EK 520SRX2 QX-Ring Chain 520 ā a robust and versatile drive chain from EK CHAIN, displayed in a gold finish. Designed to replace the original transmission on road, cross, urban, and quad machines, it offers a balance between durability and cost, making it a frequent choice among discerning riders.
Equipped with QX-Ring seals between the links and rollers, this chain minimizes direct exchange between lubricant and the environment while remaining suitable for various sprocket and crown configurations. Its profile is suitable for urban rides as well as off-road sessions or use on sport roadsters.

Before installation, check the number of links and the pitch to ensure perfect compatibility with your sprocket and crown. The gold finish adds a polished visual touch to the transmission and facilitates identification during maintenance.
