The 2011 MY YZ450F is Yamaha's top off-road performer, a bike incorporating a lot of works-developed technologies and components. Built with the racing program experience, the YZ450F is a bike for true racers. It sports explosive power and incredible maneuverability, plus ergonomics specially formulated for competition use. The weight optimization brings everything closer to the center of the bike, into the newly-revised bilateral beam aluminium frame. The suspension is also all-new for this model year.
