The EK 525 SRX2 drive chain is designed for competition use and OEM replacement applications. This 110-link chain is built for riders and technicians who need dependable power transfer, reduced friction, and extended service life in demanding motorcycle applications. The chain’s 525 size supports compatibility with motorcycles specified for a 525 drive-chain system, while the EK brand provides a trusted replacement option for performance-focused maintenance.
Featuring lightening holes and EK’s Quadra X-Ring design, the 525SRX2-110 helps reduce friction between the chain’s moving components while retaining lubrication more effectively than a standard O-ring chain. These design elements contribute to smoother operation and can help extend chain life by approximately 1.5 to 2 times compared with a conventional O-ring chain, depending on riding conditions, maintenance, and drivetrain setup.
Fitment: Intended for motorcycles requiring a 525-size drive chain with 110 links. Confirm the motorcycle manufacturer’s specifications, sprocket configuration, chain length, and required master-link style before installation. The included screw-type master link supports installation without specialized riveting equipment, but it should be installed and tightened according to EK’s instructions and the motorcycle manufacturer’s service recommendations.
The EK 525 SRX2 drive chain, manufacturer part number 525SRX2-110 and vendor part number 525SRX2-110, is suitable for competition and OEM replacement use where durable construction, reduced friction, and extended chain performance are priorities. Proper alignment, lubrication, tension adjustment, and routine inspection are essential for maximizing service life and maintaining safe operation.
