Yoshimura-tuned Suzukis have ruled AMA Superbike racing since the late ’70s, starting with Wes Cooley and continuing through the Kevin Schwantz, Jamie James, Mat Mladin, Ben Spies and now Blake Young eras. Yoshimura’s red-rectangle logo has become synonymous with quick Gixxers, a relationship that’s celebrated with this new series of limited-edition, Yoshimura-equipped GSX-Rs. But unlike those storied Superbike racers, these are Yoshimura replicas in appearance only. With the exception of freer-breathing (but still EPA-compliant) R-77 carbon-fiber slip-on exhausts, the engines and drivetrains remain factory-stock. Cosmetic upgrades, on the other hand, are many.
