerful, and have extraordinary handling in all types of snow and terrain. They’re the lightest, strongest and most flickable sleds on the slopes. Standard Features May Include: Lightest 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. The Polaris® PRO-RMK® 155 weights in at 417 lbs. That is 42 lbs lighter than the Ski-Doo® Summit X. 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. Power and Strength to Dominate The Polaris RMK Chassis is used by Polaris Hillclimb Racers and has been race-proven to have the Power and Strength to Dominate. In the 2012-13 race season, Polaris racers in the RMSHA circuit won 10 RMSHA PRO class points titles and went 23 for 24 in Stock class victories. QuickDrive™ - Low Inertia 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. 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" 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. 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.
