RUSH. THE SLED THAT DEFINES TRAIL PERFORMANCE. Driven by our class-leading 600 cc Cleanfire® engine, the Rush receives refinement for 2012 to help make it even more capable out on the trail. Upgraded with the all-new race proven IFS for flatter cornering and easier steering. In addition, a revised front torque arm position helps for flatter cornering while the progressive-rate rear suspension puts the rider in control rather than letting the terrain dictate how hard they can ride.
