Well Hell...
Guys - this is my two cents, just IMHO, ok?
Based on close to 30 years of riding, probably 10 years of fitting customers with rubber, and many different types of racing, conditions, terrains, and so on.
Now. Please don't go lowering your tire pressures below recommended unless a temp guage is handy. Tread squirm is a BIG cause of 'unsettled' weirdness in tire feel. Please don't run track treads on the street, unless you are 110% sure of teh conditions - even then you will be wrong. Please match compounds front and rear, until you know FOR SURE what you are getting into. Please run tires on mfg. recommended rim widths if possible.
It took me a while to read thru this thread, and I hope I don't repeat what is here, but I've gone through a lot of tires, though I usually change them out each year.
NBL y'all are going to shred more rears than I did on my RZ500, and my interest goes back to '84 when I put street tires on my '79YZ LMAO. That got me busted.
So - Metzelers are the shiznit. Period. (for me)
I ran a season of Sportsman on Pirelli Scorpions and loved it - bar-scraping stuck, decent cleaning coming out of the dirt, good street wear.
THESE have a cool feel, but break away fast, though are predictable on the street and slide.
Shinko's feel greasy when you push them, but once off they slide well and are cheap fun Friday night rears. I've put a streetbike into 2-wheel drift on Shinkos, scary shit that.
Anything Continental is going to be good for its *intended purpose* - they've been in the game too long to build crap.
Bridgestone tires scare me after I've seen a bunch chunk out a few years back, apparently better now, but bad images.
I hope my fellow 'tards don't think you will warm tires to track temps outside of Death Valley, since on a lap you cool of in the dirt section alone (hint hint) running race weight skins.
I tend to try to fit tires to the individual, not so much the bike or the brand.
I would aim, if you think this way, for 600-class intent, as the carcass of the tires meant for sport touring / adventure are really stiff and have crap feel in general - though tough commuter rubber (gravel, glass, construction, accident debris) city guys know what I mean.
LMK if any of this bothers you, please. And - there's a ton of world-class 600-class supersport rubber to choose from, and most of it will do more than you will ask of it, if it's at the right pressure, on the right rim.
