800 RMK® Assault® 155 NEW 2017

Brand NEW! No hours or miles. Holdover 2017 model with large Polaris Rebate. No trades at this price. Reduced through October to $10,999.

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 new chassis, purpose built for mountain riding, 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.

Rear Suspension

The new lightweight, rigid rear suspension design features revised geometry to control pitch. This improves weight transfer, delivering better control and a more compliant ride. The rigid suspension delivers power directly to the snow. Off-trail, riders will notice improved weight transfer while maintaining the approach angle. On-Trail, riders will notice a more compliant and comfortable ride. The rear suspension features a new rail design that helps lift the rear skid while driving it forward.

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:

Grooved piston for improved durability and engine life

3-stage electronically-controlled exhaust valves for increased power and responsiveness

Electronic oil pump for reduced throttle effort and improved durability

Thermostat with bypass warms up to operating temperature 40% faster and improves durability

High-efficiency intake and exhaust for improved breathability, which increases power

Exclusive VForce Reeds for more power and improved reed life

Lightweight crankshaft that's more durable, 2.5 lbs lighter and has 25% less inertia

This is the same 800 H.O. engine released with great success in the 2015 Polaris RUSH and Switchback models, and has been proven through 100,000+ field testing miles.
