RK Chain Aluminum Race Chain and Sprocket Kit

The RK Chain Aluminum Race Chain and Sprocket Kit is a complete motorcycle drive kit. It gives sportbike and track riders quicker acceleration by combining race-oriented gearing with a lightweight aluminum rear sprocket. Each kit pairs a premium sealed racing chain with matched front and rear sprockets, so it works as a chain and sprocket set, a drivetrain upgrade or a race conversion kit.

Key Features:

• Sealed racing chain: RK's lightweight sealed-ring performance chain (RX, XW-ring or similar series, depending on the application) comes in a gold finish.
• Aluminum rear sprocket: The rear sprocket is 7075-T6511 aluminum with a black hard-anodized finish. It reduces rotating mass compared with a steel sprocket.
• Hardened steel front sprocket: The front sprocket is C45 steel, case hardened and quenched for wear resistance.
• Race gearing: The kit includes a front sprocket one tooth smaller than stock. This helps the bike reach its redline quickly in every gear.
• Street and track use: The kit is meant to improve acceleration without giving up normal ride and handling.

Lighter rotating mass and shorter gearing give quicker starts and sharper throttle response. That makes the kit a good choice for racing, track days and spirited street riding.
