Renthal Rear Sprocket, 46-Tooth Aluminum, Silver (150U-520-46GBSI)

Upgrade your motorcycle’s final-drive performance with the Renthal 150U-520-46GBSI rear sprocket. CNC-machined rather than stamped, this sprocket uses a computer-aided ultra-light design to help reduce unsprung weight and improve power transfer. Its silver finish provides a clean, performance-focused appearance suited to Honda and Yamaha applications.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum, offering a significant weight advantage over steel while maintaining the strength required for demanding riding. The lightweight construction helps reduce rotating mass, allowing more efficient power delivery and responsive handling without compromising durability.
Renthal’s specialized tooth profile is designed to help the chain roll smoothly onto and off the sprocket. This promotes longer sprocket and chain wear, reduces drivetrain noise, and supports consistent power transfer throughout the service life of the component. The 46-tooth configuration provides a reliable replacement or gearing option for compatible Honda and Yamaha motorcycles.
Designed for riders who demand precision and performance, the Renthal 150U-520-46GBSI combines advanced CNC machining, lightweight 7075-T6 aluminum construction, and a carefully engineered tooth profile. Confirm fitment for your specific motorcycle before installation and follow the manufacturer’s recommended chain and sprocket replacement procedures.
