That thread is about Pilot Power 2CTs, not PR3s.
There was a thread that initially bothered me a little bit last year on the same forum I think. A guy with one of the FZ bikes had a problem with the rear, and then blew the front and ended up crashing into his wife's SUV and going through the back windshield.
There were some things about that thread, and some things he said that made me question his story. The more he yapped, the more full of it he seemed. Anyway...I ended up buying a set and have a couple thousand on them. No problems yet. They run smooth, hold their air, stick well, no rubber has peeled off, and they seem to be wearing fine.
Maybe if I have them in the heat of the summer, things could change, but it strikes me funny that only guys on FZ6s seem to be having issues.
