This generation bike right? Its barely the headlight height of a truck. That's a mini bike in my book.

But the easiest test you can take is trying to clear a double with a full-size adult on the vehicle that should be easily done an a 125 2-stroke or 250 4-stroke bike. There's some AMA classification ruling as well, but I don't feel like digging up.

I think you're confusing a motocross bike with a dirtbike. Dirtbikes are motorcycles you ride in the dirt. Motocross, enduro, off-road, etc are sub classes of dirtbikes.

Kind of like motards, sportbikes, cruisers, standards etc are sub classes of street bikes.
