Hm. I'm not clear on how you'd tell them apart, since they're likely identical two-stroke motors; though it should be trivial if the illegal dirt bikes illegally don't have proper mufflers, presumably if it were trivial you'd already be able to.
It's plausible that you could tell their shifting patterns apart, since the dirt bikes are probably geared lower, and the scooters may have automatic transmissions.
