The county director of finance may register a motorcycle with an aftermarket motorcycle frame, using the number of the frame as issued by the manufacturer of the frame, the vehicle identification number on the certification label, or a vehicle identification number assigned by the director of finance. A bill of sale and Manufacturer's Statement of Origin for the frame, engine, and transmission must be presented and retained as a part of the permanent county registration records. If a Manufacturer's Statement of Origin is not available for the engine and transmission due to the use of a used or reconstructed engine, transmission, or both, then a bill of sale or other proof of ownership, satisfactory to the director of finance must be presented. Except for motorcycles that are built on an aftermarket motorcycle frame, special interest vehicles, and reconstructed vehicles, any motor vehicle or device that is not certified by the manufacturer to be in compliance with all applicable Federal Motor Vehicle Safety Standards as of the date of [manufacture] shall not be registered.
