ESR539 is a high quality regulator/rectifier that has been specifically designed to replace the unreliable OEM part on the Suzuki DL1000 model.

Our ESR539 incorporates a very efficient heat sink which keeps the temperature of the unit down. 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 this unit also comes with a full one year warranty.

Please Note:

1. All electrical components must be fitted by a qualified technician.
2. Before fitting electrical components ensure the root cause of the original failure has been addressed.
3. The absence of either of points 1 or 2 above will void any warranty.
