Yamada reflects on Jerez performance and front qualifying changes

Yamada reflects on Jerez performance and front qualifying changes

Although Bridgestone's four-race run of MotoGP victories came to an end at Jerez, the extremely quick times in both the race and qualifying mean that the manufacturer cannot be too disheartened by their riders' performance.

Although Bridgestone's four-race run of MotoGP victories came to an end at Jerez, the extremely quick times in both the race and qualifying mean that the manufacturer cannot be too disheartened by their riders' performance. Hiroshi Yamada from Bridgestone analysed the weekend and two days of post-race testing in his traditional debrief.

"In terms of the performance of our tyres, I think we can be very pleased, even if the end results from the weekend are somewhat disappointing. After the three free practice sessions over Friday and Saturday morning, we had five of our riders in the top seven of the combined standings and the tyres had shown good consistency over many laps."

"Qualifying was incredibly competitive and we only missed out on pole by just over a tenth-of-a-second, but that time, set by Casey Stoner, was only good enough for fifth place. In the race itself, our tyres were quick and consistent over the full 27 laps of the race and in the closing stages Toni and Casey were lapping over half-a-second quicker than everyone else. Although we missed out on the podium, we derived great satisfaction from the level of performance from our tyres in the race."

On the changeable track conditions, owing to a rise and drop in temperatures, Yamada added: "We enjoyed a dry weekend, but the track and ambient temperatures fluctuated a lot over the weekend. The track was as cool as 15°C on Friday morning, but as high as 40°C during qualifying. We provided our teams with medium and soft compound tyres in Jerez, both of which had performed well during practice sessions."

"The slightly cloudier, cooler temperatures we experienced on Sunday allowed us to run the softer specification of tyre which was still giving optimum grip on the final lap of the race. Toni Elias posted his quickest lap of the race on the third lap, 1m41.395s, and set a 1m41.916 on the penultimate lap of the race, just half-a-second slower. Casey Stoner's best of 1m41.443s came on lap seven, but his final lap of the race was under four-tenths slower, 1m41.825s."

"The weather even played a role after the race because the post race test with all five of our teams on Monday was hit by rain. We used the opportunity to evaluate the latest generation of Bridgestone wet weather tyres, since many of our teams have not had the chance to run their new 800cc machines in wet conditions."

"Although Tuesday's weather was better, the rain-interrupted day on Monday meant that we did not have sufficient time to carry out much of our test programme. Concerning qualifying tyres, we were able to try one specification front and rear qualifying tyre. We worked with Honda Gresini, Kawasaki and Ducati on this second day and we saw some interesting lap times. Marco Melandri was quickest with a time of 1m39.484s which was 0.082s from Dani Pedrosa's pole time on Saturday afternoon."

The proposed front qualifying tyre change has not yet been introduced, and is unlikely to make an appearance until after next month's race in Turkey.

"We hope that our front qualifying tyre development work will prove advantageous in the long-run, but we still need more time to evaluate the front spec, so it will not be introduced in Turkey. I believe that the rear tyre is where we will derive most benefit and improvement in qualifying performance. The initial test results from Tuesday were certainly promising and we are quite pleased with the progress made so far."
