Pity I have no more of them to give. They are such a fantastic and efficient beast of a motor, and we know Zero makes and sells a ton of bikes, and people wreck motorcycles as a fact of life, and they often get motors controllers and batteries parted out of them. Parts should be available if you keep hunting around.
And if I could ask- what ARE the different motors Zero makes? I thought they maybe only made two, but I'll admit I never did a deep dive.
As of now there are only 3 different motors, 75-5, 75-7 and 75-10. Not sure if they still make a 75-7R?
They are all IPM motors.
Before it was:
75-5, 75-7, 75-7R of which all three came in SPM and IPM configurations. I believe the SPM to IPM switch over was 2016?
The "R" motor just has magnets that can handle higher temps. The 75-5 and 75-7 are identical other than one being slightly wider than the other.
If I remember correctly the newer IPM motors produce more torque and a little better at heat management.
If you want to go even further back there was a 75-7 designed to be used with the old lower voltage bikes of 66V or something.
Also every year or two they received some update but it was something minor like shaft design and phase cable length and cable colour.
So essentially you have two bases, SPM or IPM. Then you have three sizes 5, 7 and 10. And the R for high temp magnets
