Dear Mr. Kendall: This is in reply to your letter of February 7, 1979, asking for clarification of S5.1.4 of Motor Vehicle Safety Standard No. 122, *Motorcycle Brake System*. This section requires each three-wheeled motorcycle to be equipped with a parking brake system. You have inquired whether this means a two-wheeled motorcycle equipped with a sidecar.; A two-wheeled motorcycle initially sold with a sidecar attached, o intended to be so sold, is a three-wheeled motorcycle for purposes of compliance with S5.1.4. The fact that a sidecar may be attached to a two-wheeled motorcycle at some point in its existence does not mean that the motorcycle must have a parking brake system when the cycle manufacturer does not intend it to be sold to its first purchaser with a sidecar attached.; Sincerely, Frank Berndt, Acting Chief Counsel
