Peak stator temp is dynamic. The highest temp I measured was 216c on a hot day after hard enough riding to purge coolant.
A 220 stator will not burn out at 240c it will just age quicker.
BMW uses 200c magnet wire which is unusual and why all the typical 180c aftermarket stators burn out quickly.
Assuming it is made well, a 220c stator would get my vote of confidence :)
