1%er - If you read the papers or listen to the news, the media and law enforcement agents have redefined the term "1%er". The term was first used in the 60ís to describe some of the people that attended the motorcycle events back then. The AMA (American Motorcycle Association) stated that 99% of the people at their events were God fearing and family oriented. The other 1% were hard riding, hard partying, non mainstream type people. Thus the term 1%er was born. Some of the early bikers embraced the term and decided to call themselves 1%ers. It did not mean that they were law breakers or low life individuals. They were simply men that rode their motorcycles seven days a week in all kinds of weather, liked to drink and raise a little hell.
