Features
Race-bred high-performance engine
The YFZ450R's race-bred five-valve four-stroke 450cc engine features a compression ratio of 11.8:1 and high-performance camshafts for instant throttle response and race-winning high rpm power. The air induction system gives high fuel efficiency, reduced exhaust emissions and increased durability.
Slick-shifting transmission
The YFZ450R's 5-speed transmission is one of the slickest shifting systems in its class, and is fitted with an assist and slipper clutch – the first time this race-developed technology has been used in this category. The system makes shifting between gears even easier for quicker lap times and reduced fatigue.
Assist and slipper clutch
The YFZ450R is the first ATV in its class to feature an assist and slipper clutch that's designed to partially disengage when you're downshifting quickly for a turn. By virtually eliminating the effects of engine braking, the slipper clutch allows the rider to control corner entry speeds using the brakes for enhanced control and reduced lap times.
Long travel adjustable suspension
For reduced unsprung weight this model is fitted with KYB piggyback front shock absorbers and a calibrated rear shock. These adjustable units give refined handling performance to give you the edge over other competitors.
Hybrid chassis engineering
The YFZ450R uses a special combination of aluminium and steel in its frame and swingarm construction, and this innovative hybrid chassis design offers a winning combination of low weight together with outstanding strength and an excellent rigidity balance.
Electronic Fuel Injection
For sharp throttle response, the YFZ450R is equipped with a 42 mm Mikuni throttle body, which includes an ISC (Idle Speed Control) system for easy and reliable starting and warming up. This advanced system delivers instantaneous pick-up and contributes towards reduced emissions.
Ergonomic design
The YFZ450R is designed to work in perfect harmony with the rider for improved performance on the track and added comfort on the trail. The front and rear mudguards are designed to give more space around the rider for easy weight shifting when cornering or accelerating – and the heel guards are also relocated further back.

It's all about the race.
The YFZ450R is a true, zero compromise sport machine. Its sharp-handling chassis and ultra-responsive 50cc engine have made it stand among today's number one racing ATVs.
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!
