First Step: Contact the manufacturer (not the dealership) of the motorcycle, such as Honda or Yamaha, and find out if the engine has been certified through the US Environmental Protection Agency (EPA) to meet emission standards for use on the street. If the engine has not been certified for street use, you cannot make the motorcycle street legal."
