Oomp.......I chose the Fatboy because I wanted a simple bike that I could do a nice passenger setup on, also, I liked the solid wheels.
The reason for the change to the Ultra Classic is so that we will have more space for luggage and stuff for overnighters.....also, the UC is a bit more comfortable (because of the fairing) at interstate speeds. When your at the HD dealer check out a UC Screamin Eagle, you'll see what I mean. The main difference between the Road King and the UC is the fairing (with stereo, GPS, CB radio) and storage space.
