The EK 520 SRX2 drive chain is designed for competition use and OEM replacement applications where reliable power transfer and extended service life are important. This 520-size chain includes 116 links and is manufactured by EK for compatible motorcycle and powersports drivetrain systems using a 520 chain specification. Verify the original equipment application, sprocket compatibility, and required link count before installation.
Featuring lightening holes and a reduced-friction design, the EK 520 SRX2 helps support efficient drivetrain performance while minimizing unnecessary rotating weight. Its Quadra X-Ring sealing design helps retain lubrication and limit contaminant intrusion at the link joints, providing a chain life estimated at 1.5 to 2 times longer than a standard O-ring chain under comparable conditions. Performance will vary based on application, maintenance, riding conditions, and installation.
The EK 520 SRX2-116 includes a clip-type master link for installation and service convenience. The master link should be installed according to EK instructions, with proper alignment and secure clip positioning. Regular cleaning, lubrication, tension checks, and inspection are recommended to help maintain smooth operation and maximize chain life. This EK chain is identified by manufacturer and vendor part number 520SRX2-116.
