The SRX2 chain, a recognized reference from EK, fits roadsters and small displacement models — for example, the KTM 200 DUKE ABS — when the 14/42 ratio and 110 links are compatible with your vehicle. Ideal for a complete overhaul of the final drive, this kit allows you to start fresh on a reliable base after the wear of the original equipment.
