Performance and handling between the 07 Tourer and the 08 Touring models? Only my imagination, at this time, could tell me that the 07 is much much more spunky. I've not had the pleasure of a Touring test ride. The torque is up and the Hp is down and the back tire is cheaper on the 08. The back tire, by the way, is a significant and regular outlay for the hot Rocket III. Several avid riders, and I very soon, have gone over to the "dark side" with car tires.
