Im at the track, did not know how well the bike or I would do, turns out we are both doing well, but I have run into a problem. My tires will be shot at the end of the day(pirelli) and the track rep is insisting tthe no longer make 190 rears and I have to get a 200-actually he is wanting me to get a superbike pro. Its my understanding they dont grip as well bu t last longer. Should I do a 180 which ive never had on this bike? Any thoughts? Im sure there is a million answers if I was at home laying in bed searching. Any good experienced ones?
