An electronic ignition and alarm system for motorcycles. An electronic circuit (22) for reading a coded signal emitted by a code-generating integrated circuit (18) inside the ignition key (19), can be connected inductively or by electric contact means to a microcontroller (21) programmed to enabling the operation of the ignition circuit (10) of the engine after identification of the coded-signal. The coded- signal reader (22) and the microcontroller (21) are fed by a power source (23) comprising a capacitor (C3) for storing the energy supplied by the voltage generator of the ignition circuit (10) of the motorcycle. The energy storage capacitor (C3) can be connected to the voltage generator (11) via a first low-impedance circuit comprising an electronic trigger switch (T1) deactivated by a control circuit (33) which controls the charging voltage of the energy storage capacitor (C3) upon start-up of the engine, before activation or the ignition circuit (10), or, respectively, via a high-impedance circuit (34) which maintains the charging voltage of the capacitor (C3) to reduce current drainage of the voltage generator (11) by the capacitor (C3) during running of the engine.
