Immediate Response 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 maneuvarability. LIGHTWEIGHT: 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 new 800 H.O. Cleanfire® Engine, new Polaris-exclusive track designs and the new raised chassis. POWDERTRAC™ RUNNING BOARDS: 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. For 2016, we continued to refine and improve the running boards. There is now additional open space at the back of the boards by the rear pad to reduce snow build up.
