2021 WR250F
Learner Approved
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.

FEATURES

New Smartphone Turing
On board WiFi means that you can tune the new WR250F to different track conditions using your smartphone. A downloadable Power Tuner app allows you to make fuelling and ignition timing changes instantly and upload/share them for the ultimate in track-side tuning. The free Yamaha Power Tuner app also allows owners to record ride/race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.

Free Flow Air Filter
The filter element features reduced airflow resistance and intake noise combined with increased reliability. The new filter and the length of the intake funnel contribute to an excellent feeling of traction and linear characteristics during acceleration and deceleration. Plus, dust filtering capability is increased by adding rubber seals to the centre positioning pin.

Engine Map Switch
A bar-mounted dual engine map switch has been adopted and positioned next to the left lever to enable changes in the engine power delivery characteristics mid-race. This switch allows the rider to select one of two engine maps on the fly at the press of a button to cater for changes in the riding environment. This means that when the going gets loose, steep or muddy – high traction can be accessed at the press of a button.

Ligthweight Speed Sensor
A new lightweight front wheel speed sensor connects to a highly precise speed display and with no more speedo drive, makes front wheel changes easier. The system features a pulse wheel and sensor system known for excellent reliability and provides the detailed speed information essential for enduro riding. Display includes low fuel warning light.

Forged Aluminum Sidestand
A lighter and less obtrusive forged aluminium sidestand is positioned to ensure plenty of ground clearance when riding through ruts and the like. The new stand sits higher and the amount it juts out from the chassis is reduced which helps prevent snagging. The weight of the stand has also been reduced by about 100g.

Industry Leading Front And Rear Suspension
WR250F runs the same KYB air-oil-separate closed chamber upside-down front fork as the YZ250F but with model-specific enduro settings to provide stable damping force. This suspension is acknowledged to be the best available on a production dirt bike and responds particularly well during the transition between the compression and rebound strokes. And because the suspension holds up well in the stroke, ground clearance is improved over the outgoing model.

Aluminum Bilateral Beam Frame
WR250F now runs the same bilateral beam frame as the sharp handling current model YZ250F. To achieve a rigidity balance with the amount of flex needed for enduro riding, the engine mount brackets have been altered. The upper-side mounts are the same as on the YZ250F, while two-plate type mounts are used for the front-side mounts. The result contributes to the machine’s excellent feeling of contact with the ground and offers feedback about the riding surface while providing a light feel to the handling.

High Performance Engine
The new WR250F engine features a new high compression forged aluminium piston, revised valve angle and exhaust cam timing with revised balance factor – all based closely on the winning fuel-injected YZ250F design. Its airbox is situated in front of the rider and the fuel tank located at the centre of the bike – a unique configuration that contributes to the bike’s mass centralisation, which plays a pivotal role in achieving light and agile handling.
