The EK 428SR-120 is a heavy-duty, non-sealed roller chain designed for dependable performance in motorcycle and powersports applications. This 428 SR chain includes 120 links and is engineered for riders and technicians who need a durable replacement chain for compatible drive systems. The EK brand is recognized for producing motorcycle chains with practical construction and consistent manufacturing quality.
Built with special steel alloy components, the EK 428SR-120 features solid rollers, solid bushings, and pre-stretched, shot-peened parts to help support long wear life and reliable operation. Four-point riveting reinforces the chain assembly, while the included clip-type master link simplifies installation and service. As a non-sealed design, this chain is intended for applications that specify a standard 428-size roller chain rather than an O-ring or X-ring chain.
Verify your motorcycle or powersports vehicle’s chain specification, sprocket compatibility, and required link count before installation. The EK manufacturer part number and vendor part number are both 428SR-120. Proper alignment, lubrication, tension, and regular inspection are recommended to help maintain chain performance and protect related drivetrain components.
