The EK 520 MX Chain is a 520 x 120 non-sealed standard roller chain designed for straightforward motocross-style drivetrain use where a traditional, non-sealed chain is preferred. It features gold outer plates with black inner pivot links for a distinctive two-tone look, and it’s built with quad stake riveting to help keep the chain assembled securely under riding loads. This chain includes a clip style master link to make installation and removal easier without special riveting tools, making it a practical choice for regular maintenance and gearing changes.
