Sorry, I thought we were in the Street section, not the Track section. I didn't realize he was going to be pushing this tire on the track.

... Oh wait...


Homeslice, chill... I said "doesn't automatically mean the tire won't give as much lean angle or you'll run out of tire sooner"... In some cases it will, in some cases it won't. You guys are talking in absolutes... sorry, but that's not how it works. A 120/60/17 in one brand could have very different physical dimensions than a 120/60/17 of another brand.

Bottom line: I stand by what I said. There's no risk of physical danger in switching from one size to another. It'll likely change the feel of the bike, but that's about it. Start pushing the tire on the track and you'll likely get a change in performance characteristics, but on the street it's a non-factor.

In any case, on the street it's not a huge deal... put the tire on & tweak as needed.
