The Dirt Tricks KTM-47-RAW Rear Sprocket is a 47-tooth chromoly sprocket designed for off-road motorcycles using a 520 chain. Developed by Dirt Tricks president and engineer Greg Burns, this sprocket reflects extensive experience with aerospace steels, advanced heat treatments, and finite element analysis. Its minimalist design delivers the durability needed for demanding riding while maintaining a weight comparable to aluminum sprockets.
Built for riders who require dependable drivetrain performance, the Dirt Tricks KTM-47-RAW uses high-strength chromoly steel that is 2.5 times stronger than stainless steel. The raw finish provides a functional, competition-ready appearance, while the engineered tooth profile helps support long service life under hard riding conditions. This rear sprocket is suited for compatible KTM, GasGas, Husqvarna, and Sherco applications using a 520 chain and the correct 47-tooth gearing configuration. Confirm motorcycle fitment and hub compatibility before installation.
Dirt Tricks backs its rear sprockets with a two-year guarantee. If the sprocket wears out within the coverage period, the manufacturer will replace it according to the terms of the guarantee. The combination of chromoly construction, carefully engineered geometry, and proven off-road durability makes the KTM-47-RAW a strong replacement or gearing-upgrade choice for trail, enduro, motocross, and other serious riding applications.
