'One Percent' is a term coined after a gathering of the American Motorcycle Association's 'Gypsy Tour'. On July 4, 1947, 3000 riders descended on Hollister, California which was sponsoring a 'dirt hill climb'. When violence broke out the American Motorcycle Association issued a statement saying that 99% of riders were respectable, pleasure riders and the other one percent were troublemakers. Since that date many clubs and groups have referred to themselves as the 'one percent'. This category is devoted to sites related to one percent clubs.
