The EK 520SRX2-160G SRX2 series chain is designed for street sport bikes that require dependable power transfer, reduced friction, and durable performance. Built in the 520 size with 160 links and a gold finish, this chain provides a practical replacement or upgrade option for compatible motorcycle applications. The SRX2 model offers an excellent value for riders seeking responsive drivetrain performance without the added weight of larger chain designs.
Its Quadra X-ring seal design helps reduce friction at the link joints while retaining lubrication more effectively than a conventional O-ring chain. This construction helps extend service life by approximately 1.5 to 2 times compared with standard O-ring designs when properly installed, lubricated, and maintained. Lightening holes in the side plates reduce chain weight by approximately 3 percent, supporting efficient performance for street-oriented sport bike use.
Fitment depends on the motorcycle manufacturer’s specified chain size, link count, sprocket combination, and clearance requirements. Verify that your application calls for a 520 chain and that 160 links are suitable before installation; the chain may require sizing to match the motorcycle and gearing setup. The manufacturer is EK, and the vendor part number is 520SRX2-160G. Use the EK part number when confirming compatibility with your motorcycle, replacement-chain requirements, and installation components.
