Designed for demanding riders, this sprocket is particularly suited for small displacement motocross bikes (85 cc) and fits common models such as KTM 85 SX, Husqvarna TC 85, and Gas Gas MC 85 (check compatibility based on year and wheel configuration). Its construction combines lightness and robustness to maintain transmission precision without overloading the rear wheel.
