The EK 525 Standard Non-Sealed Roller Chain is a durable, economical drive-chain solution designed for compatible motorcycle and powersports applications. This 120-link chain is manufactured by EK Chain and supplied under vendor part number 525-120, providing dependable power transfer for riders and equipment owners who need a practical replacement chain.
Built with special steel alloy components, the EK 525 Standard chain uses solid rollers and pre-stretched, shot-peened parts to support consistent operation and improved resistance to wear. Its standard non-sealed construction is suited for applications that do not require sealed-ring protection, while the two-point pin riveting helps secure the chain assembly during use.
The chain includes a clip-type master link for installation on compatible 525-size chain systems. Always confirm that the 525 pitch and roller-chain configuration match the motorcycle, vehicle, or equipment manufacturer’s specifications before installation. Proper alignment, lubrication, and tension adjustment are recommended to help maximize service life and maintain smooth drivetrain performance.
