I wasn't meaning to be contentious or demean the article in any way, but that statement did get me wondering if you asked anyone out of the blue: 'What is the world's most famous motorcycle?' what would be the answer?
Even as a rider of many years I still would struggle for an answer. With regard to the subject at hand, I see an iconic movie still, but possibly greater than the sum of it's parts. Why would that one bike be more 'famous' than the other? Why isn't Peter Fond the: 'World's most famous actor?' Is Max Von Sydow standing under the: 'World's most famous streetlight' in a similarly iconic movie poster?
Also, having never seen the film, I was expecting a link to Marvel Comics given the: 'Captain America' name, so that's something else I've learned today..
If asked to recall a 'named' motorcycle I could only venture: 'Slippery Sam', but wouldn't put that on a: 'Most Famous' pedestal. The BSA in 'Goldfinger' ? T.E. Lawrence's Broughs? (but which one?)
And I expect a strong case could be made for the Honda C90, perhaps??
