EK CHAIN 520SRX2 QX-Ring 520 — manufacturer reference: 520SRX2-STL 108 SLJ
The EK 520SRX2 QX-Ring drive chain is designed for riders looking for a good balance between reliability and cost. Coming from the renowned SRX series known for its performance/value ratio, this chain is suitable for urban, road, cross, or quad use. The QX-Ring o-ring reduces friction losses and helps retain lubricant between the links, without promising performance beyond manufacturer specifications.
Designed for final drive, it installs on standard 520 sprockets and crowns. Before installation, check the condition of the sprocket and crown and adjust the tension according to the manufacturer's recommendations. Proper lubrication and regular checks will extend the effective performance of the drive.
Common compatibilities: KTM 690 SMC R (2026), YAMAHA YZ 450 F (2026), HONDA CRF 300 L (2026). Suitable for both road and off-road configurations, the 520SRX2 remains a versatile choice for those seeking a robust and easy-to-maintain chain.
