I realize that this is kind of a necro-post, but felt I had to comment on this post. Firstly, McQueen truly was the king of cool, long before the mainstream media "rediscovered" him. He was cool, not for his style, but because he was a proud motorcycle enthusiast in a time when motorcycling was a fringe lifestyle, we were second-class citizens and most Americans knew nothing of motorcycling beyond the hells angels. He was an enthusiast in a time when being a "biker" could be damaging to his career.
Secondly, an enthusiast, especially one like McQueen will ride anything with two wheels for the sheer thrill of riding a bike, even if it was a pink moped with a basket on the front and streamers on the handlebar. A true enthusiast isn't embarrassed by any bike! If you are, check your leathers at the door!
