Bridgestone has rejected claims that a rear tyre problem was the cause of Jorge Lorenzo's miserable Le Mans performance.
The reigning double MotoGP champion slumped from second to ninth in the wet race, eventually finishing seventh after accidents for Valentino Rossi and Stefan Bradl.
Afterwards, Lorenzo spoke of a chronic lack of rear grip, saying ”I don't see anything other than the tyre causing the problem"
- a theory Bridgestone Motorsport Tyre Development manager Shinji Aoki does not agree with.
“It was clear during the race that Jorge had an issue as he couldn't keep the same pace as the leading group. Immediately after the race he had a debrief session with his tyre engineer where he explained his lack of rear grip,” explained Aoki.
“As is always the case in these situations, his engineer thoroughly examined Jorge's race tyres which were found to be in good working condition. In addition, I examined the tyre myself and personally discussed the matter with the Yamaha engineers and we all agreed that Jorge's lack of rear grip was not attributable to his tyre.
“We received many different comments from the riders after the race on the feeling on the track, even though they all used the same specification of wet tyre and endured the same track conditions.
“In these low grip situations, machine set up is critical as the smallest setting change can have a big effect on performance.
“In any case it was a shame for Jorge as he was so strong in morning warm-up and we all expected a better result from him, but he is a champion and I know he will be back to his competitive best at the next race.”
Lorenzo, the top Yamaha rider, is now third in the standings behind Repsol Honda riders Dani Pedrosa and Marc Marquez.
