if that is your case i would go with the F4i......it has a sweet power band and load of fun to ride......i beat a '02 GSXR 750 with an experenced rider by about 1/2 a bike length with my '05 F4i in a 1 mile drag race....

 

Which bike is better you say?

Short answer is whichever I happen to be sitting on at the moment.
