Renthal Rear Sprocket, Aluminum, 45-Tooth, Silver for Honda (154U-520-45GRSI)

The RENTHAL 154U-520-45GRSI rear sprocket is engineered for Honda motorcycles and built to deliver efficient, dependable power transfer. CNC-machined rather than stamped, this aluminum sprocket uses a computer-aided ultra-light design to reduce unsprung weight and help improve acceleration, handling, and drivetrain response. Its silver finish adds a clean, performance-focused appearance while maintaining the durability expected from RENTHAL components.
Constructed from high-strength, specially enhanced 7075-T6 aluminum, the 45-tooth rear sprocket is approximately 33% lighter than a comparable steel sprocket. This weight reduction helps minimize rotating and unsprung mass without sacrificing the strength required for demanding riding conditions. The result is a responsive drivetrain component suitable for riders seeking improved performance without unnecessary weight.
The RENTHAL 154U-520-45GRSI also features a specialized tooth profile designed to help the chain roll smoothly on and off the sprocket. This design promotes longer sprocket and chain wear, reduces operating noise, and supports efficient power delivery throughout the drivetrain. Engineered for reliable fitment and consistent performance, this Honda-compatible rear sprocket is a practical upgrade for maintaining or enhancing your motorcycle’s final drive system.
