The EK 420SH Motorcross Series Chain is designed for motocross motorcycles and other compatible powersport applications requiring a dependable 420-size drive chain. This chain includes 120 links and a gold finish, making it a practical replacement for compatible chain-and-sprocket systems. Manufactured by EK and supplied under vendor part number 420SH-120G, it is built for riders who need consistent performance in demanding riding conditions.
EK uses CRH pin treatment to create an extremely hard outer coating with a softer inner structure. This treatment helps increase chain strength while reducing wear during operation. The result is a durable chain designed to support reliable power transfer, proper fitment, and extended service life when installed and maintained according to the motorcycle manufacturer’s requirements.
The EK 420SH includes a clip-type connecting link for installation. Verify that your motorcycle uses a 420-size chain, accepts a 120-link configuration, and is compatible with the EK 420SH Motorcross Series before installation. Proper chain tension, lubrication, alignment, and regular inspection are recommended for safe operation and optimal service life.
