This universal 5-wire CDI (capacitor ignition diode) is suitable for a wide variety of small and medium-displacement motorcycles, off-road vehicles (trail/racing machines), quads, and ATVs. As a central component of the ignition system, it receives ignition pulses and delivers high voltage to the ignition coil at the precise moment of spark generation. Thanks to its high compatibility, stable performance, and simple plug-and-play design, this CDI is ideal for replacing an old or faulty original CDI, as well as for restoring or optimizing engine ignition.
