Renthal Rear Aluminum Sprocket, 47-Tooth, Silver (408U-420-47GESI)

Upgrade your motorcycle’s drivetrain with the Renthal 408U-420-47GESI rear sprocket, engineered for riders who demand efficient power transfer, reduced weight, and dependable durability. Designed for select Kawasaki and Suzuki applications, this 47-tooth sprocket combines advanced CNC machining with a computer-aided ultra-light design to help reduce unsprung weight and improve drivetrain response.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. This material is approximately 33% lighter than steel while maintaining the strength required for demanding riding conditions. Its lightweight construction helps minimize rotating mass, allowing power to transfer more efficiently from the engine to the rear wheel without sacrificing sprocket performance or reliability.
Renthal’s specialized tooth profile is designed to help the chain roll smoothly onto and off the sprocket. This promotes longer chain and sprocket wear, reduces operating noise, and supports consistent power delivery. The silver finish provides a clean, performance-focused appearance suited to a wide range of motorcycle builds.
