ok,had a 250 rebel for 3 years, a 750 shadow for 2 years & now i want to try the flip side of riding. bought and sold a cbrf4i i got from a friend and made a few bucks, but I just cant shake the feeling I got from that damn thing when I took it out for a little test ride before i sold it, holy &$%# I almost lost my arms! I loved it, enough to sell the cruiser. i have been looking at the 600cc class of sport bikes and am really stuck in trying to make a decision! The gsxr seems to fit well & is pretty comfortable, the honda cbr seat sucks, but i hear the ride is made more for ridingthan racing? the kawi ninja looks and feels ok, but I hear it rides like a rock without shocks and is only for the track, and last but not least the yamaha is a good bike but the shifting is bad?. I've gotten way too many mixed signals at the dealerships I need some help from people who actually ride!
