The EK 520 Standard Non-Sealed Roller Chain is a dependable replacement chain for compatible motorcycles, ATVs, and other powersports applications requiring a 520-size chain with 110 links. Manufactured by EK and identified by manufacturer and vendor part number 520-110, this chain is designed for reliable power transfer and practical service performance in demanding riding environments.
Built from special steel alloy, the EK 520 Standard chain features solid rollers and pre-stretched components to help support consistent operation and reduce initial adjustment requirements. Shot-peened parts improve surface durability, while two-point pin riveting helps provide secure, dependable assembly. The non-sealed design is a practical choice for applications where a conventional roller chain is specified and routine lubrication and maintenance are part of the service schedule.
This 110-link chain includes a clip-type master link for installation on compatible 520 chain systems. Confirm the motorcycle, ATV, or equipment manufacturer’s fitment requirements before installation, including chain size, link count, sprocket compatibility, and master-link specifications. Proper alignment, lubrication, tension, and inspection are essential for maximizing chain life and maintaining safe drivetrain operation. The product is supplied as an EK 520 Standard non-sealed chain and is not intended to replace sealed-chain applications unless specifically approved by the equipment manufacturer.
