Renthal Rear Sprocket, 51-Tooth 7075-T6 Aluminum, Silver (150U-520-51GBSI)

Upgrade your motorcycle’s final-drive performance with the Renthal 150U-520-51GBSI rear sprocket. Designed for compatible Honda and Yamaha applications, this 51-tooth sprocket is CNC-machined rather than stamped for precise construction and a consistent fit. Its computer-aided ultra-light design helps reduce unsprung weight, supporting quicker response and more efficient power transfer.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with steel, this material is 33% lighter, helping reduce drivetrain weight without sacrificing the strength needed for demanding riding. The silver finish provides a clean, performance-oriented appearance while complementing a wide range of motorcycle setups.
Renthal’s specialized 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 more efficiently through the final drive. The 150U-520-51GBSI is a practical choice for riders seeking a lightweight, durable replacement or performance-focused sprocket for compatible Honda and Yamaha motorcycles.
