Renthal 491-415-40P-OR Rear Sprocket, Aluminum, 40-Tooth, Orange (491--415-40P-OR)

Upgrade your motorcycle’s drivetrain with the Renthal 491-415-40P-OR rear sprocket. CNC-machined rather than stamped, this sprocket uses a computer-aided ultra-light design to reduce unsprung weight and support more efficient power transfer. Its orange finish adds a distinctive look while maintaining the performance-focused construction expected from Renthal components.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. This material is approximately 33% lighter than steel, helping reduce rotating and unsprung mass without sacrificing the strength needed for demanding riding conditions. The lighter design can contribute to improved throttle response, acceleration, and overall drivetrain performance.
A specially engineered tooth profile allows the chain to roll smoothly on and off the sprocket. This design promotes longer sprocket and chain wear, reduces operating noise, and helps transfer power efficiently through the drivetrain. The 40-tooth configuration is designed for compatible GasGas, Husqvarna, and KTM applications; verify fitment against your motorcycle’s model and year before installation.
Built for riders who want durable performance with reduced weight, the Renthal 491-415-40P-OR combines precision CNC machining, advanced aluminum construction, and a chain-friendly tooth profile in a high-quality replacement or upgrade sprocket.
