The EK/PBR 520MVXZ2 17/39 chain kit is designed for roadster riders looking for a robust, reliable transmission solution that closely matches original specifications. The EK MVXZ chain, equipped with QX seals, combines degreased plates with lightweight holes, large diameter pins, and low-friction seals to minimize wear. The kit includes the standard sprocket and the 17/39 sized pinion, ready to replace your original transmission.
Designed as an OEM replacement solution for roadsters (specifically road bikes in the 600–1100 cm³ range), the MVXZ stands out for its balance between lightweight and strength. The lightweight holes optimize unsprung mass, while the reinforced pins enhance torque handling. To maintain longevity: check the tension, monitor wear, and lubricate regularly according to your usage (road, duo, luggage). Compatibility examples: HONDA NC 750 X (RC72/RC90) — however, please verify the pitch and number of teeth before installation.
