I've ridden both and on the street there really is no difference. you can't ride the rr like it needs to be ridden to notice a difference. if your going to stay on the track and the track only... buy the rr but if you want something that you can put miles on and not have to spend all ur money on chyropracters and pain pills mixed with bengay buy the f4i.

Wow, The F4i Really outshined the RR. The RR took two solid wins by having a higher MPH ( 2 miles ) and stopping in a shorter distance. For haveing and extra 10 Hp you'd think it would of done a bit better. I wonder if you could put some RR breaks on the F4i? hmm....

 

i have an o2 f4i and my buddys got an 05 rr i have ridden his bike and on the highway there is now protection from the wind. i guess thats why evrytime were on the highway hes usually 7 car lengths back. lol

 

wow which year did the F4i come with a centerstand? Never knew it had one.
I agree that the power on the F4i is very smooth all the way.

 

the RR might be 5% better on the track, if that. 75% of the people who ride street and do track days couldn't extract that last 5% of performance anyway
