EK CHAIN 525MVXZ2 QX - Ring 525 Universal ChainRef : EKC02952A / 1147821011

EK 525MVXZ2 QX-Ring Chain 525 (manufacturer part number: 525MVXZ2-STL 102 MLJ) — a robust transmission chain designed for demanding riders. Built around low-friction QX seals, it combines perforated side plates and large diameter pins to limit oscillating masses and promote controlled wear. The result: a chain focused on longevity and performance, suitable for urban use as well as light road and off-road outings.

• Type: QX-Ring
• Pitch: 525
• Number of links: 102
• Color: steel / steel
• Stated weight: 1.89 kg / 100 links
• Relative lifespan index (100 links): 3500

The lightweight plate design reduces the forces transmitted to the sprocket and the crown, while the heavier pins enhance resistance to torque stresses. The QX seals minimize internal friction and contribute to more effective lubrication between links — key requirements for the maintenance and performance of the transmission.

Versatile, it is suitable for roadsters, trails, sport bikes, and even quads, making it a serious option to replace an original chain on recent models. Ideal for riders seeking reliability and durability without compromising the smoothness of the transmission.

Common compatibilities: KTM 1390 Super Duke R EVO, Ducati Diavel V4, Honda NT1100 (check the number of links and fitment on your motorcycle before installation).
