Renthal Rear Sprocket, 51-Tooth Aluminum, Silver (112U-520-51GESI)

Upgrade your motorcycle’s drivetrain with the Renthal 112U-520-51GESI rear sprocket, engineered for riders who demand efficient power transfer, reduced unsprung weight, and dependable performance. Designed for compatible Kawasaki and Suzuki applications, this 51-tooth sprocket combines precision CNC machining with a lightweight aluminum construction for a performance-focused replacement or upgrade.
The rear sprocket is CNC-machined rather than stamped, allowing Renthal to produce an accurate, computer-aided ultra-light design that helps reduce unsprung weight. Its high-strength 7075-T6 aluminum construction is specially enhanced for durability and is approximately 33% lighter than comparable steel sprockets. The result is a lighter drivetrain component that supports responsive handling and efficient power transfer without sacrificing strength.
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, reduced operating noise, and consistent power delivery throughout the drivetrain. The silver finish provides a clean, performance-oriented appearance while complementing a wide range of motorcycle setups.
Install the Renthal 112U-520-51GESI rear sprocket as part of a properly matched chain and drivetrain system. Verify tooth count, chain size, mounting pattern, and motorcycle compatibility before installation. Professional installation and correct chain alignment are recommended for safe, reliable operation.
