Yoshimura Research and Development of America, a leader in both motorcycle racing and high performance exhaust manufacturing is beginning a new chapter by offering previously unobtainable Suzuki GSX-R road racing parts. These are the same parts used by past and present Rockstar Makita Suzuki riders Ben Spies, Mat Mladin, Blake Young and Tommy Hayden within AMA Superbike racing. Additionally, Yoshimura will know offer engine building services for both street and off-road motorcycles. This new division will be marketed as Yoshimura Race Shop (YRS).

Perhaps the biggest question in regards to Yosh’s new venture is, what took them so long? And the answer isn’t quite as simple as you’d think. You see, at its core, Yoshimura is all about racing. It’s why company founder, Hideo “Pops” Yoshimura first started the company and why today it has amassed more championships than any other aftermarket performance tuner – an amazing 33 and counting. But now that American racing has become more production-based they’ve decided to begin offering these parts to all.

So what kind of performance goodies are YRS offering? Everything.

In the powertrain department YRS will offer high compression pistons, camshafts, clutch and transmission parts. In terms of chassis, YRS will stock suspension linkage kits, fork tube extenders, swingarm pivot shims and even a kit Showa racing shock absorber!

YRS will also be selling its EM Pro engine management software, race-style stator and racing wiring harness. Not to mention offering engine case savers, chassis protectors and attractive high-grade aluminum engine and oil filler plugs, axle blocks and steering stem nuts.

All of the parts are manufactured in the United States or Japan, ensuring the highest quality. Last year, we tested one its Suzuki GSX-R1000 exhausts and were blown away by the pipes' craftsmanship and overall fit and finish.

Currently all engine, chassis and electronic parts are available for late-model Suzuki GSX-Rs but YRS is working to produce the same type of parts for other late model high-performance sportbikes and off-road and motocross bikes. Furthermore all of the road racing parts currently offered are homologated and approved for use in the AMA Pro Road Racing series.

YRS engine building services will allow an enthusiast or racer to purchase the exact same engine as used inside Mat Mladin’s No. 7 Rockstar Makita Suzuki GSX-R1000. Additionally engines can be built to any specification based on the user’s needs and how deep they’re pockets are. Also introduced is a new line of branded apparel and road racing suits, manufactured by Pilot leathers.

All parts can be purchased directly from Yoshimura or at your local Parts Unlimited dealer including Motorcycle-Superstore. Check out YRS for more information. And check back in a few weeks for reviews of some of its previously unobtainable performance parts.
