Regulator / Rectifier with flasher relay (red plug) – stable 12V onboard voltage for Derbi, Aprilia & Gilera

This voltage regulator / rectifier with integrated flasher relay (red plug, 6 connectors) ensures that the alternating current (AC) generated by the alternator is reliably converted into the 12V direct current (DC) required by the onboard system. At the same time, the regulator keeps the voltage within a defined tolerance range – this ensures the battery is charged correctly and sensitive consumers such as light bulbs are protected from overvoltage.

Especially for models such as Derbi Senda 50, Aprilia RX 50, or Gilera RCR 50, a properly regulating rectifier is crucial for reliable electronics, stable turn signal function, and fewer failures.
