The EK 520SRX2 drive chain is designed for competition use and OEM replacement applications. Built for 520-size motorcycle drivetrains, this 150-link chain provides a dependable replacement solution for riders who need consistent power transfer and durable performance. The chain is supplied by EK and identified by manufacturer and vendor part number 520SRX2-150.
Its Quadra X-Ring design helps reduce friction while improving sealing around the chain pins and bushings. Compared with a standard O-ring chain, this design can provide approximately 1.5 to 2 times longer chain life when properly installed, lubricated, and maintained. Lightening holes help reduce rotating weight without compromising the chain’s intended use in competition and OEM replacement applications.
Fitment: Fits motorcycles and powersports vehicles specified for a 520-size drive chain with a 150-link configuration. Verify the vehicle manufacturer’s chain size, link count, sprocket compatibility, and required master-link style before installation. A clip-type master link is included for installation and service.
