No offense here, but you can't tell the way a bike rides in just 15 minutes. When I traded my F3 in and bought my 636, the 636 felt extremelly awkward. I did love the brakes which were/are perfect, the tranny, and throttle response, but the handling and seating position were so different than my F3 that I was having second thoughts. Now after about 3 weeks of riding it, I feel in love with the bike and feel like it and I go together perfectly. Just about 2 weeks ago I rode a 04 R6 and the same thing happened again-I rode it for about 15 minutes and didn't like it at all compared to my bike. The handling was soo much different, although very stable and light, but the seating, power, and overall handling was so different than what I'm used to that I didn't like it compared to my bike. But that is not a fair comparison, if I were to ride it for a week or so straight, then I would have different opinions.
