Renthal Rear Sprocket, Aluminum, 42-Tooth, Orange (224U-520-42GPOR)

Upgrade your motorcycle’s final-drive performance with the Renthal 224U-520-42GPOR rear sprocket. CNC-machined rather than stamped, this aluminum sprocket uses a computer-aided ultra-light design to reduce unsprung weight and support more efficient power transfer. Its orange finish adds a distinctive appearance while maintaining the precise fit and reliable function expected from Renthal drivetrain components.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum, providing a lightweight alternative to steel without sacrificing strength. The material is designed to reduce rotating and unsprung mass, helping improve acceleration response and handling feel. This construction makes the Renthal 224U-520-42GPOR a practical choice for riders seeking dependable performance in demanding street, off-road, motocross, or competition applications.
A specially engineered tooth profile allows the chain to roll smoothly on and off the sprocket. This design helps promote longer chain and sprocket wear, reduce operating noise, and maintain efficient power transfer throughout the drivetrain. The 42-tooth configuration is intended for applications requiring a compatible 520 chain and appropriate final-drive gearing. Confirm motorcycle fitment and gearing requirements before installation.
