I know this isnt a "new" idea, but I was thinking about this the past couple of days:
take a 1000cc bike (or around that size)
then take a small, light RWD car such as a Miata, from a junk yard or something, nothing with major damage and obviously doesnt need the engine, basically a shell.

then transplant the bike's engine into the Miata, run a chain/sprocket to the rear, while removing the rear drive axle, replacing it with just a straight axle and sprocket welded on. (unless its shaft driven, which might work better)

not sure if the trans of the bike is strong enough here, but if it were, what do you think ?
I got the idea from someone posting about the car that got insane mileage that was built the same way, but with (I think) a heavier car.
