2017 Polaris 800 Switchback PRO-X 137 , RETRO GRAPHICS, ELECTRIC START, REVERSE, REAR STORAGE BAG, WALKER EVANS RESERVOIR SHOCKS, CLEAN AND COOL SLED! 2017 Polaris® 800 Switchback® PRO-X 137 x 1.25" RipSaw II SnowCheck 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. 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 Control Rider Balanced Control gives the rider: Flatter cornering without sacrificing the fun factor; More precise handling in all conditions; Better control in big bumps AND chatter bumps 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. When the trail gets rough or the rider jumps off into the powder, rider balance enables the rider to move back and make the front end light to climb up on top of the snow or the moguls. PRO-XC™ Rear Suspension The completely redesigned geometry of the PRO-XC™ progressive-rate rear suspension is optimized for the best performance and Rider-Balanced Control. Through innovative Polaris engineering and construction, the suspension is both lighter and stronger. 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.
