ok sorry. here are some more information and pic.
the bike is 675R. set up is the recomentaion from triumph for race minus 2 clicks from all.
tire pressure 21 psi cold.
this is a gp racer endurance 190/55 made in france.
the track is new and lockated in Cyprus. As i said is 2 km long with low average speed 95km/h. it has long slow (70km/h) corners. it is not that abrasive. there isnt a lot of camper on the corners.
the tire shown is after 25 laps.
I am running with the fasted.
a TT racer which was on the track was 3,5 seconds faster than me with his cbr1000.
The tire in the pic is half warn.
A friend with a cbr1000 the same day running, the same lap times, the same tire, with a bit higher pressures 25psi cold he finished it in less than 30 laps. His tire looked just like mine shown in the pic.
I would like to note that before the gp racer i had the sportsmart 180/55 24 psi. I have done over 90 laps in three days. It is still new and it does not have the wear patern shown in the pic and i was running the same lap times.
please help.
