I don’t know if anyone has found the absolute limit in terms of burst current with adequate cooling, but the vesc6 can do at least ~80 amps continuous with minimal cooling other than free air. I’d take Hobbyking’s ratings with a grain of salt too, since the rating of a motor is basically its ability to withstand and reject heat - more cooling means more power rating. More copper means more burst rating. I doubt they’ve added much more copper or managed to add a cooling fan, so I’d be skeptical of a 60% power rating increase.
With large enough battery, vesc6 plus a 6374, I think the vesc will win if given enough cooling.
Of course unless you’re going up a 50% grade at 50km/h for a few km continuously, I think you’ll be safe.
