Dear Mr. Tank:

This is in reply to your letter of December 29, 1986, with respect to the definition of "motorcycle" for purposes of compliance with the Federal motor vehicle safety standards. You have asked whether a vehicle with two wheels at the front, and one at the rear with two tires mounted on it, would still be regarded as a motorcycle.

The definition of a motorcycle is "a motor vehicle with motive power having a seat or saddle for the use of the rider and designed to travel on not more than three wheels in contact with the ground." This is technically inaccurate in part because wheels do not contact the ground. I believe that the drafter of the definition meant to say "tires" rather than "wheels." Thus the configuration about which you have asked is one in which four tires contact the ground, and we therefore conclude that such a vehi cle would not be regarded as a motorcycle.

Sincerely,

Erika Z. Jones Chief Counsel

Chief Counsel National Highway Traffic Safety Adm. 400 Seventh Street SW Washington, D.C. 20590

Dear Sir:

I have communicated with George Shifflett in the Department regarding our three wheel vehicle. According to your standards, we are governed by the laws specifically addressed to motorcycles. The question was raised, if the three wheel vehicle had two whe els in the front with one in the rear, the rear rim having two tires mounted on it, would it still be regarded as a motorcycle.. I have enclosed three photos that will visually explain our proposed application.

I would appreciate your opinion on the additional tire effect on our motorcycle classification.

Sincerely,

Allen R. Tank President
