2:00m flat is my best so far at MSRH(cw), I think.

But to give myself a little credit, I'm new to the track scene......so.....I'm working on getting faster.

But most of the time, good lap times mean the tires are getting pushed hard enough to booger up I guess.:/: So, i guess your right in a way.....but that's not always the case.

not necessarily good lap times. my friend's first trackday on street tires had lil boogers everywhere also...and he has only been riding for about 6 months on the street, and not so fast on the track.

u know what those lil rubber boogers are? it's the 12th wonder of the world

By boogers do you mean the like lumps/ of rubber that attach themselves to the tyres or are you referring to the feathering and chewing that occurs on the tyre edges????????????????

I was trying to make the same point. Maybe I said it wrong.....

I was using my own slowness to prove the point.

More so what's on the outer walls of the tires, I guess.

right cause most of that other is picked up off the track when you go off line particuarly coming back into the pits/paddock.

Most tyre tearing and chewing is down to poor or compromised set up or cold tear all else being equal. Looks good but it isn't.

Meaning pressure set up, or suspension?

I'm assuming that tyre pressures are correct.
Poor suspension setup overworks the tyres in most cases so they chew.
It's not the only factor to consider but arguably the main.

Have a look at an AMA front runners tyres after a race.
Yes they'll be feathered from use and there will be some balling on the extreme edges but generally they're remarkably clean considering the extreme pace they run at and the extra horsepower to tap.
Using the right compound tyre combined with accurately setup top end suspension is the key here.
Some guys use their tyres harder than others and some bikes are more user friendly so we are generalizing.
With trackdays, look at the tyre chewing/tearing on some roadbikes compared to the same model bike fitted with well sorted after market suspension.
You can tune standard OE suspension to get the most from it and as expressed in another thread this is well worth doing and will improve tyre wear on trackdays in most instances. It will however never match quality after market suspension, like Ohlins and Penske, that is sprung and if you're really fast, valved to your specific weight. Of course that still needs to be set up which is a dark art that even MotoGP teams spend all weekend working on with the most advanced telemetry systems money can buy or not as is the case.

Hmmm.......

I assume that I'm not pushing my suspension that hard. Although I could be wrong. Maybe it's time for a set of race rubber?
