Are you being sarcastic or are you just dumb? lol...
Liter bikes uses 180's because of the much higher HP and the rear STILL slips out. Our little F2s are what, 60hp less than the liter bikes?
I run 160's at the track and do just fine. I had a friend with a gsxr 1000 who couldnt take me in the turns.
Whatever you do don't squeeze bigger tires on smaller rims. You mess up the profile of the tire and get horrible handling. If you are horny for big tires get a bigger rim, and expect slower handling.

Peoples weight and riding style do go a long way while on a track. So a 600 and a 1K could even out. You do lose Hp with wheel momentum, but can't sacrifice the contact patch/ surface area. I would choose larger grip/contact patch if I can power threw a corner without any worry. So through logic, I am not dumb.
Check the posts disservered, CBR900rr 5.5 inch 180 rim will fit on the F2/F3 swingarm.

Everybody, but Jesse is wrong! CBR900rr 5.5inch 180 has been proven to fit! The faster you go, you will need to get more lean down on the track. So that is why you need a 180 for more lean and grip(stability) for cornering. The more you corner/ lean, the faster you can get lap time, the fatter the tire.
As far as street riding, 160 will obviously work.

You gotta realize too that some of us here are responsible riders and also care about those of you who don't have a clue. Putting a tire on a rim it is not intended for actually reduces your contact patch, and changes how the bike leans into turns, making the change more dangerous.
