Lightest. Strongest. Most Flickable.

Polaris® RMK®

Terrain Domination® on a Polaris RMK®, the ROCKY MOUNTAIN KING, is having the ability to go places and see possibilities no one else can. It's about having complete confidence in your sled, knowing that it's ready to react and perform like no other. It’s about elevating your riding ability, whether you’re a seasoned pro or you’re just getting started. It's about being the lightest, strongest and most flickable. In the deep powder, you’ve got to be able to react. To pick your line up the steeps, or sidehill through the trees, you need a light sled with enough power and snap to throw it around. Ride harder and own the mountain like never before.

Looking for a snowmobile that provides a different ride experience such as crossover or trail sleds, head to find a snowmobile.

The 2017 RMK® Lineup





The SKS is the most versatile deep snow crossover sled.



The RMK® Assault® is the backcountry original. Tough-as-nails for extreme conditions.



The RMK® 144 is for 50/50 crossover riders that want deep snow maneuverability with Rider-Balanced™ on-trail confidence.


The AXYS® RMK® features a patented, raised chassis that increases clearance and reduces drag to keep you on top of the snow. This allows for improved sidehilling, faster and easier climbing, and instantaneous lift allowing the sled to pop onto the snow faster. The carbon fiber overstructure offers reduced weight without compromising strength. New, taller spindles increase clearance to reduce drag.


The Polaris® RMK® features industry-first Forged Aluminum A-Arms. The one-piece, forged a-arms are lighter (approximately 1.5 lbs lighter) while providing optimal strength. Forging is widely used and proven through the automotive industry. This design reduces unsprung mass leading to a better ride quality and increased maneuverability.

Optimized Rail Design Reduces Weight While Adding Strength

'The lightweight, rigid rear suspension design is 3 lbs lighter while the new rail is 15% stiffer vertically. It features revised geometry to control pitch which improves weight transfer, delivering better control and a more compliant ride. The rear suspension features a durable, lightweight rail design that helps lift the rear skid while driving it forward. Polaris uses design optimization software to analyze the loads and stress points for various systems and components of the snowmobile. This allows the team to design lightweight yet durable and strong snowmobiles.

Proven 800 Cleanfire® H.O. Engine

'Developed in conjunction with the AXYS platform, the proven 800 Cleanfire® H.O. Engine delivers +10% increase in power-to-weight ratio and quicker throttle response to generate instantaneous lift. The integrated mounting position optimizes the balance of the chassis. Featuring:

  • 3-stage electronically-controlled exhaust valves
  • Electronic oil pump
  • Thermostat with bypass warms up to operating temperature 40% faster and improves durability
  • High-efficiency intake and exhaust
  • VForce Reeds
  • Lightweight crankshaft
  • New throttle body that's lighter and reduces throttle effort
  • Grooved Piston
