The motorcycle was displayed at fairs and circuses around the eastern U.S.. Europeans also had their hand in popularizing motorcycles and, during the World Wars, motorcycles functioned as a quick means of transportation. br br As the motorcycle progressed, the engines and frames became bigger, sleeker, faster and more powerful, resulting in the high-tech and expensive motorcycles of today.
