Fiat Yamaha's Valentino Rossi has said he is pleased with the new, longer-life version of his YZR-M1's engine which he will use when the rules change from the Brno round onwards.

Teams are only allowed to use five engine in the last seven races and use of any extra because of a technical failure results in a ten-point penalty.

“It was hard to test after yesterday but it was a good day and we found out some important things. We worked on electronics to try to find a better power delivery and we also checked a different version of the engine for the second half of the season," said The Doctor.

"Finally we also tried a new tyre with Bridgestone. We got good feedback and hopefully today should mean I can feel even better on my M1 than I did at the weekend, which was already pretty good! At the end we also tried to set some fast ‘qualifying’ laps and I made a good time, so we’re happy. Now I am going home to Italy to have some rest!”
