The EK 428 Standard Non-Sealed Roller Chain is an economical replacement chain designed for compatible motorcycle and powersports applications. This 120-link chain provides dependable power transfer for systems requiring a standard 428 chain size and non-sealed construction. The chain is supplied with a clip-type master link for installation and service convenience.
Manufactured by EK, the 428-120 features special steel alloy components, solid rollers, and pre-stretched construction to support consistent operation. Shot-peened parts improve surface durability and help the chain withstand the repeated loads associated with drivetrain use. The two-point pin riveting provides secure assembly and contributes to reliable chain performance when properly installed and maintained.
Fitment depends on the application’s required chain size, length, sprocket configuration, and manufacturer specifications. Verify that your motorcycle, powersports vehicle, or compatible mechanical drive system calls for a standard non-sealed 428 chain with 120 links before ordering. The included clip-type master link should be installed according to the vehicle or equipment manufacturer’s service instructions, with correct alignment, lubrication, and adjustment completed during installation.
