Big V-Twin comparison motorcycle review

Take five motorcycles. All but one are V-Twins (10 years ago an endangered species, now one of the dominant motorcycle engines). All sized from 1100 to 1500cc, all weighing 550 or more. All with four or five gears, none with seat heights above 29 inches. They're painted different colors, but if you think that we can't tell them apart by anything other than the paint -- well, you're pleasantly wrong. How different can they be? That's the question non-cruiser aficionados always ask, and it's usually answered one way "If you have to ask, you don't understand."
