Upgrade your motorcycle’s final-drive performance with the SUPERSPROX Stealth Rear Sprocket, part number RST-990-50-GLD. Designed for select Husaberg, Husqvarna, and KTM applications, this 50-tooth rear sprocket combines a lightweight aluminum core with durable steel teeth to help extend drivetrain service life without adding unnecessary weight. Its gold finish provides a clean, race-inspired appearance while supporting dependable performance in demanding riding conditions.
The SUPERSPROX Stealth design uses steel teeth engineered to last up to four times longer than comparable aluminum teeth, helping reduce wear and maintain consistent chain engagement over time. The aluminum core is 70% lighter than steel, creating a strong pound-for-pound sprocket that supports responsive handling and efficient power transfer. This combination makes the RST-990-50-GLD a practical choice for riders seeking durability and weight savings in one rear sprocket.
Forged rivets secure the sprocket construction and provide exceptional strength under repeated acceleration, shifting, and off-road use. The result is a robust drivetrain component built to withstand demanding riding while helping preserve the benefits of a lighter rotating assembly. Verify vehicle fitment and chain compatibility before installation to ensure the correct application for your motorcycle.
