A streetfighter motorcycle is a sport bike that has been stripped of most of the plastics and modified for high performance. The streetfighter motorcycle has its roots in europe, but as Americans have joined the world motorcycle community they have built their own streetfighters to reflect their needs. Streetfighters have brought the custom sportbike scene up to the same level that the custom chopper scene is today. The streetfighter is typically ridden by a more hardcore rider sometimes referred to as a "hooligan". The streetfighter is not just a wrecked sport bike but an intentional custom conversion done to make the bike more ergonomically and performance friendly for an urban environment.
