EK/PBR 520MRD7 Chain Kit 13/49 - Ultra-light Sprocket
Specifically designed for off-road and competition use, this EK Chain kit combines a robust 520 chain and a 13/49 sprocket with an ultra-light aluminum rear sprocket. Built for motocross, it offers a balance between abrasion resistance and reduced weight: ideal for those seeking a reliable drive system without adding excess weight to the motorcycle.
The gold finish aids in visually identifying wear, while the aluminum sprocket reduces unsprung mass for sharper acceleration and less inertia at high RPMs. Standard installation and maintenance: check tension, lubricate, and monitor link wear to get the most out of the kit.
