Jesse James made a trike using a diesel engine from a semi. Initially, he had planned to make a motorcycle but realized that weight of the engine would have made a two-wheeled motorcycle too heavy to return to vertical if it ever tipped. I remember him cackling about the whole project and proclaiming “this is just pointless.” That didn’t stop him though and the resulting vehicle was pretty cool.
Saw a trike at the Oakland Roadster Show many, many, moons ago.
It was a jet engine with an extended front end. Kinda had this feeling that it really didn’t work. But, what an imaginary ride!
