My wife has an 07 UC CVO and I have the 10 UC Limited. We both love our bikes because we have modified them to "fit" us. My 10 with 2 into 1 pipe, 255 cams & PC V with auto tunes will run circles around her 110, but she consistently gets 5-10 mpg better than me. If you like your 07, you will love the 103 and the new chassis that came out in 09 in the 2011 Limited. Go for it, you won't be sorry.
