EK 520MVXZ2 QX-Ring Transmission Chain — Manufacturer Ref: 520MVXZ2-STL 118 MLJ. Designed by EK CHAIN, this 520 QX-ring chain is aimed at riders looking for a robust and reliable replacement part for their transmission. Its careful construction combines lightweight plates, large diameter pins, and QX seals to minimize friction losses and optimize the overall longevity.

Suitable for both urban use and off-road outings, it fits roadsters, trails, sports bikes, or vintage machines requiring a 520 chain with 118 links.

• Pitch: 520
• Number of links: 118
• Color: steel / steel
• Weight: 1.74 kg (for 100 links)
• Type of seal: QX-Ring, designed to reduce friction
• Relative lifespan: 3400 (value given for 100 links)

The lightweight hole plates reduce unsprung mass, while the larger diameter pins enhance rolling resistance under load. Whether you're riding in the city, on winding roads, or in more demanding terrain, this chain provides a solid foundation for transmission — to be regularly maintained (tension and lubrication) to get the best performance.

Common compatibilities: KTM 690 SMC R, Honda CRF 300 L, Ducati 950 Hypermotard SP, and other machines accepting the 520 pitch with 118 links.
