Pirelli Supercorsa's for me. I'm partisan as I just love these tyres. The last tyre I felt this good about were the 207RR's. Once I find a tyre that feels right for me, I stick with it. Plus, I like the pattern. I really am that shallow.
Got Bridgestones on my bikes. I'm the same with sticking with what I know and like. The t30 evos I have on my 748 and had on my 749 are fantastic. But everyone rides different. Different heights, weight, speeds, roads and style. There probably isn' a truly shit tire made by any of the top manufacturers is there? Just a mater of finding one the suits you. Lil hard unless you have a big budget I guess!
