Renthal Rear Sprocket, Aluminum, 48-Tooth, Black for Honda and Yamaha (150U-520-48GBBK)

Upgrade your motorcycle’s drivetrain with the Renthal 150U-520-48GBBK rear sprocket. Designed for compatible Honda and Yamaha applications, this 48-tooth sprocket is CNC-machined from high-strength 7075-T6 aluminum for a precise, lightweight construction. Its computer-aided design helps reduce unsprung weight, supporting improved power transfer and responsive handling without compromising durability.
Renthal enhances the sprocket with a specially developed tooth profile that allows the chain to roll smoothly on and off the teeth. This design helps promote longer chain and sprocket wear, reduces drivetrain noise, and supports efficient power delivery during acceleration. The aluminum construction is approximately 33% lighter than steel, helping reduce rotational mass while maintaining the strength needed for demanding riding conditions.
Finished in black, the Renthal 150U-520-48GBBK combines functional performance with a clean, race-inspired appearance. CNC machining provides consistent tooth geometry and reliable fitment, while the 48-tooth configuration is suited for riders seeking compatible gearing for their Honda or Yamaha motorcycle. Verify your motorcycle’s application and required chain size before installation.
