Renthal Rear Sprocket, Aluminum, 51-Tooth, Black for Honda and Yamaha (150U-520-51GBBK)

Upgrade your motorcycle’s drivetrain with the Renthal 150U-520-51GBBK rear sprocket. CNC-machined rather than stamped, this aluminum sprocket uses a computer-aided ultra-light design to help reduce unsprung weight and improve power transfer. Its black finish provides a clean, durable appearance suited to performance-focused Honda and Yamaha applications.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with steel, this material is approximately 33% lighter, helping reduce rotating and unsprung mass without sacrificing the strength required for demanding riding conditions. The reduced weight can contribute to more responsive acceleration, handling, and overall drivetrain performance.
Renthal’s special tooth profile is designed to help the chain roll smoothly onto and off the sprocket. This promotes longer wear, reduced operating noise, and efficient power transfer throughout the drivetrain. The 51-tooth configuration is engineered for compatible Honda and Yamaha motorcycles requiring this application-specific fitment.
Install the Renthal 150U-520-51GBBK rear sprocket as part of a properly matched chain and front sprocket system. Confirm vehicle fitment and drivetrain specifications before installation to ensure compatibility and reliable performance.
