EK 520SRX2 QX-Ring Chain 520 - EK CHAIN

The 520SRX2 from EK CHAIN is a robust transmission chain designed for versatile uses: quad, urban, motocross, and roadster. Manufacturer reference: 520SRX2-STL 104 MLJ. Designed for configurations equipped with a 520 pitch, it combines steel construction and QX-Ring seals for durability suited to the demands of both on-road and off-road conditions.

• Type: 520 QX-Ring Chain
• Number of links: 104
• Color: Steel / Steel
• Relative lifespan (100 links): 3300
• Weight (kg / 100 links): 1.54 kg

The presence of QX-Ring seals minimizes lubricant leakage at the links and contributes to controlled wear. Ideal for replacing a worn chain on machines such as the GAS GAS SM 700 (2026), the KTM 690 SMC R (2026), or the YAMAHA YZ 450 F (2026), it adapts well to both demanding drives and urban commutes.

To get the most out of this drive component: regularly check the tension, clean and lubricate according to the manufacturer's recommendations, and inspect the condition of the sprocket and the crown. Proper maintenance preserves the longevity of the chain and the safety of your transmission.
