So are you saying that everything motorcycle related that's made in the USA is crap? Because this country is in pretty bad shape right now and I think it's partly because of that sort of attitude (if you're saying what I think you're saying). How many other countries have put a man on the moon?

I'd say the new US made Dunlop slicks are nothing like the Pirelli Trackday Pro. The Pirelli is designed to last a long time, to work well on stock geometry bikes, and to work well cold. The Dunlop is just a US version of the UK slick.
So here's what the tire looked like first thing in the morning:
And here's what started to happen during the second session:
It was just the right side of the tire that was tearing. Tire pressure was 21 cold, 27 hot. Tire warmers, 75 degree day, sunny, nice warm track. I tried dropping the pressure to 25 hot and I tried easing off the throttle a bit on the right-hand exits; but the tire just got worse. So then I bumped the pressure up to 29 hot and the tire started cleaning up... but the damage was done. Here's what the tire looked like after 7, 20 minute, sessions:
Notice the nasty "shelf" on the edge of the tire and the lack of a depth indicating hole. This tire is done thanks to the tearing issue. Sad, because the left side of the tire looks great as you can see in this picture:
The left side of the tire could easily go another day or two. As for performance, it was really good until the tire started getting torn up, and even then it wasn't bad. When new, the tire felt just like a UK slick, solid (no squirminess when loaded like some other slicks) and very grippy and predictable. And even with the compromised right-hand side of the tire I was still carrying some good speed through the right-hand corners (just not the exits). This was a Medium compound (all that was available at the time) so I'd like to try the Hard compound. I've never had any luck with the UK medium compounds either (tearing issues), so the hard compound may hold up better. And if I had it all to do again, I would have started the tire at 23 or 24 cold. Maybe that would have helped?
On a side note, never had a problem with any of Dunlop's front slicks. Medium (6680) compound or Hard compounds have always worked beautifully. But now we have a new UK 120/70 front Dunlop slick. That's right, no more 125/80 front slicks. I ran the new 6875 compound (same as the older 6680) at 30 psi cold, 35 hot and completely destroyed both sides of that poor tire. A fellow rider also tore the hell out of his 120/70 Dunlop front (not sure of the compound) so evidently the new 120/70 isn't as resistant to tearing as the older 125/80's were. That's no good. I could usually get 4 or 5 days out of a front. Not 1 day. Mr. Moss thought tire pressure might be the issue but I was already running it fairly high. Do I want 37 psi or higher (hot)?
So the bottom line is: Great tires (front and rear) if you can keep them from self-destructing. Your mileage may vary.
