Also, on the kershaw designs website I see they have motor bearings rated for 70,000 rpm and 100,000 rpm. What would happen in real life with those rpm speeds?

My personal opinion (I have a mechanical & electronic engineering background) is that the XL motors and in particular the 540/550 sized motors are too large to spin t those extreme rpms. The balancing on the motors would have to be much more precise and even then there would be problems. Smaller motors can spin faster with better success.
Remember too that hi-rpms are VERY requiring on the ESC as well. Processing at 75,000rpm is far more demanding (and not possible on certain ESC's) that at 25,00rpm.
