ElectroSport Regulator/Rectifier - ESR240

ESR240 is a modern high quality regulator/rectifier which replaces both the original rectifier bridge on the 1970-1979 Honda CB four-cylinder models, as well as the mechanical regulator. Both these units are replaced with this single modern solid state regulator/rectifier.

The ESR240 offers a much more stable voltage output at the battery compared to using the outdated OEM components. Like all other regulator/rectifiers and stators manufactured by ElectroSport we offer ESR240 with a full one year warranty.

ESR240 fits: CB400F, CB500F, CB550F, CB550K, CB750F, CB750K, which are all models with a single overhead camshaft. It is designed to be a plug in replacement for these models.

Features:

• High quality and better-than-OEM regulator/rectifier
• We built these stators using the latest technology in regulator circuitry, and use a very efficient heat sink to get rid of the heat quickly and efficiently
• Controls the output voltage very accurately resulting in a perfect charge rate for your battery across the RPM range
• Thanks to the modern power circuits it runs much cooler than the OEM unit which drastically improves reliability compared to stock
• 1-year manufacturer's warranty
