At Yamaha, we’ve always liked to do things our way. Being different is what makes our bikes so unique. And when you take a look at the WR250F’s high-tech ‘reverse’ engine you can see that what may look wrong to some people is right for us! The WR250F is a gamechanger.
A front facing inlet and tuneable fuel-injection system deliver an instant hit of power. And by centralising mass, the under the seat fuel tank and top-mounted airbox design give you ultra-light handling performance. Featuring a 6-speed gearbox with a first enduro clutch, and running with class-leading suspension, the electric-start WR250F is taking Yamaha back to the front.
