I've never seen a motor go bad at that temp unless somthing freekish happend. What ends up destroying the motor is one of three things.
1) The Rotor looses its magnetic force so the motor looses power and starts heating up more because it cant handle the same gearing it once could. If you catch it in time replacing the rotor will keep this from happening. Rotors generally start to wear from long term use or from getting to 200+ more than a couple times. The hotter the rotor gets the more magnatism it looses.
2) The solder in the windings melts, occasionally this can be fixed but warning will robinson, if it got in the wrong spot it will destroy your ESC the next time you plug it in.
3) The Epoxy in the windings has melted. This is the most common reason a motor goes bad from extreme over heating. The epoxy is the same in all motors and melts down at the same temperature so there is really no one motor brand that is more tollerant than others but occasionaly you get a fluke motor that is more or less tollerant that can be from any of the manufactures
All in all I've had the best luck out of Trinity motors
