9207 KM 2016 Polaris® 800 Switchback PRO-S™ SMOOTHEST RIDING. MOST VERSATILE. Features may include: AXYS® Chassis The AXYS® chassis features 93% new parts, including a carbon-fiber overstructure and aluminum handlebars on SnowCheck Select or Limited Edition models and an aluminum overstructure on standard models. The chassis structure and design makes it possible to change the rider positioning, centralize vehicle mass, redesign the rear suspension, add more power, remove weight, and evolve the rider’s riding experience. In short, it is the key to delivering rider-balanced control, unrivaled acceleration, and rider-centric comfort. Rider Balanced Positioning On the AXYS® chassis, the rider is moved forward to a more balanced position. The rider’s hands are moved 4.5” forward, the feet are 2” forward, the knees are 4.5” forward, and the seat is 4.5” forward. In the neutral riding position, the AXYS® platform provides bite for flatter, positive cornering. Active Pitch Control™ The PRO-XC™ suspension delivers Active Pitch Control™ which controls the pitch by suspension geometry and not simply by a high spring rate. This makes the sled less sensitive to adjustment while allowing optimal weight transfer. Lightweight When developing the AXYS® platform, Polaris engineers minimized weight throughout the sled without compromising strength. The 800 Switchback PRO-S is more than 35 pounds lighter than the previous chassis and weighs approximately 40 lb. less than a competitive crossover model. 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.
