Renthal Rear Sprocket, Aluminum, 50-Tooth, Green (408U-420-50GEGN)

The Renthal 408U-420-50GEGN rear sprocket is CNC-machined rather than stamped for precise construction and dependable performance. Designed for Kawasaki and Suzuki motorcycles, this 50-tooth aluminum sprocket helps reduce unsprung weight while improving power transfer for responsive acceleration and handling. Its green finish adds a distinctive appearance while maintaining the performance-focused design expected from Renthal drivetrain components.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. This material is approximately 33% lighter than steel, helping reduce rotating mass without sacrificing the strength needed for demanding riding conditions. The reduced weight can contribute to improved suspension response, smoother handling, and more efficient transfer of engine power to the rear wheel.
Renthal’s computer-aided ultra-light design removes unnecessary material while preserving structural integrity. A specially engineered tooth profile allows the chain to roll smoothly onto and off the sprocket, helping reduce friction, operating noise, and chain wear. This design supports longer component life and consistent drivetrain performance when properly installed and maintained.
Use the Renthal 408U-420-50GEGN as a reliable replacement or performance upgrade for compatible Kawasaki and Suzuki applications. Verify motorcycle fitment, chain size, and final-drive specifications before installation. For best results, inspect the chain and front sprocket at the same time and replace worn drivetrain components as needed.
