What does "1 Percenter" signify in the context of motorcycle gangs?

In the context of motorcycle gangs, the term "1 Percenter" signifies an outlaw motorcycle gang member. This terminology originated following a 1947 event in Hollister, California, where a violent motorcycle rally led the American Motorcyclist Association (AMA) to declare that 99% of motorcyclists are law-abiding citizens. Consequently, the remaining 1% were identified as those who engage in illegal activities and are often part of outlaw motorcycle clubs. Members of these outlaw gangs embrace this label with pride, signifying their rejection of mainstream norms and their commitment to a lifestyle that may include various criminal enterprises. This identity is central to the culture and ethos of such motorcycle gangs, distinguishing them from other motorcycle enthusiasts who do not partake in criminal activities.
