A dolly includes a first platform that has a central longitudinal axis and monolithically formed outer and inner side portions extending outwardly and at an oblique angle therefrom. The side portions further extend along a length of the axis for retaining a motorcycle upon the first platform. Rectilinear arms have opposed ends wherein one end of each arm is conjoined to the first platform, and converges outwardly therefrom. A trapezoidal shaped second platform is spaced from the first platform and has a surface area less than a surface area of the first platform. The second platform is conjoined to another end of the arms such that the first and second platforms maintain a fixed spatial relationship. Coextensive casters are conjoined to the first and second platforms respectively. Mechanism is included for locking selected casters, preventing the dolly from freely articulating about a predetermined arcuate path.
