EK 520H Transmission Chain — Manufacturer Reference: 520H-STL 98 SPJ
Designed by EK CHAIN, this 520H chain is aimed at riders of roadsters, urban bikes, motocross, and quads who seek a robust and easy-to-install transmission. Manufactured according to EK Japan standards, it offers a suitable compromise between longevity and cost for a wide range of motorcycles from 125 to 400 cc and beyond.
This reference is suitable as a standard replacement for many motorcycles. Before installation, check the pitch (520) and the number of links required for your setup, then make the length adjustment and riveting according to the manufacturer's recommendations or a qualified workshop.
Examples of compatible models: TRIUMPH SPEED 400 (2025), ZONTES 125Z2 (2025), KTM 125 DUKE ABS (2025). To maintain an efficient transmission, regularly service the chain and sprocket: cleaning, lubrication, and tension checking are essential.
