EK/JT 520MRD7 13/48 Chain Kit - Ultra-Light Sprocket

Designed for motocross and the demands of intense rides, this EK/JT chain kit combines a gold-colored 520MRD7 chain with an ultra-light aluminum sprocket. The set aims for a balance between lightness and robustness, suitable for off-road motorcycles where every gram counts on the scale without compromising wear resistance.
