does anyone know the exact size of the the stock F2 rim width...i thought it was like 4.75" but my pops measured 5.5" when he was balancing my rim anyone have any input??? if all this is right ill slap some 180s on there and get the 520 conversion

 

I know my 98 f3 has a 5.0" rear wheel and I believe that older f2's had a 4.5" rear. F4i's have 5.5" rear.

 

never mind, i forget.

 

LOL yeah i knew 4.5 wasn't right. Here this is from cbrworld.net

You will notice below the 91-94 has a 4.50 rear and the 95-98 has a 5.00, then 99 is 5.50.
even tho it say the 5.0 take a 160 look at it this way. 4.50 takes a 160....5.50 takes a 180, I put on a 170 on the 5.0....and also if I wanted to go back to 160 I still can....

yeah that's sounds good lol nice research!

 

fyi, a 180 will fit but the wheel will pinch the tire, thus making it taller than its supposed to be, thus effecting handling.... a 170 is ideal

 

Ditto what he said about the 180. I tried one on an f3 rim and had about half a milimeter of clearance to the swingarm. If you really want a wider contact patch, get an f3 rim. The extra half inch of width makes a noticeable difference when your running low pressure. Also, buy a tire with a touring profile.
