Voltage regulator -4-pin 12V (G-G-G-ground)- Vespa Cosa (without battery), PK XL2

12V voltage regulator 4-pin for Vespa Cosa and PK XL2

UPDATE NOW!

The bgm PRO regulator (Art. No.: BGM6690) is a very nice alternative to the conventional voltage regulators. Not only does it supply either alternating current or direct current, it can even provide a stabilized voltage via an integrated circuit. This means that no matter what load is applied, the voltage always remains the same,

so no more flickering lights when the indicators are switched on etc.

The perfect update for modern on-board electronics. More space-saving than the original large boxes. The perfect replacement for all voltage regulators, whether original or from aftermarket ignition systems such as the Vespa and Variotronic. If you want to charge your cell phone or operate a navigation system while driving, you won't want to be without this regulator!
