2015 Polaris® 800 PRO-RMK® 163 Terrain Dominator® Series

2015 Polaris® 800 RMK® Assault® 155

• 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

We know that weight matters. We look at every component and work to make it lighter and stronger. Through our use of industry-leading materials and technology we deliver on it.

• 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.

• 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.

• 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.

• 2.125" Competition Track

Stiff durometer construction is ideally suited for hillclimb and backcountry use. Pre-punched for quick snow cleanout.
