The EK 520SRX2-150G SRX2 Quadra X-Ring chain is designed for street motorcycles and sport bikes that require dependable power transfer, reduced friction, and long service life. This 520-size chain features 150 links and a gold finish, making it a practical replacement or upgrade for compatible motorcycle drivetrains. The SRX2 series delivers excellent value for everyday street machines while supporting smooth, consistent operation.
Its Quadra X-ring design helps reduce friction at the link interfaces and extends chain life by approximately 1.5 to 2 times compared with a standard O-ring chain. This sealing design helps retain lubricant and limit the intrusion of dirt and moisture, supporting reliable performance during regular road use. Lightening holes in the side plates reduce chain weight by approximately 3 percent without compromising the chain’s intended street-bike application.
Verify fitment against your motorcycle manufacturer’s specifications, including chain size, required link count, sprocket compatibility, and drivetrain configuration. The EK 520SRX2-150G is supplied as a 520-size, 150-link SRX2 Quadra X-ring chain and may require sizing or an appropriate connecting link during installation, depending on the application.
