EK/PBR 520MVXZ2 Chain Kit 15/41 - Standard Sprocket

Designed for roadsters, this EK MVXZ chain kit equipped with QX seals is a robust, performance-oriented replacement solution for 520 transmissions. It combines lightweight perforated side plates, large diameter pins, and specially sized seals to reduce friction between links. The result: a chain built to last and maintain smooth transmission under load.

• Type: 520 chain kit (sprocket 15 / sprocket 41) — standard sprocket
• Number of links: 112
• Color: steel / steel
• Sprocket material: steel
• Weight: 1.74 kg (for 100 links)
• Relative lifespan: index 3400 (varies depending on use and maintenance)

The MVXZ construction with QX seals aims to limit friction losses and extend longevity compared to a standard O-ring chain — potentially achieving, depending on usage and maintenance conditions, 1.5 to 2× the lifespan. Kit suitable for touring and roadster bikes; perfect fit to replace an OEM chain.
