A motorcycle dolly which rolls upon a flat surface on four lower wheels positioned in a set radius on the flat surface, the dolly including an upper surface adapted to securely receive a rear wheel of a motorcycle while remaining stationary as the rear wheel of the motorcycle is rolled onto the upper surface, the dolly rolling along the flat surface in an arc equal to the set radius, the radius being the equivalent of the distance between the flat surface contact point of a front wheel and the contact point of the rear wheel, wherein the front wheel of the motorcycle remains stationary upon the flat surface, while the rear wheel upon the upper surface of the dolly is pivotal rotated along the radius, sliding the rear of the motorcycle along the flat surface for movement to a stored position.

What is claimed is: 1. A motorcycle dolly adapted to a rear wheel of a motorcycle allowing the rear wheel to be placed upon the dolly to be moved laterally in a pivotal arc having a radius equal to a distance between a front wheel and said rear wheel of said motorcycle, comprises: a dolly platform
What is claimed is: 1. A motorcycle dolly adapted to a rear wheel of a motorcycle allowing the rear wheel to be placed upon the dolly to be moved laterally in a pivotal arc having a radius equal to a distance between a front wheel and said rear wheel of said motorcycle, comprises: a dolly platform having an upper surface defining a wheel groove adapted to receive said rear wheel and two elevated wheel well margins spaced laterally on said platform, said platform also providing a lower surface defining two recessed wheel well cavities; and a front and rear wheel retained within each wheel well cavity by a respective front and rear axle, wherein the longitudinal axis of said front axle is non-colinear with the longitudinal axis of said rear axle, said axles and wheels positioned at a fixed pivot angle within said wheel well cavity forcing said wheels to direct travel of said dolly in said pivotal arc. 2. The dolly, as disclosed in claim 1, said dolly platform further comprising: a tapered front edge and a tapered rear edge between each said elevated wheel well margin, each said elevated wheel well margin set apart from the other at a distance adapted to partially engage said rear wheel, said elevated wheel well margins having an inner surface adapted form partially engaging sides of said rear wheel of said motorcycle. 3. The dolly, as disclosed in claim 1, wherein said recessed wheel well cavities are formed within each said elevated wheel well margin, each said recessed wheel well cavity having a front wheel compartment, a rear wheel compartment and an axle extension compartment between the front and rear wheel compartments, said wheel well compartments provided at the same fixed pivot angle as the axles and wheels; each said wheel is suspended within each front and rear wheel well compartment by each axle, each axle further held within each said wheel well compartment by an inner axle bore between said axis extension compartment and said respective front or rear wheel well compartment at an inner end, and an outer axle bore between said respective wheel well compartment and a respective front edge or a rear edge of said elevate wheel well margin at an outer end; and a retaining means applied to each said outer end and inner end of said axle to hold said axles within said inner and outer axle bores. 4. A motorcycle dolly adapted to a rear wheel of a motorcycle allowing the rear wheel of the motorcycle to be placed upon the dolly to be moved laterally in a pivotal arc having a radius equal to a distance between a front wheel and said rear wheel of said motorcycle, comprises: a dolly platform having an upper surface defining a wheel groove adapted to receive said rear wheel and two elevated wheel well margins spaced laterally on said platform, a tapered front edge and a tapered rear edge between each said elevated wheel well margin, each said elevated lateral wheel well margin set apart from said other at a distance adapted to said width of said rear wheel, said elevated wheel well margins having an inner surface adapted for partially engaging sides of said rear wheel, said platform having a lower surface defining two recessed wheel well cavities and a front and rear wheel retained within each wheel well cavity by a respective front and rear axle, wherein the longitudinal axis of said front axle is non-colinear with the longitudinal axis of said rear axle, said axles and wheels positioned at a fixed pivot angle within said wheel well cavity forcing said wheels to direct travel of said dolly in said pivotal arc, said recessed wheel well cavities formed within each said elevated lateral wheel well margins, each said recessed wheel well cavity having a front wheel compartment, a rear wheel compartment and an axle extension compartment between said front and rear wheel compartments, said wheel well compartments provided at said same fixed pivot angle as said axles and wheels, each said wheel suspended within each front and rear wheel well compartment by said axle, said axle further held within each said wheel well compartment by an inner axle bore between said axle extension compartment and said respective front or rear wheel well compartment at an inner end, and an outer axle bore between said respective wheel well compartment and respective a front edge or a rear edge of said elevated lateral wheel well margin at an outer end, and a retaining means applied to each said outer end and inner end of said axle to hold said axles within said inner and outer axle bores.
