Packed with “out‑of‑the‑box” off‑road features ‑‑ perfect for enduros and off‑road thrill seekers.

Rightfully wrong

Equipped with the most advanced engine and chassis technology ever developed for a Yamaha dirt bike, the WR450F is ready to shake up the off road world.

Built for serious enduro racers as well as long distance rally riders and experienced recreational riders, the latest generation WR-F produces strong and linear torque that gives you outstanding performance together with a high level of controllability.

For lightweight handling this high-tech off road bike is equipped with a compact, mass centralised chassis – and with its wide ratio 5-speed transmission, latest KYB® suspension and main switchless electric start, the Yamaha WR450F is ready to win.

CONQUER DIRT
The WR450F utilizes many of the same features as our championship winning YZ450F. Yamaha’s engineers draw on the highest level of competition for inspiration & innovations. From engine design to suspension to exterior styling, the racing performance & presence of our legendary YZ models can be found in our entire off road competition model lineup.

POWER
The WR450F utilizes our latest championship winning YZ450F rearward slanted, reverse fuel injected engine design. Tuning has been revised to suit enduro style use. The WR450F produces serious power for those riders who are serious about winning. And with our optional GYTR Power Tuner and special kit ECU, the machine can be quickly “tuned” to suit riding conditions and rider preferences. Click here for YZ Power Tuner suggested settings.

FRAME
Compact Bilateral Beam aluminum frame centralizes mass for exceptional handling & maneuverability, especially in tight technical situations.

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.
