Abstract
Abstract A two-wheel motorcycle trailer has a curved cradle for receiving the rear wheel of a motorcycle. The cradle is secured to the trailer frame and made horizontally pivotal by a swivel assembly. The frame serves to pivotally support the cradle and to connect the trailer to the towing vehicle by means of a draw bar assembly. The trailer can be disassembled into three parts for transfer or storage in the trunk of a standard size automobile. In alternative embodiment, a trailer having three cradles with a common pivot point is provided to hold up to three motorcycles.
