Review on 🔌 Enhance Riding Performance with ElectroSport ESF901 Rotor for Honda CB900F by Jack Bhowmik

I may know that the rotor for CB900 does not fit my '79 CB750K but so far everything I have found suggests this block should fit. But that's not the case. It's about 2.5mm "higher" than my original and rubbed on the screw covers that hold the brushes. I wasn't too impressed with the "lines" separating the two slip rings either, it looks like they were drawn by a five year old. The device stopped working after about 20 seconds when the battery voltage returned to a constant 12.6V regardless of RPM. But other than that, this dandy is worth about a star as a fishing weight. I hope there are no problems with the return, but we'll see.
