NC law stated max speed for school buses was 45 mph, but I believe it was changed to 55 mph in the last few years. Anyways, there are a few ways for manufacturers to do that, one is with an add on speed limiter, the other is by gearing the bus so that engine red line coincides with the speed limit.
The easiest way to get past this issue is to buy a bus from outside NC. The cost of the bus isn't much different, and any difference is moot when you're spending another grand plus to get a reasonable speed.
