Since the Black Guerilla Family thread turned into a thread about biker gangs, I've decided to create a seperate thread on this topic.

Hells Angels and to a lesser extent Satudarah are really the only biker gangs of note in Europe (where I come from) and in Canada. In the USA the other big OMG's (Pagans, Outlaws, Bandidos, Mongols, Vagos, Sons of Silence) seem to play a much larger role in organized crime.

It would be interesting to hear from people who have already dealt with biker gangs themselves. Who they think is the most powerful, dangerous, violent,...
The FBI once classes OMG's as the third major type of organized crime in the USA, behind the traditional American mafia and the Eurasian organized crime groups. Is this claim justified (speaking strictly about the US)?
