Renthal Rear Sprocket, Aluminum, 50-Tooth, Silver (216U-520-50GPSI)

Upgrade your motorcycle’s drivetrain with the Renthal 216U-520-50GPSI rear sprocket, engineered for riders who want reduced unsprung weight, efficient power transfer, and dependable durability. This 50-tooth sprocket is CNC-machined rather than stamped, providing precise tooth geometry and consistent performance under demanding riding conditions. Its computer-aided ultra-light design helps reduce rotating mass while maintaining the strength needed for off-road, motocross, and high-performance applications.
The Renthal rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with a comparable steel sprocket, the aluminum construction is approximately 33% lighter, helping reduce unsprung weight and improve power transfer without sacrificing structural integrity. The silver finish delivers a clean, performance-focused appearance that complements a wide range of motorcycle setups.
A specialized tooth profile allows the chain to roll smoothly on and off the sprocket. This design helps promote longer chain and sprocket wear, quieter operation, and efficient power delivery throughout the drivetrain. The result is a rear sprocket built for precise engagement, reduced drivetrain noise, and reliable performance during aggressive riding.
Choose the Renthal 216U-520-50GPSI when you need a lightweight aluminum replacement rear sprocket with race-inspired engineering and dependable durability. Designed for use with a 520 chain, this sprocket combines CNC machining, enhanced 7075-T6 aluminum, and an optimized tooth profile to support responsive handling and consistent performance.
