I run Dunlop 952's and usually run the 120's, but I got a 110 on at the moment and I don't know if I like it or not. One thing I cam tell is that there seems to be a lot more spinning, slipping and sliding going on now compared to the 120's. The 110 seems a lot more rounder too, which wouldn't help. I think I will be sticking to the 120's. I think on a stock(ish) bike, there wouldn't be too much of a problem running a 110 though, and would benefit from the smaller size. I just think it would be interesting to hear some other views.
