theres a test in ride this month regards sports tyres v sport touring tyres,
guess which came out best?
yup,the tourer,upto temp much much quicker,held its temp much longer and kept in the optimum temp range all the time and good for at least double the mileage!!
that was a dunlop v the qualifier rr.
there was in the same mag,a man who swore by his pirelli diablo rossos,so they did a blind test,with 5 tyres,so the man didnt know what he was using each time,and his own pirelli....he rated the worst,hated them.
on blind riding,he loved the avons or bridgestone for feedback,confidence,composure over bumps,turn in speed and feel,being able to ge on the gas early out of corners ect.
