Renthal Rear Sprocket, Aluminum, 50-Tooth, Orange (441U-428-50GPOR)

Upgrade your motorcycle’s drivetrain with the RENThAL 441U-428-50GPOR rear sprocket, engineered for riders who want reduced unsprung weight, efficient power transfer, and dependable performance. Designed for compatible GasGas, Husqvarna, and KTM applications, this orange aluminum sprocket combines CNC-machined precision with a lightweight construction that supports responsive handling and acceleration.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with steel, this material is 33% lighter, helping reduce rotating and unsprung weight while maintaining the strength needed for demanding riding conditions. The computer-aided ultra-light design further improves power transfer without sacrificing durability, making it a practical choice for motocross, off-road, and performance-focused applications.
RENTHAL also incorporates a special tooth profile that helps the chain roll smoothly on and off the sprocket. This design promotes longer chain and sprocket wear, reduces drivetrain noise, and supports efficient power delivery. CNC machining provides accurate tooth formation and consistent fitment, while the orange finish adds a distinctive appearance to your motorcycle’s drivetrain.
Choose the RENThAL 441U-428-50GPOR when you need a lightweight, precisely manufactured rear sprocket built for reliable performance. Verify your motorcycle’s year, model, chain size, and original equipment specifications before installation to ensure proper compatibility.
