Highway to Hell
A very early Honda CB750 supplied the power unit - note the kickstarter not seen on later ones. ??? I can see the kick-start lever. You can see one better via this Wikipedia photo: http://en.wikipedia.org/wiki/File:Honda_CB750a.JPG
Actually all SOHC(single overhead cam) CB750's from 1969-1978 have kickers. In 1979 the CB model switched to DOHC (Dual overhead cam) 750 and eliminated the kick starter.
40-41 Willys It is for the bike, which is a Honda twin factory custom from the 1980s but not sure which one yet. The coupe looks more like a '40 Ford.
Honda CM 250 Rebel. Seems to be a long running model which might still be available new although the earlier ones have the front disc on the right and from somewhere in the 1990s it is on the left.
