2026 YFZ450R SE

Race-bred, high-performance engine

The YFZ450R SE'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 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 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 SE 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 SE 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.

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.

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 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.

Special Edition

This top of the range Special Edition comes in an exclusive colour that gives an even more distinctive look on the track or trail and features quick-release body panels.
