V-star, unless you are short, skinny, and never plan to exceed 50MPH. If you are REALLY tall, you will not fit on a V-star.
Having said that, I work with a dude that rides one. He's about 6', maybe 260lbs, and built like a linebacker. (He wears a size XXXXL shirt.) He looks like a bear on a tricycle, but it fits him perfectly. He has done several long rides (including a highway run from Fall River to Albany) and absolutely loves it. He got it in lieu of money a dude owed him & didn't have...he figured he'd flip it on CL, but wanted to ride it a bit to make sure it ran properly.
A couple months later, he sold his Vulcan 900.
