EK 525MVXZ2 QX-Ring 525 — Manufacturer part number: 525MVXZ2-STL 112 MLJ. High-quality drive chain by EK CHAIN, designed to replace original sets on roadsters, trails, and sportbikes equipped with a pitch of 525. Its robust construction and QX seals limit friction losses for better final drive efficiency.

• Pitch: 525
• Number of links: 112
• Color: steel / steel
• Weight: 1.89 kg (for 100 links)
• Technology: lightweight side plates, large diameter pins, and QX seals reducing friction

The MVXZ design focuses on lightweight side plates and reinforced pins to combine reliability with reduced inertia. The QX seals enhance internal lubrication and decrease wear from friction — which can, depending on usage conditions and maintenance, extend the lifespan compared to a standard O-ring chain.

Versatile, it caters to Urban, Roadster, Trail/Adventure, Sport/Racing, Enduro, Supermoto, Cross, Trial, Touring, Vintage/Classic, and Quad environments. Examples of compatible mounts: KTM 1390 SUPER DUKE R EVO (2025), DUCATI DIAVEL V4 (2025), HONDA NT 1100 (2025).

Ideal for those seeking a high-performance and durable replacement chain for their final drive — to be paired with a well-maintained sprocket and rear sprocket, along with regular maintenance (lubrication and tension checks).
