The EK 520-84 Sport Non-Sealed Drive Chain is designed for lower-horsepower dirt bikes, ATVs, and street applications. Manufactured by EK and supplied under vendor part number 520-84, this 520-size chain provides a practical replacement option for worn or damaged original-equipment chains. Its 84-link configuration is suitable for applications requiring this specific chain length, subject to final gearing and vehicle setup verification.
Built with solid rollers and heat-treated steel components, the EK 520-84 offers dependable performance for recreational and utility riding. The chain is pre-stretched and shot-peened to help improve strength, reduce initial elongation, and support consistent service life. As a non-sealed design, it is best suited for riders who follow regular cleaning, lubrication, and adjustment procedures.
Fitment includes select Honda and Polaris applications, including the 1984–1986 Honda ATC200S, 1981–1982 Honda ATC250R, and 1994–1999 Polaris Sport 400L. Confirm the required chain size, link count, gearing, and manufacturer application before installation. Proper alignment, tension, lubrication, and maintenance are recommended to help maximize chain life and drivetrain performance.
