The EK 520-480 Sport Non-Sealed Chain is designed for lower-horsepower dirt bike, ATV, and street applications. Supplied in a 25-foot roll, this chain provides a practical solution for custom-length installations, replacement work, and performance-focused powersports maintenance. Its non-sealed construction is well suited to applications where straightforward serviceability and economical operation are priorities.
Each chain is pre-stretched and shot-peened to support consistent performance and improved durability during use. Solid rollers and heat-treated steel construction provide a dependable step up from a standard OEM replacement chain, helping the EK 520-480 deliver reliable power transfer for compatible 520 chain-drive systems. The chain can be cut to the required length and should be properly sized, riveted, lubricated, and tensioned according to the vehicle and application requirements.
Fitment is intended for compatible lower-horsepower dirt bikes, ATVs, and street motorcycles using a 520-size drive chain. Always verify the vehicle manufacturer’s chain size, required link count, sprocket compatibility, and service specifications before installation. This product is manufactured by EK and is identified by manufacturer part number 520-480 and vendor part number 69-3825.
