I rode the F6 from Harley and loved it. A pain in the ass to repaint, and work on but that's the deal with a wing as well.
After changing the seat as Dave mentioned, repainting and installing cruise I was pretty happy with the F6. Then my grandson decided he wanted to start riding and I just feel much better with the tour pack behind him on a full wing rather than the back rest of the F6. Besides I love the color scheme on the new wing. I took most of the goodies off of the F6 and put on the wing. As Dave mentioned the first thing was to order an Ultimate seat and get rid of the stock one. As far as performance there really is not much difference. I kept the dark side tire and will put it on the wing. The biggest thing I noticed was how smooth the transmission shifts on the wing. My F6 was clunky, and shifted no where near as good as the new wing. I like the additional goodies on the wing. Reverse is no big deal for me.
But oddly enough, the foot heater vents I have found to work really well when riding to work this winter. Ok I admit it, I am spoiled. I went from Harleys and choppers, with no wind shield to a full wing. Over the years I find the older I get comfort becomes more and more important. Yup the "cool factor" is gone. But I still aint stopping at the Dairy Queen on the wing.
