Tony, didn't really find out why it was like this, can only presume i was just giving it a bit much in the bends, haven't noticed it since on Distanzia's.

Cbr-ica, heavy ??? me???? its all muscle honest.

Maxwell, it wasn't that hot as you say maybe too much stick

... and tyre pressure?

My tyre did exactly the same, maybe it was slightly more worn than yours, but after a 50k ride home i noticed the rubber on the edge. Then i noticed the cord showing through in one tiny place. i suspect the compound was overheating due to lack of tread and the rubber started moving around.

I fitted a rear distanzia next day......
