I'm currently riding an '98 F3 which is pretty awesome, but want to upgrade to a newer F4I soon.
The F3 maneuvers sooo nicely, it practically does U-turns by itself.
Can anyone tell me if the F4I is just as sharp or sharper?
Thanks!

 

i have'nt ridden an F3 but my F4i handles awsome ..its so light , effortless to toss it around, very nimble

 

F3's are great bikes. My friend use to have one. I thought it handled the road very well. On a highway, because f3 is heavier it sticks to tha pavement better. As far as turning and turning radius I beleive they are the same. Something like that is hard to judge because you need to compare the two bike in the same vacinity and I havent done that.

 

Thanks for the inputs. They seem very similar and most likely just get better all around as the new models develop.
I do however like the f4I 2001-2003 because of the racer style seats, although I'm sure they can get uncomfortable at times.
