jk750 pretty much answered your question.
I can tell you from personal experience that the F4i handles both street and track duty equally well.Truly one of the last and perhaps the best do-it-all machines ever built. RIP (not being built for '07). I think the 'Zooks are definitely more track oriented (obviously) so you have to take that into account on your decision. My friends that I ride with (mostly CBRs) keep telling me to get rid of my "dinosaur" and by a new 600RR but I wouldn't get rid of that bike for anything! I love it and it does everything that I need it to do.
Hope the info helps!
