Motorcycles have come a long way since then and so has safety gear but they all, for the most part, still seem to have two wheels (well, except the Piaggo MP3). Of course, we as the riders haven't progressed at all. We still go out and do stupid things that we regret later.
I used to hill climb with a 1970 TR6R (650 cc) with a friend who had a 441 Victor on a hill that was easily as steep as the one in the film. I tipped over quite a bit. I never even thought about scratching the bike. 38 years later, I go bonkers at the slightest imperfection.
