Renthal Rear Aluminum Sprocket, 48-Tooth, Silver (224U-520-48GPSI)

The Renthal 224U-520-48GPSI rear sprocket is engineered for riders who demand efficient power transfer, reduced weight, and dependable drivetrain performance. CNC-machined rather than stamped, this 48-tooth sprocket features a computer-aided ultra-light design that helps reduce unsprung weight and allows the suspension and drivetrain to perform more efficiently. Its silver finish provides a clean, professional appearance suitable for a wide range of motorcycle applications.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with conventional steel sprockets, this material is approximately 33% lighter, helping reduce rotational and unsprung mass without sacrificing the strength needed for demanding riding conditions. The lightweight construction supports quicker response and improved power transfer while maintaining the durability expected from Renthal components.
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 drivetrain noise, and deliver more consistent power transmission. The precision-machined construction and carefully developed tooth geometry make the Renthal 224U-520-48GPSI a reliable replacement or performance upgrade for compatible motorcycle drivetrains.
Install this Renthal rear sprocket according to the motorcycle manufacturer’s service procedures and verify chain, fitment, and alignment before use. Its combination of CNC machining, enhanced aluminum construction, and optimized tooth design makes it a practical choice for riders seeking lower weight and reliable drivetrain performance.
