Rightfully wrong

At Yamaha we’re leaders not followers – so we like to do things our way. And when you take a look at the WR250F’s high-tech ‘reverse’ engine, you’ll see that what may look ‘wrong’ to some people is absolutely right for you!

Revolutionary 250cc 4-stroke engine

Equipped with 4 titanium valves, the revolutionary rear slanted liquid cooled 250cc fuel-injected DOHC 4-stroke engine gets a remapped ECU giving optimized power and an improved rev limiter. For balanced power output with boosted reliability, the bottom end features a revised crank balance ratio and a nickel-chomoly steel con rod.

Reverse cylinder head

The reverse cylinder head has shorter intake and exhaust ports for stronger top end power, while cams and valve springs enhance the low to mid range torque. And for a broad band of balanced performance, the WR250F gets a lightweight flat top piston and hardened DLC-coated low friction piston pin, as well as a crank and con rod.

Compact YZ250F-type aluminium chassis

To optimize the performance gains of the upgraded engine, the WR250F comes with a lightweight YZ250F-based bilateral aluminum beam frame. Its compact design offers an idealized balance of strength and rigidity, giving you the confidence and ability to take full control over all types of extreme terrain, at low and high speeds.

Mass centralization

The mass centralized 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.

Optimized suspension settings

The enduro-specific suspension runs with optimized settings for enhanced control. The KYB® 48mm upside down AOS front forks give speed-sensitive damping for class-leading performance on varied terrain. And at the rear end this high-tech 250cc 4-stroke runs with a link-type Monocross rear suspension system and KYB® shock for ultimate traction.

Smoother enduro clutch and wide-ratio 6-speed transmission

The WR250F's transmission is equipped with a clutch that has been specially developed to handle hour after hour of punishment. The push lever gives even smoother clutch action - and to optimize the stronger performance of the upgraded engine, there's a purpose-built wide ratio 6-speed transmission.

Switch-free electric starter

For easy and reliable starting every time, this next generation enduro bike is equipped with a switch-free ignition system that enables you to fire the engine up with one push of the electric start button. And to reduce the WR250F's overall weight, the kickstart mechanism has been removed.
