Yoshimura GSX-R Kit Parts and Yoshimura Race Shop


Yoshimura’s range of Racing “Kit Parts” offers the quality and performance that the name Yoshimura has become known for. Kit Parts is a euphemism for highly specialized custom parts designed for racing. Price is not a consideration with Kit Parts - performance is the only criteria.

Although exotic, one can expect reliability equal to or far surpassing OEM parts. Yoshimura Kit Parts are the same race proven items used by Team Yoshimura Suzuki Road Racing and others in competition. These are the same parts that have been on Yoshimura GSX-R’s, which have set virtually every record in American Superbike Racing, over the last 55 years.

Hard Parts

Years ago we decided that to win we needed to manufacture our own components. Stock wasn't an option, and handmade "works" parts were inconsistent in specification and quality at times. As a result, about 25 years ago we started building all of our own CNC parts in-house. Since then, we have added numerous products such as fender eliminator kits, case savers, chassis protectors, etc. As with all of our products, Yoshimura hard parts are unparalleled in quality and performance.

Engine Management Systems

Yoshimura has been a leadership company in EFI management for years. By the time all these other guys figure out what we already know - the race will be over. Check out our race proven PIM 2 units for off-road racing applications, and our Em Pro for road racing applications. They have a long track record of performance, durability, and ease of use.

Engine Services

At Yoshimura, we have been building four-stroke racing engines for over 50 years. We understand that your engine is the sum of many parts. We do not simply throw a big cam in, pop up the compression, and create a time bomb. Depending on which stage of engine modification you choose, we build power at self-sustaining, balanced levels.
