I may be flying solo here (I'm sure Martino thinks so), but I still think his bike deserves lots of consideration. A hard tail SOHC/4 is unique, as is the suicide shifter, but what stands out to me is his desire to ride it. I favor bikes that get ridden lots, and a hard tail requires a certain determination and insanity. I hear what you say, MMICAFE, Martino's bike doesn't have the chopper sound, but I'm not really into the chopper sound.
I'd dare say it's fair to guess that the other nominees have spent more time and attention to detail. They are drop dead gorgeous bikes, which is why I said I hate this thread.
