Renthal Rear Sprocket, Aluminum, 51-Tooth, Silver (224U-520-51GPSI)

Upgrade your motorcycle’s drivetrain with the Renthal 224U-520-51GPSI rear sprocket, engineered for riders who demand efficient power transfer, reduced unsprung weight, and dependable durability. This CNC-machined sprocket is produced from high-strength 7075-T6 aluminum and finished in silver for a clean, performance-focused appearance. Its ultra-light computer-aided design helps reduce rotating mass compared with conventional steel sprockets, supporting sharper acceleration and responsive handling.
The Renthal 224U-520-51GPSI uses a specially enhanced aluminum alloy that is approximately 33% lighter than steel while maintaining the strength needed for demanding riding conditions. Reduced sprocket weight can help improve suspension response and drivetrain efficiency, making this rear sprocket a practical choice for performance-oriented street, off-road, and racing applications when matched to the correct chain and front sprocket.
A precision-engineered tooth profile allows the chain to roll smoothly onto and off the sprocket. This design promotes longer wear, quieter operation, and consistent power delivery throughout the service life of the drivetrain. CNC machining also provides accurate tooth geometry and a uniform finished surface, helping the sprocket perform reliably under repeated acceleration and shifting.
Designed for compatibility with a 520 chain size and configured with 51 teeth, the Renthal 224U-520-51GPSI delivers a balanced combination of response and gearing range for suitable applications. Verify your motorcycle’s fitment, chain size, tooth count, mounting pattern, and clearance before installation. Use proper installation procedures and inspect the entire drivetrain to support safe, dependable performance.
