Im currently looking through the history of Black 1% clubs and these groups, according to the ATF, stands out : Chosen Few, Thunderguards, Sin City Deciples, Wheels Of Soul, and Outcast. I notice that Thunderguards & Outcast are exclusively Black while the others allow any ethnicity into the club.
So far they have been quite secretive and elusive overall. The biggest is a toss up between Outcast, Wheels of Soul, & Sin City to me. WOS have expanded rapidly in recent years. So far they are the first Black 1% club to be hit with Rico (that im aware of).
WOS have 400 members in 20 states, but Outcast is frequently stated to be in 30 states. Im still having a hard time locating those states completely. I do know they have a chapter in the Gulfport. I seen them riding in person on I-59 once too.
