We had a debate on a blade forum a while back about tyres and manufacturers, and most agreed that, as Paul has just said, mots modern day tyres are good. It was also thought that using sport touring tyres was better than sport, as they warm up quicker, and usualy give better grip in the wet. When I think back, even 10 yrs ago, tyres were harder, lasted much longer, and I still had the bike well banked over. We listen too much to the journo's in bike mags these days, and its only their "opinion" about each brand.
A pal of mine has has pilot road 2's on his 08 busa and throws that about with gay abandon - no chicken strips. He got 4500 out of the rear, which I think is quite good for the way he rides.
Bloody hell, I've rambled on here, must have a temperature.
