I've got a Kawasaki 500. It is formally called a 1973 Mach III (H1) three cylinder two stroke. Some people called them widow makers due to unexpected wheelies in the middle of fast turns (like freeway on ramps). I guess you are referring to another model.
OK, you have lots of beginner bike suggestions; my suggestion is about continuing street smarts education. 1) get every book David Hough has written and go to bed with each night. 2) subscribe to Motorcycle Consumer News. And when (if) you graduate to a LARGE (700 lbs and up) touring bike, get Jerry Palladino's Ride Like a Pro DVD. Worth 100 times the price. As he points out, don't get 20 years experience by repeating the first year's 19 times. Continuing education or possibly die too soon. (On my 17th motorcycle).
