Well, that depends.

Many manufacturers don't advertise the watt and amp ratings of their motors. However, Novak and LRP do. Anything in the range of 4000KV from those companies is rated around 200-300 watts (300 watts being the high end I could find in a 4000KV motor, most were much closer to 200 watts, one was actually 180). Even at 300 watts at 7.4 volts (2S Li-Po) that is only 40 amps. So assuming you use the motor in a application (with the correct gearing) to stay within it's rated parameters, the 60Amp speed control would technically have no problem.

Many people push gearing and temps pretty far, so I suppose the more head room you have the better, but there is too much in play to make a general statement that a 60 Amp speed control would have trouble with a 4000KV 540 motor.

Also, I recently checked the amp draw of my Novak Havok 8.5 turn (5000KV) in my TC3 to make sure it wasn't drawing too hard for a Li-Po I wanted to use. I measured a peak of 30.45 amps at around 8 volts (fully charged 2S Li-Po). That's a 5000KV motor geared properly for the situation and the amperage falls well within the rating of a 60Amp ESC.
