Renthal Rear Aluminum Sprocket, 49-Tooth, Silver (154U-520-49GRSI)

Upgrade your motorcycle’s drivetrain with the Renthal 154U-520-49GRSI rear sprocket. CNC-machined rather than stamped, this 49-tooth sprocket features a computer-aided ultra-light design that helps reduce unsprung weight and improve power transfer. Its silver finish provides a clean, durable appearance suited to performance-focused applications.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. This material is 33% lighter than steel, helping reduce rotating and unsprung mass while maintaining the strength required for demanding riding conditions. The lighter construction supports more responsive acceleration and efficient power delivery without sacrificing durability.
Renthal designed the 154U-520-49GRSI with a specialized tooth profile that allows the chain to roll smoothly onto and off the sprocket. This design helps promote longer sprocket and chain wear, reduce drivetrain noise, and improve overall power transfer. It is an ideal replacement or performance upgrade for compatible Honda motorcycle applications using a 520 chain.
