2010 KAWASAKI VULCAN 900 CUSTOM, It s called Custom because this is how riders did it back when they rolled their own: A flat handlebar sits in custom clamps atop distinctive forks that hold a tall, slender custom-looking front wheel. A bobbed (as in shortened) rear fender perches over a fat tire, and cool, clean components fill out the middle including a rumbling fuel-injected 903cc V-twin exhaling through dual slash-cut exhausts, a low gunfighter-style seat and forward-mounted footpegs complete its rakish image.
