YFZ450R’s sharp-handling chassis and ultra-responsive engine have made it today's number one racing ATV. A race-bred assist and slipper clutch gives more precise control over corner entry speed for quicker lap times - while the uprated engine delivers superfast throttle response and hard-hitting high rpm power for holeshot-winning performance.
Sharp-designed bodywork gives the rider space to shift bodyweight during cornering or hard acceleration. And the light shocks make for super sharp handling.
