2018 Polaris PRO RMK 163 800cc 2.6" Manual

LIGHTEST, STRONGEST, MOST FLICKABLE

The 800 PRO-RMK 163 is part of the lightest, strongest, most flickable deep snow family on the market. The #1 selling mountain snowmobile features the lightweight AXYS chassis and 800 H.O. Cleanfire engine, which deliver the industry's best power-to-weight ratio, giving the rider instantaneous lift and immediate response.

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. The AXYS RMK 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 aluminum overstructure is lightweight and durable for all types of riding. Taller spindles increases clearance to reduce drag.

Rear Suspension

• The 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 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.

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

• Porous intake duct material and high-flow exhaust system create a better breathing engine package for more power. The silencer provides reduced sound levels.

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

• Exhaust side grooves improve oil distribution, Enhanced oiling improves piston & cylinder durability,Design reduces friction & wear, improves efficiency & power

Polaris Series 6 2.6" Track

• The Polaris exclusive Series 6 2.6" track provides the ultimate all mountain performance. The new lightweight track is designed for improved deep snow and hard pack traction and better lift.
