Could you tell me the riding position/ posture of the F3 compared to the F4? I see that you mentioned the seating position and compared it to the F4. I haven't been able to sit on the F3 but have sat on the F4. I'm a small guy, 5' 7", and the sitting position is a little extreme for me on the F4. I've heard the F3 positioning is not as extreme as the F4 but not as comfortable as the CBR600RR...somewhere in between.
I'm contemplating it because I have a 2010 F4 for sale near me for that same price as the F3 would cost and trying to decide between getting the F4 or wait for the F3.
Your feedback would be appreciated since I take it that you had a chance to experience both models.
