2017 Polaris 800 RMK Assault 155 2.25" Peak
LIGHTEST. STRONGEST MOST FLICKABLE.Features may include:
- 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. 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.
- 3-Stage Electronically-Controlled Exhaust Valves
3-stage electronically-controlled exhaust valves provide improved running quality, crisper throttle response, smoother idle and improved fuel economy. The active feedback for the exhaust valve position provides more accurate fueling in transient situations. These exhaust valves also improve combustion stability, leading to improved durability and engine life.
- Electronic Oil Pump
Electronic oil pump eliminates power-robbing gear drive and provides more precise, improved oil delivery for performance and durability as well as a 35% reduction in throttle effort. Requires no adjustments.
- High-Efficiency Intake and Exhaust
New porous intake duct material and high-flow exhaust system create a better breathing engine package for more power. An all-new silencer provides reduced sound levels. Vforce reeds provide improved performance, throttle response and reed durability.
- VForce Reeds
Provide improved performance, throttle response, and reed durability.
- Lightweight Crankshaft
Lightweight crankshaft weighs 2.5 lbs less, delivering 25% lower inertia and quicker throttle response and spooling. This provides improved acceleration. Designed and engineered specifically for the 800 Cleanfire H.O. Engine for increased durability, this same lightweight crankshaft is used in Polaris Race sleds since the 2013-14 and 2014-15 season, showing it's proven durability.
- 800 H.O. Grooved Piston
New grooved piston was designed specifically for the new 800 HO Cleanfire Engine to increase durability and engine life.
