Renthal Rear Sprocket, Aluminum, 50-Tooth, Purple (112U-520-50GEPE)

Upgrade your motorcycle’s final-drive performance with the Renthal 112U-520-50GEPE rear sprocket. CNC-machined from high-strength 7075-T6 aluminum, this purple sprocket is engineered for riders seeking reduced unsprung weight, efficient power transfer, and dependable durability. It is designed for compatible Kawasaki and Suzuki applications and provides a precision-focused alternative to conventional steel sprockets.

The Renthal rear sprocket uses a computer-aided ultra-light design to help minimize unsprung weight without sacrificing strength. Its 7075-T6 aluminum construction is approximately 33% lighter than steel, helping reduce rotating mass and improve power transfer through the drivetrain. CNC machining delivers accurate tooth geometry and a consistent, high-quality finish for reliable performance in demanding riding conditions.

A specially engineered tooth profile allows the chain to roll smoothly onto and off the sprocket. This design helps promote longer chain and sprocket wear, reduced drivetrain noise, and efficient power delivery. The 50-tooth gearing configuration can also be used to tailor acceleration and overall final-drive characteristics when paired with the appropriate chain and front sprocket.

The Renthal 112U-520-50GEPE combines lightweight construction, durable materials, and precise machining in a performance-oriented rear sprocket package. Verify your motorcycle’s fitment, chain size, and gearing requirements before installation. Follow the motorcycle manufacturer’s installation procedures and inspect the chain and related drivetrain components during service.
