The Vulcan 900 is the epitome is 'one size fits all'. It's a bike that really can do just about anything, at least halfway. It can tour across the country for thousands of miles with trailer in tow, it can cram along urban streets and fight traffic, it can carve up corners. It can't do the long haul like a goldwing or the urban streets like a scooter or the corners like a sportbike, but it does an excellent job of being a capable bike in any situation, even if it's not the best bike for the situation.
It's also, in my mind, the PERFECT beginners bike. This was my first bike. It's a bike that was tame and easy, and I could learn on. But, not, I can and have taken it all around the state, and neighboring states, on trips lasting hundreds of miles. A big fuel tank, decent size to the bike, and great fuel economy makes it an excellent tourer. With hard bags and a trunk, the wife and I have taken this bad boy all over the place. We've packed for weeks onto the bike, including laptop, DSLR Camera, enough clothes to not have to do laundry once, and rode interstates, back roads, and everything in between on the way to our various destinations. Not many bikes can do that, do it comfortably, and STILL be something a new rider can learn on.
