EK 520SRX2 QX-Ring Transmission Chain — Manufacturer's reference: 520SRX2-STL 76 SLJ
The EK 520SRX2 is designed for riders seeking a reliable transmission chain for a wide range of uses: quad, urban, motocross, or roadster. Presented in a steel/steel finish, it features QX-Ring seals (trade name) and a 520 pitch suitable for common sprockets and crowns found on many modern trails, supermotos, and enduros.
Designed to fit standard transmissions, this chain is suitable for mounting on original or optimized sprockets and crowns. It integrates easily into regular chain maintenance (tension checks, lubrication, and adjustment) for consistent use on-road or off-road.
Examples of compatible models: KTM 690 SMC R (2026), YAMAHA YZ 450 F (2026), HONDA CRF 300 L (2026). Always check the pitch and the number of links required for your motorcycle before installation.
