Renthal Rear Sprocket, 49-Tooth Aluminum, Black (150U-520-49GBBK)

Upgrade your motorcycle’s drivetrain with the Renthal 150U-520-49GBBK rear sprocket. CNC-machined rather than stamped, this high-performance sprocket uses a computer-aided ultra-light design to help reduce unsprung weight and improve power transfer. Its black finish provides a clean, durable appearance suitable for performance-focused street and off-road applications.
The Renthal rear sprocket is manufactured from specially enhanced 7075-T6 aluminum, delivering a strong and lightweight alternative to conventional steel sprockets. The aluminum construction is approximately 33% lighter than steel, helping reduce rotating mass without sacrificing the strength required for demanding riding conditions. Lower weight at the rear wheel can contribute to more responsive acceleration, handling, and suspension performance.
A specially engineered tooth profile allows the chain to roll smoothly on and off the sprocket. This design helps promote longer chain and sprocket wear, reduced drivetrain noise, and efficient power transfer. The 49-tooth configuration is designed for compatible Honda and Yamaha applications, making the Renthal 150U-520-49GBBK a reliable choice for riders seeking precise fitment and performance-oriented durability.
