Both riders had a new evolution of the 2010 prototype YZR-M1 to try alongside a 2009 bike, a step on from the first version they tried in August in Brno. They both reported back positively to the Yamaha engineers and were able to set some good times on the prototype bikes. Lorenzo`s best time was just 0.025 seconds off Stoner, with Rossi 0.141 seconds behind his team-mate.

"I was really excited to try this new version of the M1 today and I had a lot of motivation to get back to work. The feeling out of the corner is much better and we have more grip already in the rear so it`s a big improvement for me. We still need to work on accelleration but I like what we have so far and I think we will continue to be competitive like this year. We have to wait and see the comparison between the old and new bike at a different track next year, but I am excited. I`m quite tired because this is already our fourth day riding here, but I am happy to have one more day of testing."
