Renthal Rear Sprocket, Aluminum, 50-Tooth, Black for Honda and Yamaha (150U-520-50GBBK)

The Renthal 150U-520-50GBBK rear sprocket is engineered for riders who want reduced unsprung weight, efficient power transfer, and dependable drivetrain performance. CNC-machined rather than stamped, this 50-tooth sprocket features a computer-aided ultra-light design that helps reduce rotating mass while maintaining the strength required for demanding riding conditions. Its black finish provides a clean, durable appearance that complements a wide range of Honda and Yamaha applications.
Manufactured from high-strength, specially enhanced 7075-T6 aluminum, the Renthal rear sprocket is approximately 33% lighter than a comparable steel sprocket. The weight savings can help improve acceleration and handling response without sacrificing the durability needed for consistent chain and sprocket performance. The precisely machined construction also supports accurate fitment and reliable power delivery through the drivetrain.
A specially developed tooth profile allows the chain to roll smoothly on and off the sprocket. This design helps promote longer chain and sprocket wear, reduce operating noise, and transfer power efficiently. With its 50-tooth configuration, black finish, and Honda and Yamaha compatibility, the Renthal 150U-520-50GBBK is a practical performance upgrade for riders seeking a lightweight, precisely manufactured rear sprocket.
Installation should be performed with the appropriate tools and according to the motorcycle manufacturer’s service procedures. Inspect the chain, front sprocket, and rear sprocket together, and replace worn drivetrain components as needed to support proper engagement and maximize service life.
