Is it possible to run a 170/60/17* for the rear on our F2s? I can score one for VERY cheap.

 

If you mean 170/60-17, yeah it's possible. You'll never fit a 170/60-16 on that rim, and I'm not sure anyone makes that size. I had a 170/60-17 on mine when I got it with a 120/70-17 up front and it turned in like crap. Going to stock made it way more nimble. It may just be because my front end is way lowered and that ruined the geometry of the bike, but I didn't like the 170/60 in the back. Just my $0.02.

 

i have a 180/55/17 on the back of mine and I can still burn most of my buddies through the neighborhoods. If you can ride it won't make to much difference.

 

Yeah I meant 17. 170/60-17.
