The Bandidos MC (aka Bandidi Nation) outlaw gang came into prominence after a shootout with the Cossacks gang left nine dead, 18 injured, and 170 bikers placed under arrest in Waco, Texas, in 2015. The club has since come out of the American underworld to be declared a Tier-2 gang. This is the second-most dangerous classification by the Texas Department of Public Safety.

Bandidos have built a fearsome reputation around their gruesome activities. In the 1970s, the founder Donald Chambers killed two Mexican drug dealers after making them dig their graves. The violence perpetrated by this gang involves turf wars with other biker gangs.

After the Waco shootout, Bandidos are listed as one of the Big Four Outlaw Motorcycle Clubs by the FBI. Apart from violent crimes, this gang traffics drugs across the Mexican-Texas border. It is heavily involved in the distribution of methamphetamine, marijuana, and cocaine.

Pagans MC patch USA

Year Founded – 1957

This biker gang did not start as a crime syndicate. Formed in 1957, Pagans was an ordinary motorcycle club until 1965. After veterans joined the club, it would soon join the ranks of criminal activity thanks to the bitterness against the government by veterans in the 1960s.

Pagans dominate the East Coast. The gang has its share of illegal activities from smuggling of illegal drugs like meth, marijuana, and heroine to organized crime. The gang is also known for random assault of civilians, drive-by shootings of former members, and violent brawls with other biker gangs.

The club identifies as an intricate organization with bylaws and legitimate businesses. But this is only one side of the club because its members are wanted for highway shootings, murder, and racketeering. The gang majorly deals with drug and weapon smuggling in the US and across the Mexican border. In a 2011 raid, eight pounds of methamphetamine, 40 pounds of cocaine and a rocket launcher were seized.

Like other gangs, Vagos also frictions with Hells Angels and has been involved in numerous gang shootouts. The Vagos gang has been infiltrated a few times by the ATF, but efforts to bring them down have not borne fruit. The gang has even won twice against law enforcement in defamation charges.

The biker gangs listed here are just a few of the most notorious outlaw motorcycle clubs in the USA.
