Electrosport Industries Rotor #ESF901 Honda CB750/CB650/CB900/CB1000/Nighthawk
Product Details
Brand new replacement rotor for the alternator system on vintage Honda motorcycles. The OEM Honda rotor is prone to failure and Electrosport developed this high-quality replacement part as a direct bolt-in replacement. It comes with a full one year manufacturer's warranty.
Stock-style replacement rotor with an average resistance of 5.5 Ohms when new
Check the OE rotor resistance between the slip rings with a multimeter
If it is less than 4.3 Ohms the rotor is bad
No charge to the battery is a typical symptom of a bad rotor
Often when the rotor fails due to internal shorting (resistance less than 2 Ohms) it will also take out the voltage regulator/rectifier
We highly recommend the replacement of the regulator/rectifier as well upon installation of this rotor to be sure all systems are good on your bike
