After 2 years with My B King I have come to the conclusion that it is a great bike and has been a lot of fun but is just a bit too much like my Busa. So I am at the very beginning of planning a change. Because of my size I would like to stay in the 1 liter class. I prefer an upright position. (I owned a 999 for 4 years and it was fun the superbike crouch is over for me) At the moment my two top picks are the the Aprillia Tuono V4r and the Ducati Streetfighter. I would welcome feed back from people with saddle time on these machines.
