Sylvain Guintoli has joined Suzuki team-mate Leon Haslam in claiming the new evolution Pirelli tyres are not as effective as their predecessors, despite him scoring his some of his best results of the season at Brno.
While Haslam has signalled his displeasure with the revised rubber, which he claims has contributed to his disappointing run of recent form, Guintoli has enjoyed an upturn in results, finishing inside the top seven in each of the last four races.
Indeed, the Frenchman's fourth best place finish in race one at Brno equals his previous WSBK best, while it also extends his perfect scoring record so far this season.
Even so, Guintoli admits the new tyres are proving inconsistent on the Suzuki, claiming they 'behaved very differently' between races one and two.
“I am quite happy with my results, especially my fourth in the first race. I felt good and I enjoyed the first race more than the second.
“Just like Misano, we have been struggling getting our bike to work with these new tyres. We've been having problems setting up the bike with these tyres, but when we use the older tyres we have much less problems. I used the new tyres in both races today, but the one in race two behaved very differently to the one in race one, even though it was the same type!
“After my fourth in race one, I was looking forward to giving it a real go in race two, so it was a bit disappointing that the tyre didn't grip. It meant that I just couldn't push as hard as I wanted to and I struggled throughout the race.”
Guintoli remains 11th in the standings, but is now equal on points with ninth place Leon Camier and tenth place Cal Crutchlow.
