The EK CHAIN 520MRD7 13/49 chain kit - ultra-light sprocket is designed for motocross riders who want a lightweight and refined transmission. With a gold-coated chain paired with an ultra-light aluminum sprocket, this kit combines appearance and weight optimization without unverified technical promises. Designed for off-road demands, it facilitates throttle response and gear changes on muddy or sandy tracks.

This kit is particularly suited for motocross machines such as the SUZUKI RM-Z 250 (models 2010–2012) and other similar enduro/motocross bikes equipped with a 520 pitch. The aluminum sprocket reduces rotational mass for a more responsive performance, while the treated chain offers a finish that withstands the rigors of the terrain.
