EK 525MVXZ2 QX-Ring Transmission Chain — Manufacturer Reference: 525MVXZ2-G/G 104 MLJ

Designed by EK CHAIN for demanding riders, this 525 MVXZ chain equipped with QX seals is intended for road machines and sporty trail/roadsters seeking reliability and longevity. The side plates feature lightening holes to reduce rotating mass, while the larger diameter pins enhance strength under stress. The QX seals minimize friction and contribute to better lubricant retention between the links.

Versatile, it is suitable for urban, touring, sport, enduro, and vintage environments — useful for replacing the OEM on high-displacement machines such as the KTM 1390 Super Duke R EVO, Ducati Diavel V4, or Honda NT1100 (examples of compatibility). EK indicates a lifespan superior to that of a standard O-ring chain, according to its internal tests.
