Renthal Rear Sprocket, 50-Tooth Aluminum, Purple (123U-520-50GYPE)

Upgrade your motorcycle’s drivetrain with the Renthal 123U-520-50GYPE rear sprocket, engineered for strong, efficient power transfer and reduced unsprung weight. This 50-tooth sprocket is CNC-machined rather than stamped, delivering precise tooth geometry and consistent performance for riders who demand dependable drivetrain components. Its purple finish adds a distinctive appearance while maintaining the functional performance expected from Renthal products.
Constructed from high-strength, specially enhanced 7075-T6 aluminum, the sprocket is designed to be significantly lighter than a comparable steel sprocket without sacrificing strength. The reduced weight helps decrease unsprung mass, which can support more responsive suspension performance and improved acceleration. Its computer-aided ultra-light design balances weight savings with the durability needed for demanding street, off-road, and competition applications.
The Renthal 123U-520-50GYPE also features a specialized tooth profile that helps the chain roll smoothly onto and off the sprocket. This design promotes longer chain and sprocket wear, reduced drivetrain noise, and efficient power delivery. Built for compatibility with 520 chain systems and specified for select Suzuki applications, this rear sprocket provides a practical performance upgrade for riders seeking lightweight construction, precise machining, and reliable long-term service.
