I just don't get it. Sure, the bike is gorgeous, a museum piece.
Pure aesthetics. In all honesty, those are difficult to judge, because they are both highly individual and extremely faddish. The bustle was once the height of fashion. Then, it wasn't. Choppers came and went, and have came again. Aesthetics change. They're just style.
Form follows function. Appreciating something based, first, on it's functionality, is different. The shaker hood on a '70 Road Runner with six-pack aspiration is functional. That gives it a beauty, beyond some bogus piece of fiberglass stuck on a hood, just for looks. When I was a kid, drag racing my way through youth, if it wasn't functional, it wasn't cool.
Functional was the highest compliment to machinery.
If you're looking for functionality within your basis of aesthetics, then you're often going to be disappointed by others' opinions, when they're purely based in style. The bustle, like the chopper, isn't really good for anything.
But can you imagine how awful it would be to ride? Isn't that a basic element of being a motorcycle enthusiast? You like to ride..
Choppers are awful to ride. I like to ride, and when I was young, there used to be a raked-out Harley chopper parked in my Uncle's front yard. I rode it. I rode it, all the time. Nobody else would. It was cool, but it was awful to ride. Still, I liked to ride it. It was awful.
I've rode a few, in the years since. They were awful, too. I'll never buy one, but it was fun to try them. I particularly liked the part where I got off the things, and then cussed them... The paint jobs were sometimes neat, though.
Just because you like to ride, doesn't mean a person wants a highly functional motorcycle, or that they're going to cover a lot of distance with it. There are those, who are going to suffer with whatever failures a machine has, either because they don't know any better, or are so taken with form that they endure the lack of function.
If you just want to look at it and hear the motor rev, you're not a motorcyclist. I don't know what that is, but it's not a motorcyclist.
You're a motorcycle enthusiast. If you were a motocyclist, you'd ride the thing. Even if it were awful.
