With DNA lifted straight out of our championship winning YZ250F, this model is a precision instrument for single track surgery.
If you think you need a big bore motor to go quick on the trails – think again. One spin on the WR250F is enough to convince most riders that the instant delivery from the reverse fed race-inspired engine combined with super sharp handling is the quickest way through the forest.
WR250F’s industry leading twin chamber speed sensitive KYB forks and matching rear shock deliver an unbeatable package when the trails get technical.
This motorcycle is not designed or intended for continuous "on road" use. Yamaha WR models have been modified to enable ADR compliance and registration only to support their intended use as a competition or serious off road use enduro motorcycle. Please discuss intended use with your Yamaha dealer prior to purchase.

The WR250F's innovative reverse cylinder head offers many advantages over a conventional design. These include increased intake and exhaust efficiency, as well as enhanced mass centralisation thanks to the use of a top-mounted air filter and underseat fuel tank. Yamaha's engineers have taken this cutting-edge technology to the next level, and developed a new reverse cylinder head that offers even stronger mid to high rpm pulling power.
Using feedback from our factory teams, Yamaha has been able to fine-tune the frame in order to ensure that WR250F riders are able to fully exploit the increased engine performance of the uprated model. The new frame is around 12mm wider in the area behind the swingarm pivot point, and this increased torsional rigidity ensures a higher degree of handling stability.
Increased rideability and comfort have been achieved on the WR250F through a number of revisions to the front and rear suspension. The class-leading Air Oil Separate (AOS) KYB front forks feature slightly reduced oil capacity and new factory suspension settings to give improved rider feedback and improved stability in ruts, bumps and corners.
Riders of all abilities can also use the optional Yamaha Power Tuner to adjust the WR250F’s power characteristics. This compact device plugs straight into the bike without the need for a PC, and enables the rider or mechanic to fine-tune the engine performance in seconds to suit the track conditions.
