The EK 420-110 Chain Sport Non-Sealed chain is designed for lower-horsepower dirt bikes, ATVs, and street applications. This 420 series chain features a 110-link configuration and provides a practical replacement option for compatible original equipment chains. Its non-sealed design is well suited for applications where straightforward maintenance, efficient power transfer, and economical operation are priorities.
Manufactured by EK and supplied under vendor part number 420-110, this chain uses pre-stretched construction and shot-peened components to help improve durability and reduce initial adjustment requirements. Solid rollers and heat-treated steel provide a dependable step up from a basic OEM replacement, supporting consistent performance in recreational and everyday riding conditions. Proper lubrication and adjustment should be maintained according to the motorcycle or ATV manufacturer’s service recommendations.
Fitment includes the 2013–2015 Honda CRF110F, 1979–1984 Honda XR80, and 2004 Honda CRF50F. Verify the original chain size, link count, sprocket compatibility, and vehicle application before installation. This EK chain is intended for compatible 420-drive systems and should be installed using appropriate tools and procedures.
