2017 Yamaha WR250F on www.Totalmotorcycle.com
The Ultimate Off-Roader...
The DNA of the 2-straight MX & SX Champ YZ250F in a light, great handling bike perfect for enduro riding through tight trails and woods.
At Yamaha we've always liked to do things our way. Being different is what makes our bikes so special. 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 centralizing mass, the underseat fuel tank and top-mounted airbox design give you ultra-light handling performance.
Featuring a 6-speed gearbox with a special enduro clutch, and running with
class-leading suspension, the electric-start WR250F is taking Yamaha back
to the front.
We've taken our revolutionary YZ four stroke motocross technology and applied it to the enduro world. Rearward slanted engine, reversed cylinder, forward mounted fuel injection and a compact chassis are just some of the key features found on the WR250F. Delivering light, agile handling on tight trails, the WR is also a great choice for the experienced recreational rider too.

1. Competition Ready
Revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with 4 titanium valves based on the YZ250F, with an added sixth gear and wide ratio transmission, among other modifications, make it perfect for Enduro competition.
2. Nimble Chassis
Nearly the same bilateral beam frame that is found on the championship winning YZ250F is used on the WR250F. It places
the engine and fuel tank close to the center mass of the bike for extremely light and nimble handling character.
3. Fuel Injection
A Keihin® 44mm throttle body fuel injection system is tuned for Enduro riding ensures smooth throttle response and easy starting in
nearly all conditions. Plus the electric start button reduces rider fatigue.
4. Advanced Suspension
Industry leading fully-adjustable KYB® spring-type forks with speed sensitive damping and a KYB® rear shock, each tuned with Endurospecific settings.
5. Enduro- Specific Features
With a 2 gallon fuel tank, multi-function Enduro computer, 18-inch rear wheel, O-ring chain, skid plate and Enduro spec tires, the
WR250F is ready to win right out of the box.
The latest generation YZ250F engine is the inspiration for the WR power plant. A forward mounted 44 mm fuel injection system supplies fuel to the 4-valve cylinder head, while the wrap around exhaust removes the spent charge and centralizes mass at the same time. A couple of items you won't find on a YZ250F is the WR's 6-speed transmission, electric starting and radiator cooling fan.
///Frame & Suspension
The adjustable KYB suspension found on our YZs is considered by many to be
the best in the biz. So, we have added them as well as our Bilateral Beam
all aluminum frame to the WR. Adjustable KYB "SSS" forks and piggyback
rear shock allow you to tailor suspension settings to match weight, riding
style and terrain. While the chassis design centralizes mass for fast, accurate,

48mm, adjustable, inverted, Kayaba "SSS" cartridge fork offers 310mm (12.2") of wheel travel.
valving & settings are designed for enduro racing / riding
front fork adjustments include: 20-way compression damping and 20-way rebound damping
optional fork springs are available through Genuine Yamaha parts.
Fork features a twin-chamber, "Speed Sensitive System" design meaning the damper unit is in a separate structure (completely separated air & oil chambers) which prevents aerated fork oil from entering the inner damper assembly & degrading its damping abilities. Since the inner damper is pressurized, it also eliminates bubbles forming in the oil.
Fork also features a Transfer Control Valve (TCV).
TCV enhances damping from mid to full stroke & improves bottoming characteristics
TCV offers more precise control throughout the full suspension stroke
TCV is located on the upside of the spring & its function is controlled by piston speed, not piston position, hence the term "Speed Sensitive System fork".
