Most law enforcers and academic experts agree that the largest one-percent motorcycle clubs are a formof organized crime despite their origins as barroom brawlers. A few club goals related to the destruction of rival groups are more or less overtly criminal. Of greater concern to most observers is the manner in which these clubs provide a context for individuals with a high propensity for illegal activity to unite long enough to operate enterprises of varying levels of sophistication. Social isolation from the mainstream intensifies intra-group loyalties as it concentrates members' attention on the underworld. Bikers integrate their private and club lives in an manner that makes the distinction between club-sponsored and other activities problematic. The relationship of these enterprises to the club itself is often murky as is the line between their planned and spontaneous expressive crimes.
