Well, expect some hot temps. The general rule of thumb is to keep those motors at or under 35k rpm. But that depends on how much top speed running you plan to do. If you hit max speed rarely, then you might be ok. If you're doing speed runs, there might be issues. If the motor gets too hot, you will demagnetize the rotor and then you'll have no power and the motor will get hot for apparently no reason. Also, I don't know how much centrifugal force the magnets will take before flying apart, not to mention the bearings.
