The 2010 MY KFX 450R is ready to race out of the box, sporting a high-tech aluminium frame, long front A-arms, adjustable suspensions and a 5-speed transmission with reverse. Under the hood you will find a 449cc liquid-cooled 4-stroke single built with race-grade parts. Forged pistons, titanium valves, a titanium exhaust and smart engine tuning for strong acceleration with minimal wheelspin are all helping you get on the podium.
Cue dual-rate springs, petal rotors, the possibility to use other MX handlebars, reinforced rims, quick-remove headlights for racing events compliance and even an optional kick-starter for less weight when racing priorities demand it.
