YFZ450R/SE

Serious racers will tell you that the Yamaha YFZ450R is the clear favourite with winning riders. Its sharp-handling chassis and ultra-responsive 450cc engine have made it today's number one racing ATV. Nothing else comes close

A race-bred assist and slipper clutch gives more precise control over corner entry speed for quicker lap times - while the race-bred engine delivers superfast throttle response and hard-hitting high rpm power for holeshot-winning performance.

Sharp-designed bodywork gives the rider space to shift the bodyweight during cornering or hard acceleration. And the lightweight piggyback shocks make for razor-sharp handling!
