Speaking of Harleys, I have to say that my view on them has evolved quite a bit over the years. A friend of a friend finally clued me in to a fundamental aspect of appeal that I had missed earlier:
Complete customization. Instead of riding the exact same bike as 50,000 other guys/gals, you can completely customize the bike to be a one-off that is unlike many (or any) other--not just in chrome farkle, but down to fundamental engine parts.
Harleys (IMO) are the ultimate tinker toy bike that can be taken apart and reconstructed in almost any form you like.
As I've stated here previously, I'd personally prefer an Indian over a Harley, but if I *were* to own a Harley, it would be a V Rod:
Which sports a liquid cooled Porsche designed motor, BTW...
