MX CHAMPIONSHIPS MADE EASY

From the manufacturer who started the 450 cubic centimeter sport TV performance craze comes the 2011 YFZ450R. With true long-travel adjustable suspension, potent powerplant, aluminum hybrid frame and a bevy of other racer-friendly features, it really is the only choice for ATV MXers—amateur or pro. Since we started it, makes sense we'd be first to the finish, no?
