EK 520SRX2 QX-Ring Chain 520 — a transmission chain designed for riders seeking a balance between durability and cost-effectiveness. Part of EK CHAIN's SRX series, this 520SRX2 is intended for 520 pitch transmissions and is suitable for both street and off-road machines: roadsters, motocross, quads, and urban use.
The QX-Ring design minimizes lubricant loss between the links, while the steel/steel construction provides a suitable appearance and durability for demanding uses. Ideal for 520 chains, it integrates with standard transmission systems and is suitable for sport and light trail machines.
Examples of applications (depending on installation and manufacturer specifications): GAS GAS SM 700 (2026), KTM 690 SMC R (2026), YAMAHA YZ 450 F (2026). Please check the number of links and the drive of your sprocket/crown before installation.
