Just playing around with the idea of it. I am the type person that likes something different pretty often. Obviously I don't really have to get a different bike, but change can be fun. I do 90% of my riding at Deal's Gap or the surrounding curvy roads. No long trips at all and my commute is 1 mile to campus. I am thinking that the r6/600rr might offer a little better handling for my type of riding. Love my f4i though, can't complain about it. I feel that I am experienced enough to move up to a liter bike, but honestly, for the type riding I do I don't think I should.
