Unleash aggressive, hard-hitting acceleration from your superbike with the RK 520 "Teal Label" Steel Quick Acceleration Chain and Sprocket Kit. This performance drivetrain package converts your heavy factory drivetrain setup into a lightweight 520 conversion.

Paired with a precision-machined steel front sprocket—geared one tooth down from stock for punchier drive out of corners—and a case-hardened C45 steel rear sprocket, this kit delivers extreme longevity without sacrificing track-level responsiveness.
