Voltage Regulator rectifier to fit:

Voltage Rectifier regulator Peugeot Piaggio 125 250 400 500 Aprilia Gilera 434406003.

Came off bike working. Discovered bike had other electrical wiring problem, not voltage regulator rectifier. Had already ordered and fit replacement, so no point in pulling the bike apart to put this one back on again. My loss, your gain.
