ESR538 is a high quality regulator/rectifier that has been specifically designed to replace the OEM part on various Ducati models. As such it is also a direct plug-in replacement.

Our ESR538 incorporates a very efficient heat sink which keeps the temperature of the unit down and internally we use only the best quality components for the power circuits. The result is a very high quality unit that is far superior to the OEM regulator.

This regulator/rectifier controls output power accurately and provides for a stable charge rate of the battery across the whole RPM range.

Like all regulator/rectifiers and stators manufactured by ElectroSport our ESR538 also comes with a full one year warranty.
