ok...ive tryed heaps of tyres and rate the sports high.....compared to the 207 eg (stock fittment on old 12s) they have more grip when cold, and more gripo when hot though i found them a little unpredictable on the limit they would step out in a hurry..where the 207s had less grip...but easier 2 slide....but ive been running pilot sports ever since...getting the powers soon....if u want all out grip go for the pilot race h2 simply awesome but they wont last long and cost a fortune...the pilot hpx was specifically designed for use on the 12..i was getting 4000kms hard riding out of one..on the road
