Regulator & rectifier: Stable voltage for your on-board electronics

The voltage regulator (often in combination with a rectifier) is the guardian of your on-board electronics. It converts the alternating current generated by the alternator into direct current for the battery and limits the voltage so that light bulbs do not burn out. If your lights are flickering, bulbs are constantly breaking or the battery is no longer charging, the regulator is often to blame.

In this category you will find high-quality replacements: from original Piaggio regulators and proven OEM parts from Ducati Energia to our high-performance bgm PRO universal regulators, which are also perfect for converting vintage bikes to modern 12V ignitions. Protect your electrics from overvoltage and ensure a permanently bright light.
