The EK 520SRX2 drive chain is designed for competition use and OEM replacement applications. This 104-link chain features a 520-size configuration and EK’s Quadra X-Ring design, helping reduce friction while improving sealing and chain durability. It is a suitable replacement for compatible motorcycles, powersports vehicles, and other applications requiring a 520 chain with matching fitment specifications.
Fitment: Intended for vehicles that require an EK 520SRX2 chain in a 104-link configuration. Confirm the original equipment chain size, link count, sprocket compatibility, and manufacturer fitment requirements before installation. The chain is supplied with a clip-type master link for convenient installation when compatible with the application.
The EK 520SRX2 is engineered with lightening holes to help reduce rotating mass while maintaining dependable performance. Its reduced-friction construction supports smooth power transfer, and the Quadra X-Ring configuration is designed to extend service life approximately 1.5 to 2 times longer than a standard O-ring chain under comparable conditions. Always follow the vehicle manufacturer’s chain installation, tension, lubrication, and maintenance recommendations.
