Upgrade your motorcycle’s drivetrain with the Renthal 518U-420-46GPOR Limited Edition Ultralight Rear Sprocket. Designed for GasGas, Husqvarna, and KTM applications, this orange aluminum rear sprocket combines distinctive styling with race-proven performance. Its limited-edition hard-anodized finish adds a unique appearance while helping protect the sprocket against wear and corrosion in demanding riding conditions.
Renthal UltraLight Rear Sprockets are CNC-machined from high-strength 7075-T6 aluminum to extremely tight tolerances. Compared with conventional steel sprockets, the aluminum construction is approximately 66% lighter, helping reduce unsprung and rotating weight for responsive acceleration and handling. Computer engineering and testing help ensure accurate fitment, concentricity, and load dispersion across the sprocket.
The precision tooth profile is designed to promote efficient power transfer and smooth chain engagement. This Renthal rear sprocket reflects the same performance-focused design used by top Renthal riders, including the limited-edition appearance featured during the Monster Energy Supercross Series. The 46-tooth configuration provides a dependable replacement or performance upgrade for compatible GasGas, Husqvarna, and KTM motorcycles.
Choose the Renthal 518U-420-46GPOR when you want a lightweight, precisely manufactured rear sprocket with a bold orange finish and dependable competition-inspired performance. Confirm motorcycle fitment, chain size, and gearing requirements before installation.
