Re: tires???
^^^ Maybe more turn in. I know of ppl who have gone from 190 to 180 on Gixxers 1k and the report better handling and turn in ability.
BTW, I have a dunlop Qualifier and i love it (better than the metzler i had in the rear). I've heard good things about the pilot powers too. But i think/feel like the PP are tires for more advanced riders; as far as i know, they're like race tires and shit. I think it would take a advanced rider (cojones) to actually USE, and take advantage of them. My dunlop has been very faithful to me so far.
