EK/PBR 520M3 Chain Kit 13/50 - Standard Sprocket
Designed for off-road and enduro/cross competition, this EK CHAIN kit combines a 520M3 chain with a sprocket/crown set in a 13/50 configuration. Ideal for hard off-road sessions, it aims to reduce friction while providing durability against the traction and abrasion encountered on muddy or rocky tracks.
Designed for riders who push their machine to the limit, this kit facilitates regular maintenance (tension, lubrication, link inspection) and fits many small displacement cross bikes. Compatible with models like the HUSQVARNA WR 125 (2001–2013) listed, it is suitable for riders looking for a durable chain and a well-designed transmission. Manufacturer reference: not provided.
