It's all about the race.

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!

      Race bred, high performance engine

      The YFZ450R SE's race-bred 5-valve 4-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.

      Electronic Fuel Injection

      For sharp throttle response the YFZ450R SE is equipped with a 42mm 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.

      Hybrid chassis engineering

      The YFZ450R SE uses a special combination of aluminum 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.

      Assist and slipper clutch

      The YFZ450R SE 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.

      Slick-shifting transmission

      The YFZ450R SE'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.

      Long-travel adjustable suspension

      For reduced unsprung weight, this model is fitted with Kayaba piggyback front shock absorbers and a calibrated rear shock. These adjustable units give refined handling performance to give you the edge over other competitors.

      Ergonomic design

      The YFZ450R SE 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 fenders 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.
