Renthal Rear Sprocket, Aluminum, 47-Tooth, Silver for Honda (154U-520-47GRSI)

Upgrade your Honda motorcycle with the Renthal 154U-520-47GRSI rear sprocket, engineered for dependable performance, reduced weight, and efficient power transfer. This 47-tooth sprocket is CNC-machined rather than stamped, allowing Renthal to produce a precise, computer-aided ultra-light design that helps reduce unsprung weight and improve drivetrain response. Its silver finish adds a clean, performance-oriented appearance while maintaining the durability expected from a high-quality replacement sprocket.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with steel, this material is 33% lighter, helping reduce rotating mass without sacrificing the strength needed for demanding street or off-road riding. The result is a lightweight drivetrain component designed to support responsive acceleration, controlled handling, and consistent power delivery. As a genuine Renthal component, part number 154U-520-47GRSI is built to meet the fitment and performance requirements of compatible Honda applications.
A specially engineered tooth profile allows the chain to roll smoothly on and off the sprocket. This design promotes longer chain and sprocket wear, reduces operating noise, and helps transfer engine power efficiently through the final drive. The precise CNC-machined construction and durable aluminum alloy make this sprocket a practical choice for riders seeking a performance-focused replacement that balances low weight, strength, and long-term reliability.
