Czech GP: Michelin preview

"Our programme of development is continuous and our target is obviously to achieve ultimate performance" says Jean-Philippe Weber, Michelin's chief of motorcycle racing. "We will return to the types of construction that we used at places like Qatar and Catalunya, these are constructions that deliver a much wider working range than those which we used at Laguna Seca. So we will use the type 20of construction that has already brought us success this year, with front and rear compounds adapted to Brno.

"We tried out the new surface at Brno on 17th and 18th of june with our test riders Erwan Nigon (Honda RC212V) and William Costes (Yamaha YZR-M1). Those tests told us that the track is really aggressive on the front tyre but not so aggressive on the rear tyre, which means that the new tarmac isn't particularly aggressive but that the combination of the layout and the new tarmac does work the front very hard. Brno is a very undulating circuit and features quite a few downhill corners which have always made front tyre performance particularly important, a bit like Mugello. The different loads experienced through the uphill and downhill sections also complicate the task of rear tyre choice at Brno.

"Based on the tests we will bring some new compounds to the Brno race weekend, designed to offer the best grip and endurance. The resurfacing job seems to have been done well, but we will have to wait and see what our MotoGP riders make of it, because they'll be going even quicker. We certainly think the new surface will make the track considerably faster than it used to be becaus e the old surface was in quite a bad state. It will be the first time that MotoGP riders have used the new surface, so it will be important to have a wider range of tyres, with a bigger step from, say, tyre one to tyre five than we might have at some other tracks."
