UK Jase, I wouldn't do it. Like someone else said, it will screw with the profile of the tire unless you get a wider rim, and it will compromise the handling. I think the stock F2 rims are 4.5" and designed for a 160. I think an F3 rim might work ok, tho, because they are 5" rim (even tho the stock size is 160 also).


You definitely need to chill out, man. (And stop putting 210's on F4s...)
It's just not cool.

 

i have a 03 f4i how wide could ya go???? 200? or 190??

 

I would say max 190 but i hear you can go wider... i wouldnt do more tho but thats just me

 

Wider tires make our bikes ride worse... I can understand OP trying to keep his cheap source of tires working for him but the rest of you going on about 190s and 210s... oy.

Spending more, for more rubber, of which you actually will use less. Let's think this one through, eh? lol

 

sorry for the wrong info. i checked my tire. its a 210d series dunlop tire the actual tire size is 190. so i guesse i am a full of chit knuckle head. would rather admit to being wrong than give wrongful info. thanks christopher...good luck with your build. look forward to pics..

 

Thanks to all who replied and to those who went bonkers over a tyre!!

I've now fitted a 180 after talking to several "CBR steely" Auto66 Club racers who use a 180. They say it does tip in a bit quicker but as I'm a noob I wont notice it (thanks chaps). Bike looks mega with a 180 on it and I'm at my first trackday at Cadwell Park in the UK Friday next week. Need the sun....

thanks all

so you did get the 180 on the stock f2 rim? would love to see some pics!

 

Hi all

See below and/or my album. Been out today and feels fine. New fully race scrubbed rubber front and rear so feels a bit strange at mo but track day will sort that out. Felt very nice and turned in well once tyre up to temp - hope you like my ride

 

what size is that exactly 180/ / and what size front do you run also?

 

Running Metzeler K2 Racetec 180/55/17 on rear and 120/70/17 Pirelli Supercorsa on front
