The 600 PRO-RMK 155 snowmobile is part of the lightest, strongest, most flickable family of sleds on the market - the PRO-RMK. The 600 engine is perfect for riders that want a high performance sled with instant acceleration.
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.
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.
This liquid-cooled Cleanfire® engine with semi-direct injection (SDI) deliver outstanding throttle response and instant acceleration. These powerful, efficient engines start easily and reliably and they calibrate automatically as the temperature and elevation change. These engines deliver impressive fuel economy in real-world riding situations, which, for Polaris riders, means aggressive, up-tempo riding, not low-rev lab conditions. In the AXYS® chassis, the 600 engine features lightweight integrated mounts, electronic oil pump and bypass thermostat.
The QuickDrive™ Low Inertia System is designed to make the sled rev quicker for instantaneous lift and reduces rotational inertia by 21% for easier handling and flickability.Not simply a belt-drive, it is a complete lightweight drive system — featuring an extruded drive shaft, lightweight brake, RMK-specific brake caliper and of course the most visible piece of the system — a maintenance-free belt drive that requires no oil or tensioner system. The complete system reduces rotational inertia by 21% which means 5lb. less effort when carving.
PRO-RMKs come standard with Walker Evans® Monotube Shocks. During SnowCheck, there is a choice of premium Walker Evans® Piggyback Clicker Shocks or the Walker Evans® Monotube Shocks. The Walker Evans® Piggyback Clicker Shocks with compression adjusters and remote reservoirs offers the best performance across the broadest range of conditions. The Walker Evans® Monotube Impact-Extruded Shocks are the lightest weight shock option from Polaris for those riders counting ounces. The one-piece, simple design is lightweight yet durable. NEW updates for MY18 for the Monotube Shocks include all new valving with “Hi Flow” Walker Evans pistons on the Front Suspension and Rear Track Shock that delivers less bottoming in the big bumps while maintaining a supple initial feel on the trail.
Polaris snowmobiles are the lightest sleds on the mountain. Polaris®mountain sleds have always been light AND rigid, and Polaris has added strength & durability while reducing weight on the RMK® AXYS® platform. Polaris uses design optimization software to analyze the loads and stress points for various systems and components of the snowmobile which allows the team to design lightweight yet durable snowmobiles. Providing riders with instantaneous lift, Polaris sleds help riders get up on top of the snow faster due to the lighter weight, increase in power from the 800 H.O. Cleanfire® Engine, Polaris-exclusive track designs and the raised chassis.
The PowderTrac™ running boards have been developed for maximum snow clean out and maximum strength. Built from extruded aluminum with bonded cast lugs, they boast an open area of over 50% and integrated traction that is machined in for sure footed performance. There is now additional open space at the back of the boards by the rear pad to reduce snow build up.
All models built on the AXYS® platform feature standard LED headlights. LED headlights deliver the industry’s best lighting:
