EK/PBR 520M3 Chain Kit 13/52 - Standard Sprocket by EK CHAIN
Designed for the motocross world, this 520M3 chain kit combines a gold chain and a standard steel sprocket to meet the demands of off-road riding. Ideal for trial/terrain bikes that require a reliable transmission in the face of mud, debris, and track stresses. The design minimizes friction while providing good resistance to tension and abrasion, useful for both competitive use and intensive training.
Notable compatibility: Honda CR 125 R (JE01) 2000–2001. Easy installation for DIY enthusiasts accustomed to chain/sprocket maintenance: check tension, lubrication, and the condition of the tensioners during installation. This kit provides a polished look thanks to its gold finish while remaining suited to off-road requirements.
