The EK/JT 520H 14/47 - ultra-light sprocket kit is designed for motocross riders looking for a ready-to-install set, crafted according to EK JAPAN standards. This kit combines a robust 520H chain with an ultra-light aluminum sprocket to minimize unsprung weight without compromising compatibility with 520 type transmissions.
Easy to install on a 520 type transmission, this kit is particularly suitable for motocross machines where every gram counts. The aluminum sprocket reduces inertia while maintaining expected wear in line with the manufacturer's specifications. Ideal for regular maintenance or reconditioning after a season, it allows for a chain and gearing suited to the terrain.
