Yoshimura engine kit parts are, as the name would imply, high performance parts for your Suzuki GSX-R engine. We offer a variety of parts, ranging from aggressive race-proven close ratio transmission gear sets to race-ready camshafts machined from billet cam blanks. These parts are of course very exotic. More important, they can make the difference between a champagne celebration in victory lane… or going home empty handed and wondering what went wrong.

If you want to shave seconds off of your lap times, there is simply no other way to go. By using these strengthened and aggressive parts, not only will you have the time-tested power of Yoshimura in the heart of your GSX-R, but you will also have the tradition of winning that is unparalleled in modern Superbike racing.
