70th Anniversary Edition bodywork

No other bike gets as much attention as this special 70th Anniversary Edition! Its exclusive white and red livery pays homage to Yamaha's rich racing history and celebrates the spirit of always challenging for the win. It's the ultimate edition of this high-tech 250cc 4-stroke.

Bilateral aluminium frame

The latest generation YZ250F uses the same frame design as the MXGP race winning YZ450F. This lightweight bilateral aluminium frame's improved handling enables you to corner faster and smoother. The lower centre of gravity and reduced weight make the YZ250F more agile than ever and the balance of rigidity and YZ250F-speci c engine mounts give plenty of feel and feedback.

Optimised rider ergonomics

The rider triangle accommodates riders of varying sizes and physiques offering better ergonomics with enhanced rider mobility and increased controllability. And the side panels give a tighter and lighter look, while the front fender improves air ow to the radiators for consistent cooling.

Responsive top-end power

The YZ250F is already regarded as one of the most competitive and responsive 250cc 4-stroke engines in the low to mid rpm range. The latest rear duct air management system together with the ECU boost the top-end engine performance, making this Motocross Grand Prix race winning machine even more competitive for every rider.

Efficient air-management

The high-rpm engine performance has been lauded by the press and owners alike, and the body width is kept to a minimum by the efficient air-management system that channels fresh air from the rear through the spaces between the fuel tank, frame, seat and side panels. When it reaches the lightweight airbox the air is pre-cleaned by a vortex that throws particles to the side, reducing air cleaner clogging and making routine maintenance easier.

Revised suspension settings

The YZ250F's KYB front forks are widely regarded as being amongst the best in class and the latest generation bike features revised fork settings as well as a hand adjustable compression damping adjuster. The link-type Monocross rear suspension and KYB shock with the latest suspension linkage for increased traction on corner exit runs optimised settings and the Power Tuner App contains useful suspension setting data for quick and accurate manual adjustments.</span>
