ESR685 is a high quality regulator/rectifier that replaces the OEM regulator on the CBR1100XX Blackbird models. We incorporated our latest generation power circuit inside our very efficient heat sink design resulting in our ESR685 which is superior to the OEM unit on these Blackbirds.
Our ESR685 offers a superbly stable output voltage which means your battery will get the optimum charge at any engine RPM. And thanks to our advanced circuit and heat sink this regulator runs much cooler than the stock unit.
ESR685 is a Plug-In replacement regulator/rectifier that comes with a full one year warranty.
