Im 6'5 230 lbs. I rode a 99 VFR800 for 2 years before I bought my 1098, and since i bought the bike without riding it before, I was a little scared that I wouldnt fit righ and would have to suffer on it, which is really something i was willing to do. To my great relief, i noticed that I actually feel better on the 1098 than the VFR. My knees go exactly where they belong, my feet are just enough back, and my reach is just right so i can keep my elbows bent without leaning forward too far. Ive ridden the bike 2 hours 106 miles to my vacation house, and I actually felt better than i did when i rode the VFR there.
The europeans just obsess over ergonomics. I sat on a CBR1000RR yesterday, and i got a cramp just being in the showroom.
So in reality, youve been riding cramped bikes for 20 years, and youll get used to the more natural position of the 1098.
