ESR100 is a high quality regulator/rectifier that replaces the not-so-reliable OEM regulator on many older Suzukis. Power handling of our ESR100 regulator/rectfier is superior, and this part is a plug in replacement on many Suzuki models. We have incorporated a heat sink that gets rid of internal heat to the housing quickly and efficiently, making for a very reliable unit. This regulator/rectifier regulates all three phases coming from the stator, unlike the stock unit which only regulates 1 or 2 phases (depending on the model). Three phase regulation is a major step towards reliability on these Suzuki GS models. Like all regulator/rectifiers manufactured by ElectroSport ESR100 also comes with a full one year warranty.
