yamaha 2021 YZ250F

//RRP £7,699

Developed using the very latest technology from the Yamaha’s race-winning MX2 and SX factory bikes, the new YZ250F is sharper, quicker and smoother – giving you the performance and the confidence that you need to succeed.

Tune. Race. Win.

As soon as the gate drops you can feel the YZ250F’s new engine with its stronger low to mid-range performance thanks to the revised exhaust camshaft, lighter piston and longer con rod – while an all-new cylinder head with an improved intake design gives a harder-hitting top end. And by using your smartphone with the Power Tuner app you can select the ideal power profile for optimum race performance in all conditions.

The latest chassis feels sharper and lighter than ever thanks to the refined rigidity of the aluminium beam frame which features all-new flex characteristics, and revised suspension settings – giving you the ultimate combination of precise cornering performance and handling stability. And the new generation Icon Blue body with coordinated front and side plates gives a radical and fresh look. Tune. Race. Win.
