Zeb, that's why we do not need to fix those tyres on the V11.
For everybody, as far I know, I have had:
BT 020
Pilot Road
Diablo
Metzeler sport M1
The best tyre was for me the Diablo. I do not know other tyres on the line, like Conti Attack, pilot sport, BT 010/012, Avon, etc.
I am sure I will go further to diascover the best tyre for my bike.
Next will be Avon 45/46
