:lol: My brother bought a GPZ600R from a friend of mine, who had just fitted A49/M48 rubber (rubbish?) on it before the sale. He did it on my advice :err: Well, my brother took the bike for a fang in the mountains and found himself sliding around most bends, often at high speeds. He was, as mentioned, not the least impressed. Then, entering the motorway, he simply fell down. No drama, no sense of slipping before he the tyres just gave in at once and gently laid itself on the side at about 90 kph. Brother claimed it was like laying down, not falling down, so he wasn't hurt. But he replace the tyres with Avon Super Venoms the very same day and was a much happier chap for it. If the Pures were too soft, it's no wonder the 1400 didn't like them. Michelin M38 (old stuff) and Macadam bias ply also had way soft constructions and made bikes feel insecure - especially the 330 kg Z1300!
