Interesting observation. To me the Triumph twins are some of the best looking bikes on the market. We have a couple of late 60's TR6C's that we're going to restore and I really think the new Hinkley twins are a pretty close approximation of the older bikes, style wise of course. The new ones don't leak oil or suffer from random electrical failure.
I've never been a fan of the cruiser look, Harleys don't do much for me and the metric clones do even less. To me a Ducati, any Ducati, followed closely by MV Agusta are the epitome of bike art. I only ride a cruiser style bike due to the fact that my old body isn't tolerant of the riding position dictated by a proper motorcycle.
So there ya go. The old different strokes thing. That's why its great there are so many choices out there.
