Renthal Rear Aluminum Sprocket, 49-Tooth Red (154U-520-49GRRD)

The Renthal 154U-520-49GRRD rear sprocket is CNC-machined from high-strength 7075-T6 aluminum for dependable performance and reduced unsprung weight. Unlike stamped sprockets, its computer-aided ultra-light design helps improve power transfer while maintaining the strength required for demanding riding conditions. The 49-tooth configuration and red finish provide a performance-focused replacement for compatible Honda applications.
The specially enhanced aluminum construction is approximately 33% lighter than steel, helping reduce rotating and unsprung mass without sacrificing durability. This lighter design allows the drivetrain to transfer power more efficiently, supporting responsive acceleration and precise performance on the track or trail.
Renthal also incorporates a specialized tooth profile that helps the chain roll smoothly onto and off the sprocket. This design promotes longer chain and sprocket wear, reduces drivetrain noise, and contributes to more efficient power delivery. The result is a high-quality rear sprocket engineered for riders who want lightweight performance, reliable strength, and consistent operation.
Designed for compatible Honda motorcycles, the Renthal 154U-520-49GRRD offers a direct, performance-oriented solution for replacing a worn rear sprocket or upgrading the final-drive system. Verify motorcycle fitment and gearing requirements before installation.
