Yes Trinc you are right. This picture have been taken just after the track day with no street riding, only dirt in the middle in the pit (Blue line). I guess the right side of the tire (Yellow line) are ok because on that track there is alot more agressive left turn. The left side of the tire (Red line) is the section I want to get rid of... So I should try running less air in the tire and soften the rear rebound damping? How many PSI do you run your tire?
The other solution is to let go those new 600cc racerboy during the trackday...
... No way...
Kfkraenz I will probably go your way and only keep the wrapping section under the heat shield!
