Renthal Rear Aluminum Sprocket, 46-Tooth, Silver (154U-520-46GRSI)

The REN­THAL 154U-520-46GRSI rear sprocket is CNC-machined from high-strength 7075-T6 aluminum for a precise, lightweight replacement designed to improve motorcycle drivetrain performance. Its computer-aided ultra-light design helps reduce unsprung weight, supporting quicker suspension response and more efficient power transfer. Finished in silver, this 46-tooth sprocket provides a durable, performance-focused solution for compatible Honda applications.
The 7075-T6 aluminum construction is specially enhanced to deliver an excellent balance of low weight and strength. Compared with a steel sprocket, the aluminum design is approximately 33% lighter, helping reduce rotating mass without sacrificing the durability needed for demanding street, trail, and competition use. CNC machining also provides consistent tooth geometry and accurate fitment compared with stamped alternatives.
RENTHAL incorporates a special tooth profile that allows the chain to roll smoothly on and off the sprocket. This design helps promote longer chain and sprocket wear, reduce operating noise, and support efficient power delivery throughout the drivetrain. The 154U-520-46GRSI is an ideal choice for riders seeking a high-quality rear sprocket that combines lightweight construction, dependable strength, and refined chain engagement. Verify application and gearing compatibility before installation.
