That’s because they’re “black”.

The dirt bike/ATV gangs have become common in urban areas even though there aren’t any trails or open areas for them to ride on.

Check out YouTube for videos on it.

But, yeah. Definitely feral black youths.

You are correct.
Gangs of them roam the Streets of the hood and it appears that the Police are under orders to just ignore them.
All of the motorcycles are unregistered and many of the riders are too young to get a drivers license.

Because they're cheap ($1,000 to $3,000 new), and you can get away with not having a drivers license, insurance, registration, etc. That can make them popular with ferals.
