XG750R : Harley Davidson avec Vance & Hines pour créer un flat tracker pour les courses Dirt Track


Harley Davidson a frappé un grand coup en dévoilant la XG750R, son premier flat tracker depuis 44 ans. La monture partage sa motorisation, un V-Twin Revolution X, avec la Street 750 pour laquelle il a été développé. Mais préparé pour la course par le team Vance & Hines, le bi-cylindre en V à 60° développe 110 chevaux et avec refroidissement liquide, qui équipe la Street 750. Donc cette moto type flat tracker a été présenté fin mai à l’AMA PRO SPRINGFIELD MILE. La constructeur de Milwaukee a donc présenter son nouveau XG750R, un modèle qui ne sera pas disponible en concession mais destiné aux courses sur terre américaines. En ce moment, il y a le rassemblement Wheels and Waves à Biarritz, et de fait Harley Davidson est partenaire de l’event. Mais d’abord retrouvons des photos de la belle mécanique au bord de la mer à la Cité de l’Ocean ! :D

Design de Harley Davidson XG750R

« Après des décennies de succès en compétition Flat track acquis avec le Harley-Davidson XR750, nous savions qu’il était temps de réfléchir à une nouvelle génération de machines Harley-Davidson pour participer à une des compétitions de sports mécaniques les plus relevées et appréciées du public. » - Kris Schoonover, Manager du programme

The Harley-Davidson XR-750 is a racing motorcycle made by Harley-Davidson since 1970, primarily for dirt track racing, but also for road racing in the XRTT variant. The XR-750 was designed in response to a 1969 change in AMA Grand National Championship rules that leveled the playing field for makes other than Harley-Davidson, allowing Japanese and British motorcycles to outperform the previously dominant Harley-Davidson KR race bike.[1] The XR-750 went on to win the most races in the history of American Motorcyclist Association (AMA) racing.

Flat track racing?

Pour rappel, le Flat Track consiste à rouler à toute fond sur une piste ovale ‘dirt track’ devant des spectateurs aussi passionnés que les pilotes qui se lancent sur la piste. Une discipline vieille comme le monde de la moto qui galvanise depuis des lustres par son principe simple – tourner en rond, à fond – et le niveau d’engagement demandé aux pilotes.

Flat Track Racing


Flat Track racing has brought H-D Screamin’ Eagle Factory Racer Davis Fisher fond memories and an unbreakable bond with his father Rex. Watch to see how proud Rex is of Davis for following in his father’s footsteps.

Flat track racing looks similar to Speedway racing but is in no way related. Flat track motorcycles can have either two-stroke or four-stroke engines in amateur competition. Four-stroke motorcycles dominate professional competition and depending on the venue, can be single or multi-cylinder. Flat track bikes have front and rear suspension, and rear brakes. The brakes are what make it completely distinct from speedway, as the brakes allow for a different cornering technique. Successful riders will often move to road racing, which is considerably more lucrative. Many top American riders in Grand Prix motorcycle racing began their racing careers as flat track racers.

En France, le mouvement moto custom n’a cessé de rendre hommage au courant Café Racer. En passe de supplanter ce dernier, le Flat Track arrive en force. Ce n’est d’ailleurs pas pour rien que l’on retrouvera une course de ce type, « El Rollo » à San Sebastian, il y eu ce mercredi 8 juin, en marge du Wheels and Waves 2016, une ode à la moto custom sous forme de festival, se tenant à Biarritz depuis 4 ans déjà.

English summary

Next Generation, Liquid-Cooled Harley-Davidson XG750R Flat Track Bike Breaks Cover at AMA Pro Springfield Mile

MILWAUKEE (May 26, 2016) – A new-generation Harley-Davidson flat-track motorcycle is ready to race. The Harley-Davidson Screamin’ Eagle Factory Team is unleashing the XG750R, its first all-new flat track race bike in 44 years, to battle in fierce, adrenaline-filled competition on dirt ovals across the U.S. The XG750R will make its official competition debut Sunday, May 29, at the AMA Pro Flat Track Springfield Mile in Illinois.

Powered by the fuel-injected, liquid-cooled Harley-Davidson Revolution X V-Twin engine, the XG750R will be raced by Factory Team rider Davis Fisher on the AMA Pro Harley-Davidson GNC1 presented by Vance & Hines flat track series. The new XG750R motorcycle is strictly for race competition and will not be offered for sale at this time.

The new flat tracker is powered by the 750cc Revolution X™ V-Twin engine designed for the Harley-Davidson Street 750, a motorcycle built for maximum urban maneuverability with rebellious Dark Custom attitude. Tuned for the track, this modified Revolution X engine will power the new XG750R in the extreme heat of competition as it fights to be first to the finish line.

The race-modified Revolution X engine and a racing frame for the XG750R were developed by Vance & Hines Motorsports. Vance & Hines also is the partner for the factory Harley-Davidson Screamin’ Eagle/Vance & Hines drag racing program where V-Rod motorcycles have won eight of the past 12 NHRA Pro Stock Motorcycle drag racing championships.

“After decades of flat-track racing success behind the Harley-Davidson XR750 flat track motorcycle, we knew it was time to develop the next-generation Harley-Davidson to compete in one of the best spectator racing sports out there today.”


Fisher, in his first season racing with the Harley-Davidson Screamin’ Eagle Factory Team and a rookie on the GNC1 series, will be the first racer aboard the XG750R. The 18-year-old racer from Warren, Ore., won the 2015 AMA Pro GNC2 championship.


“We wanted a young rider with plenty of raw ability for the XG750R program, and Davis proved himself in the GNC2 class. We are excited to have the opportunity to bring an emerging talent like Davis up to the GNC1 series to develop the new bike alongside an experienced champion like Brad Baker.”


Harley-Davidson Screamin’ Eagle Factory Team rider Brad Baker, 23 years old and the 2013 AMA Pro Grand National Champion, will continue to race aboard the proven Harley-Davidson XR750 motorcycle while Fisher races the XG750R through its developmental stage.


“The XG750R has shown great potential in testing and the first few races this season. But as with any new racing motorcycle, there will be work to do. We’re excited to continue testing the XG750R in real world competition, and as we make our way through the season, we will evaluate the performance of the bike and our factory riders to see if Baker might switch to the new bike.”


- Kris Schoonover, Harley-Davidson racing manager
