The 800 RUSH® PRO-X is a SnowCheck Exclusive model for riders who want ultimate big bump control. It is the perfect snowmobile for riders that need to dominate ditches and moguls, and those who ride primarily standing up. Its powerful, proven 800 H.O. Cleanfire® engine, AXYS® Chassis, and Walker Evans® Needle Shocks deliver Rider-Balanced™ Control, Unrivaled Acceleration, and Rider Centric Comfort. Rider Balanced Control 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. How did we get there? Polaris: Put the rider in the right location on the sled; Centralized vehicle mass; Optimized the suspension geometry to better control pitch. 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.
