This Futuristic Motorcycle is called the Cyclere. The body of the vehicle is balanced on a single large sphere that can easily change directions with unlimited uses in tilting, rotating, and driving. Typically used for characters as a fast vehicle in futuristic scenes. The .blend file is included as well.
The pivot point of the car and sphere are aligned perfectly so that they can rotate realistically in animation with little effort.
The .zip file included all the other file formats AS WELL as the textures. So I would advise making that download too.
