The Rocket III. One man's ugly is another man's distinct. You certainly can't say it looks like just another generic harley rip off.
That being said the VTX is a nice bike. I haven't ridden one but I raced a friend on his 1300 once and he ate my lunch (I would have been surprised if it had even been a contest - the VTX has a half-liter on mine and I'm carrying an extra c-note over the other rider).
