Usually, from what I have seen, the US DOT/EPA certify a whole slew of bikes every year. There is a PDF that comes out once a year with hundreds of models and the engines they have, as well as multiple number of other models that share the same engine (usually in name, but like in the case of scooters, entirely other models) that are certified.

They even list bikes certified as CARB certified or 49-state (Californians need not apply) legal. To be honest, I do not remember seeing the Hawk as certified, but if it is, it would be legal for 49 states. Sometimes the problem comes from the names these come under, as sometimes they are certified under a certain name straight after the Chinese factory, while distributors slap other names on them.

That is probably the case here.
