EK 525MVXZ2 QX-Ring Chain 525 by EK CHAIN — manufacturer reference 525MVXZ2-G/G 102 MLJ. Designed to meet the needs of demanding riders, this QX-Ring transmission chain combines lightweight side plates, large diameter pins, and QX seals to minimize friction. Ideal as an OEM replacement chain for mid to high displacement motorcycles, it features a gold finish for a sleek look on the bike.

• Type: 525 transmission chain, QX seals
• Number of links: 102
• Color: Gold / Gold
• Weight: 1.89 kg (for 100 links)
• Relative lifespan: 3500 (for 100 links)

The mechanical features — weight-saving holes in the plates and oversized pins — reduce unsprung mass and improve rigidity. The QX seals help limit friction losses and maintain the internal lubrication of the chain. EK indicates a superior longevity, potentially reaching up to 1.5 to 2 times that of a standard O-ring chain, depending on usage and maintenance.

Versatile, it adapts to Urban, Roadster, Trail/Adventure, Sport, Touring, Enduro, Supermoto, Trial, Cross, Vintage, and Quad categories — noted for recent models such as the KTM 1390 Super Duke R EVO, Ducati Diavel V4, or Honda NT 1100. Effectively replaces the sprocket and crown to restore reliable transmission and precise handling.
