I would love a nice comfy harley to cruise the highway on. The dirtbike riding position on my Honda is great for town and commuting but after a couple hours it gets very tiring. The but in the air style of a sportbike is better for the highway but also is hard on the wrists and you have lousy sight. A nice touring bike with a big windshield like HD's hog would be perfect. I was checking out the Buell Ulysses adventure bike and it looks nifty. It runs a 1200 sporty engine and is like a american version of the BMW GS. The kind of bikes they use for the Dakar etc. Harley and Buell both have fantastic fit and finish as well.
I have put off modding my 919 but one I have planned is to swap my plastic Honda light for a beautiful chrome harley one. I also have already got the stingray skin for the katana wrap.
