Oohhh another tyre thread!
I have had 12000 happy miles on BT020s, mainy of them wet touring miles and they coped ok on the track, especially when it was cold and wet.
But today I am fitting some Diablo Corsas- was going to get BT014s but thought hey its an Italian bike so it gets Italian tyres.
I'll let you know how I get on.
