Captain America: The First Avenger
Harley Davidson? I doubt if this is a real bike. Probably a made for movie replica - lightweight? It is Harley-influenced with the early style fram and forks but later shovelhead or evo style engine. Newer Harley Modified to look older? Would be not difficult. They produce same shit over decades... Hey, you're right... I'm pretty sure it's a WLA with a different engine and a modified seat.
