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. Ride harder and own the mountain like never before.
The RMK® Lineup

RMK®Technology

RMK®

NEW Patented Raised AXYS® RMK® Chassis

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 for 2016 increases clearance to reduce drag.

FORGED ALUMINUM A-ARMS

Polaris continuously pursues new innovations and technology, and for 2016 the Polaris® RMK® features an industry-first...forged 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 new 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 new 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

RMK: The True King of the Mountain

Rigidity and rider input: RMK has a rigid suspension and chassis, which makes the sled easier to ride for anyone. It allows the sled to hold any side-hill line and not get pushed out and down the face of a hill the way a flexible suspension does. A rigid suspension and chassis makes the sled more predictable and responsive to rider input which means less rider fatigue.

  • A flexible suspension works against your ability to maintain a side-hill, pushing the sled out and down the face of the slope.
  • tMotion + FlexEdge on the Ski-Doo Summit add flexibility to the suspension and track that make the sled easy to roll over on the sales floor but difficult to perform in technical terrain due to less control on the snow

RMK®: Less Effort. More Control.

The Polaris AXYS RMK has 20% less drive line inertia vs. the Ski-Doo Summit, which means the RMK requires the least amount of effort while giving you the most control and ability to maneuver while riding in the deep snow. Several Polaris innovations drive lower inertia, including:

 

  • QuickDrive Low Inertia Drive System: Designed to make the sled rev quicker for instantaneous lift and reduces rotational inertia by 21% over PRO-RIDE for easier handling and more flickability.
  • 800 H.O. Engine and Legendary Polaris P-85 Clutches: The proven 800 Cleanfire® H.O. Engine delivers +10% increase in power-to-weight ratio and quicker throttle response to generate instantaneous lift. The lightweight crankshaft delivers 25% lower inertia and quicker throttle response. And the proven Polaris P85 Drive Clutches are lightweight and durable, delivering exceptional performance

 

Combine the innovations above with all the other innovations in the AXYS RMK, including the Patented Raised AXYS RMK Chassis, AXYS RMK Rear Suspension, and new Polaris Series 6 2.6” Track, and this is what gives riders the best mountain sled.

RMK®: Now 408 lbs Light

The lightest mountain snowmobile with industry-leading power-to-weight ratio. 51 lbs lighter than the competition.
