This week's Valencia test not only saw many of next year's 1000cc bikes on track, but also the official introduction of new 2012-spec tyres from Bridgestone.
All riders - whether on 1000cc or 800cc bikes - used only the 2012 tyres, designed with the aim of providing improved warm-up performance and a wider temperature operating range.
“This test was the first opportunity for us to give all the riders our finalised 2012 specification tyres so it was very important for us," said Bridgestone's Tohru Ubukata.
“Specifically, our objectives from these new tyres are to make their grip characteristics easier to manage, to improve warm-up performance and to increase their temperature operating range.
"From the data we have collected from the last two days, I am satisfied that we have met these objectives and rider feedback has been positive so I am confident for tyre performance next year."
The test included five Claiming Rule Team (CRT) bikes from BQR Inmotec, BQR FTR, Team Laglisse and the Grellini Team.
"I'm also happy with the positive feedback even from CRT teams about our new tyre and its warm-up performance," said Ubukata.
