aren't good in the wet the wet though, mate has them on his gixxer 750!!!
if you want maximum grip go for the metzeler racetecs, K2 preferrably, its the dogs bollocks when it comes to dry grip, i could open the throttle completely in gear 2 mid corner and it would not even twitch. thats no exageration. they are **** in the wet though and mine lasted about 600 miles! about £300 per set and all, so expensive but grip costs dollar!
i run a 120/70 and a 190/55 and have no issues whatsoever. i have an R though so it has a wider rear (i think???) but no rubbing or anything like that. the taller tyre tends to fall into corners better, which i like!
anyway new tyre bedded in and running sweet. grips very well although haven't tried gear 2 mid corner yet!!! if i write it off you'll be the first to know. you'll hear me crying for miles away.
