The CDI unit typically features a 4+2 pin connector configuration. Below is the standard functional breakdown of these pins: Exciter Coil (Power Input):

The Honda Unicorn (specifically models like the ) utilizes a highly structured ignition system where the Capacitor Discharge Ignition (CDI) unit acts as the "brain," coordinating timing between the stator and the ignition coil.

The Honda Unicorn (specifically models like the CBF 150) uses a Capacitor Discharge Ignition (CDI) system that is central to its engine timing and spark generation
