ESR124 is a superior regulator/rectifier designed to outperform the Suzuki OEM regulator on SV650 / DL650 and SV1000 models. We built ESR124 around a modern heat sink and we incorporated the newest generation of our control circuitry that offers super stable voltage output across the RPM range. This efficient heat sink dissipates the heat quickly and efficiently making for a very reliable unit. This will be the last regulator you will need on your SV. Like all regulator/rectifiers in our range of products, this ESR124 also comes with a full one year warranty.
