THE ULTIMATE OFF‑ROADER.

The DNA of the 2‑straight MX & SX Champ YZ250F in a light, great handling machine perfect for tight trails and woods.

Rightfully wrong

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 centralising mass, the under-seat fuel tank and top-mounted air box 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.

CONQUER DIRT
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.

PERFORMANCE
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. Key improvement for 2018 are revised engine internals and ECU which help round out this top performing off-roader.

FRAME & SUSPENSION
The adjustable KYB suspension found on our WRs are considered by many to be the best in the business. Revised front and rear suspension settings for 2018 provides better rider feedback to improve performance and handling. The chassis design centralizes mass for fast, accurate, and agile handling.

 

Powering you into the victorYZone

Yamaha are powering into the 2018 season with the latest WR250F and WR450F, two of the world’s most innovative and successful enduro bikes with a distinguished track record in EnduroGP and Enduro 2. Benefitting from some of the most advanced GP-developed engine and chassis technology, the WR250F and WR450F have the potential to take every rider into the victorYZone.

The WR-F’s unique reverse cylinder head layout features a front facing inlet and rear exiting exhaust that increase intake and exhaust efficiency, thereby enhancing the engine’s linear torque feeling. This innovative design delivers deep reserves of highly controllable and easy-to-use power, giving Yamaha WR450F and WR250F riders a real performance advantage.

The WR-F’s mass centralized design delivers high levels of agility for precise control over all types of terrain – and the advanced aluminium chassis with its class-leading suspension gives excellent handling performance and traction over rock, sand, grass, dirt and mud.

With class-leading durability and legendary Yamaha reliability as standard, the 2018 Yamaha WR450F and WR250F give you winning performance combined with a thrilling ride on any type of terrain.

Loïc Larrieu and WR450F claim outright victory at ISDE 2017

Riding his Outsiders Yamaha Official Enduro Team WR450F, Loïc Larrieu claimed outright victory at the 92nd edition of the International Six Days Enduro that took place in Brive, France between August 28 and September 2.

Attracting over 800 riders from all over the world, this year’s ISDE has been the most important global enduro event of the year. With Larrieu posting the fastest overall times on days one, three and five, he not only secured outright victory for himself, but also made a major contribution to Team France’s World Trophy Team win.

Fighting for 2017 EnduroGP and Enduro 2 titles

Yamaha’s distinguished record in World Enduro is once again underlined this season with Outsiders Yamaha Official Enduro Team Loïc Larrieu taking three consecutive double podium results in EnduroGP. The talented Frenchman is currently the leading 4-stroke rider, and is holding a strong 2nd place on his WR450F in the overall EnduroGP standings after 6 out of 8 Grand Prix.

It’s even closer in Enduro 2, with Yamaha’s Jamie McCanney and his WR250F just 6 points behind the Championship leader. With the GP of Great Britain being held in September, Manxman McCanney is focused on a strong home race performance to reinforce his fight for the World Championship.

With 2 rounds to go there’s everything to play for, and with Larrieu and McCanney confident in their WR-F’s total performance, Yamaha is looking good for another strong result to underline the WR-F’s race winning DNA.

2018 WR250F & WR450F

Developed using our extensive EnduroGP and rally experience, the 2018 Yamaha WR-F models are supplied ready to win straight from the crate. Both the WR250F and WR450F benefit from the latest Yamaha reverse cylinder head technology thafeatures a straight inlet for instant response with strong linear torque. The switch-free electric starter gets you going quickly and easily – very handy when you’re on the side of a hill or in a deep bog – and the enduro-specification radiators come with a lightweight cooling fan that regulates engine temperature even in severe conditions.

WR-F specific features include a wide-ratio transmission – 5-speed on the WR450F and 6-speed on the WR250F – as well as a mass-centralized design with an easy-access top mounted air filter. Both WR-F models also feature an optimised clutch, sealed O-ring chain, 18-inch rear wheel, 7.5 litre fuel tank, side stand and skid plate for ultimate enduro performance.

The list of standard features also includes a bright headlight and LED taillight, and the multi-function LCD enduro race computer gives you the information you need to ensure you stay on time.

Upgrades for 2018

The WR250F boasts a number of new features starting with its revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with 4 titanium valves. A new cylinder head design with reshaped intake and exhaust ports matched to a new shorter intake funnel help to boost top end power, and new camshafts and valve springs were developed to further increase low to mid range power output.

The WR250F also receives a new lighter flat top piston design mated to a new shorter piston pin containing a DLC (diamond like carbon) coating to reduce friction and increase hardness.On the bottom end, the crank has adopted a new balance ratio and new nickel-chromoly steel connecting rod to produce broad, balanced, and predictable power while boosting reliability. These changes are regulated through a revised ECU that sends new 3-D mapping to the fuel injection system to optimise power output and engine feeling as well as improving the rev limiter. For a smoother clutch feeling the clutch push lever is redesigned, and to save weight, the kickstarter mechanism is removed.

Not stopping there, the same bilateral beam frame that is found on the winning YZ250F was added to the WR250F to improve handling. Featuring a central beam that’s 12mm wider at the widest point – as well as newly shaped steel engine brackets and repositioned foot pegs – the 2018 WR250F is an extremely strong and well balanced machine, offering precise handling combined with high stability to attack both technical and high-speed sections.

The industry leading, fully adjustable KYB® spring-type forks and the KYB® rear shock come with optimised settings that work in harmony with the revised frame and engine character. For 2018 the WR250F comes with fresh new graphics, blue rims and an additional side cover.

For 2018 the WR450F benefits from a new ECU that optimises fueling and ignition timing for improved throttle feel and a smoother pick up. Revised suspension settings deliver enhanced handling characteristics, and weight is reduced with the removal of the kickstarter. Also featuring new graphics, blue rims and an additional side cover, the 2018 WR450F brings EnduroGP performance to every rider.
