WR250F
Yamaha WR250F for Sale at Ultimate Yamaha Springwood in Springwood, QLD | Specifications and Review Information
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.
Speed Sensitive Suspension
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.
Aluminium Bilateral Beam Frame
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.
Reverse Cylinder Head
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.
Mass Centralisation
The mass centralised design is a concept we pioneered, and it's what gives the WR250F the edge over the competition. By locating major components like the fuel tank, cylinder and exhaust system close to the centre of the chassis, we've been able to create an enduro bike whose agile handling gives the Yamaha rider a real advantage - all day long.
Enduro Clutch
The WR250F's transmission is equipped with a newly developed clutch that has been specially developed to handle hour after hour of punishment. And to optimise the performance of the new fuel injected engine, there's a purpose-built wide ratio 6-speed transmission.
Optional Power Tuner
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.
