Renthal Rear Sprocket, Aluminum, 48-Tooth, Silver (112U-520-48GESI)

Upgrade your motorcycle’s final-drive performance with the Renthal 112U-520-48GESI rear sprocket. Designed for compatible Kawasaki and Suzuki applications, this silver aluminum sprocket combines lightweight construction with the strength and durability needed for demanding riding conditions. Its CNC-machined design delivers precise, consistent manufacturing, helping reduce unnecessary unsprung weight and support efficient power transfer.
The rear sprocket is produced from high-strength, specially enhanced 7075-T6 aluminum. Compared with a conventional steel sprocket, this construction is approximately 33% lighter, helping reduce rotating mass without sacrificing the strength required for reliable drivetrain operation. The reduced weight can contribute to sharper acceleration response and improved handling feel, making it a practical performance upgrade for street, off-road, and competition-oriented motorcycles.
Renthal also incorporates a specialized tooth profile engineered to help the chain roll smoothly onto and off the sprocket. This design promotes longer sprocket and chain wear, reduces drivetrain noise, and supports more efficient power delivery. The result is a dependable replacement or performance-focused upgrade for riders who want lightweight materials, precise machining, and durable operation from a trusted motorcycle drivetrain brand.
Before installation, verify that the 48-tooth configuration, 520 chain size, and Kawasaki or Suzuki fitment match your motorcycle. Professional installation and proper chain alignment, tension, and lubrication are recommended for optimal performance and service life.
