It's possible to build a motorcycle sidecar. With the right tools and design, an extra passenger seat can be created and fitted to any motorcycle type.
To build a motorcycle sidecar, make a basic frame that can support both the structure of the sidecar and the weight of the passenger.. Although a frame can be hand-welded, pre-made frames or trailer hitches exist. The body of the sidecar itself is typically made out of plywood that is curved and sanded into shape. It should be aerodynamically designed for smooth driving. Wheels and an axle attach to the back, and a link attaches to the side to connect the sidecar to the motorcycle. A sidecar made by professionals may provide greater safety than a homemade one.
