Thanks to Joe W. and others for I.D.ing the more angular sidecar as a Motorvation Formula II. The PO told me it had been mounted on a BMW. It is missing some mounting hardware. This is not a keeper and will get sold. The white repainted Cali and other sidecar setup is a new toy, and work in progress. Hahnda is right to say much work was done and there is evidence of miles being put on the rig. That leading link front end is a "Unit Forks" is an aftermarket set up. 16" front and rear wheels, 13" on the white sidecar. The white car is likely some incarnation of a Spirit Eagle car - but - some other brands are very similar. The bike does not run yet - bought it dead - a pig in a poke. First step will be the un-rats-nesting of the wires. The tip off is the twist on wire nuts everywhere. I'm a crimp & solder & heat shrink kind of guy. It's good to prevent unscheduled fireworks. No rush. Any further thoughts or ideas are welcome.
