The EK 520 SRX2 drive chain is designed for competition use and OEM replacement applications. Built around the 520-size chain standard, this model provides a practical combination of reduced friction, dependable power transfer, and extended service life for compatible motorcycles and powersports vehicles. The 110-link configuration supports fitment where the original equipment chain uses the same size and link count, subject to the vehicle manufacturer’s specifications.
EK’s Quadra X-Ring design helps retain lubrication and reduce contamination at the chain seals, contributing to an estimated service life of 1.5 to 2 times longer than a standard O-ring chain. Lightening holes help reduce rotating mass while maintaining the performance characteristics expected from a competition-oriented drive chain. The EK 520 SRX2 is suitable for replacing a worn or damaged original chain when the 520 size, 110-link length, and compatible sprocket configuration are confirmed.
This EK chain is supplied with a clip-type master link for installation and service convenience. Always verify the motorcycle model, year, sprocket tooth counts, chain size, and required link count before installation. Proper alignment, lubrication, and adjustment are essential for achieving reliable performance and maximizing chain life. Manufacturer part number 520SRX2-110 and vendor part number 520SRX2-110 identify this specific EK 520 SRX2 configuration.
