Valentino Rossi (Yamaha), despite having had to cut short his work yesterday because of recurring pain to his right hand, says he has been encouraged by his first test with Bridgestone tyres at Jerez.

"We still have a lot of work to do on the bike in general and with regards to adapting it to the new tyres I can reconfirm my first feeling of two days ago, which was positive. Now we have a better idea where we need to work hard in order to improve further."

Davide Brivio, Yamaha's team manager, Davide Brivio echoed Rossi's impressions and think the team had gained enough information to ready themselves for the next test in January.

"It's been a very interesting test session here in Jerez; we had the chance to meet all the Bridgestone engineers and technicians who will work with us next season." he said.
