ESR121 is a superior regulator/rectifier designed to outperform the Suzuki OEM regulator on the DL650 from 2008 onward.

We built ESR121 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 DL650.

Like all regulator/rectifiers in our range of products, this ESR121 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.
