EK 520SRX2 QX-Ring Drive Chain — manufacturer reference: 520SRX2-STL 126 SKJ. Coming from EK CHAIN's SRX series, this standard pitch 520 chain is designed to equip a wide range of machines, from trail to sport bikes. Its QX-Ring configuration ensures the sealing of the links to limit lubricant loss and reduce the penetration of dust and water.
Versatile, the 520SRX2 is aimed at riders looking for a robust chain for both urban use and off-road outings. It is particularly suitable for the machines listed in compatibility, such as KTM 690 SMC R, YAMAHA YZ 450 F, or HONDA CRF 300 L (check the number of links and installation).
Maintenance: regularly check the tension, clean and lubricate the QX-Ring seal to preserve internal lubrication, and monitor the wear of the links and sprocket. Installation and adjustment by a professional is recommended if necessary.
