2026 YZ250F

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-specific 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 airflow 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 praised 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 sidepanels. 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.

Modified exhaust to meet FIM regulations

The YZ250F's exhaust system has been modified to meet the latest FIM noise regulations, while retaining the bike's renowned controllable power characteristics and ride.

Low friction cam chain

The YZ250F's reverse-head engine is equipped with a low friction cam chain that is designed to accommodate the increased top-end power.

Lightweight components

Yamaha's designers have focused on saving weight wherever possible while maintaining the YZ250F's reliability and durability. Significant weight reductions have been made to improve power to weight and handling capability.

Advanced traction control and launch control syste

The 2026 YZ250F is equipped with the latest electronic technologies that give you the highest levels of controllability. The launch control enables you to set your maximum engine launch rpm when the gate drops for holeshot winning performance. And the traction control system offers two levels of assistance as well as an OFF function.

ECU lock anti-theft device

An ECU lock function enables the rider to lock the bike via a smartphone, and the engine can’t be started again until the password is correctly entered on the phone. The function provides a great anti-theft system for a bike with no physical key.
