I had both and sold the F6B. I could never get comfortable on it and I really missed reverse. As far as height the F6B felt higher because the seat was so wide. On the F6b you can't adjust windshield or headlight, plus no foot warmers. Also I use the trunk a lot more than the bags plus the way you lock your helmet to the F6B is funky. I also like the rear speakers on the wing. Who wants to buy a bike you have to immediately buy a $300.00 windshield for so you won't get blown off the back?
