YAMAHA YFZ450R

Today's Number One Racing ATV

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 body weight during cornering or hard acceleration. And the light shocks make for super sharp handling.

Advanced Frame

The YFZ450R is motocross ready. The weldless frame is designed from lightweight aluminium, with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralisation. Suspension components and settings reduce weight while providing light, sharp handling and rider comfort.

Advanced Suspension

The front KYB® shocks have Kashima™ coating for smooth operation. 249mm of wheel travel means this racer is up to even the most challenging tracks. The rear swingarm has 279mm of travel for the toughest tracks.

Assist and Slipper Clutch

An assist-and-slipper clutch reduces clutch lever effort for less fatigue while at the same time increasing clutch plate pressure for positive engagement. This clutch system also reduces the engine braking effect, which allows for faster cornering, particularly when downshifting.

Advanced Cylinder Head

The 449cc engine uses titanium five-valve cylinder head technology designed to deliver abundant power in the mid-range to top end, with more hit feeling right off idle. The higher compression ratio further improves overall engine performance.

Aggressive Bodywork

Bodywork is designed for great ergonomics and rider comfort, with more room to hang off in the corners, and the seat shape is padded in just the right places to improve lap times. Body panels come off easily without tools for service; there’s no need to remove the battery.

Race Ergonomics

The two sets of holes in the handlebar crown and the eccentric clamps allow a rider to choose the standard setting, 10mm or 20mm forward, or 10mm back. Footpegs are a generous 66mm wide, something riders will appreciate every time they want to get up on the pegs.

Wide Track and Maxxis Tyres

Wheels are set motocross-spec wide, near the maximum allowable 1270mm, for great cornering speed. Maxxis® tyres help provide excellent handling and control. At 508mm in the rear and 533mm in the front, they provide better ground clearance than the competition.
