Casey Stoner took his third pole position of the season in Valencia today using the harder of the available front slick tyres and the softer rear Bridgestone. There was a strong wind again today which made it very difficult for the riders, especially as the wind carried dust onto the circuit.
This resulted in front tyre choices throughout the field being divided half and half between the soft and the medium compounds. Of the top six, third-placed Jorge Lorenzo was the only rider to choose the softer option front slick, the rest using the harder variant to set their best time.
Dani Pedrosa was second fastest using a harder front and softer rear slick, Lorenzo was third on the softer option tyres both front and rear, and Valentino Rossi was fourth on the hard front and soft rear. The top three all lapped faster than the existing circuit lap record, set by Stoner on a Bridgestone-shod Ducati last season.

"During qualifying the front tyre choice was split throughout the field which again shows the overlap between the operating ranges of the soft and medium front tyre compounds. I think that the reason for the split choices came down to what each rider felt more comfortable with as a part of the whole bike, rider and tyre package in the dusty and windy conditions which made it very tricky.
"In the morning's practice and during qualifying it was very windy, and the wind affects the bikes a lot here so it was difficult to set a good laptime. The dusty track also meant that achieving good edge grip from the tyres was tricky, especially at this twisty circuit. Nevertheless, the top three went faster than the existing lap record, set by Casey last year on our tyres, so I am pleased with this as it shows that both compounds of our slick tyre are performing well even in these conditions. If the weather tomorrow is similar, I expect riders' front tyre choices to be divided again, but the hard compound asymmetric slick to be preferable for the rear."
