MotoGP points leader Valentino Rossi says he will “have to try to do better” after the opening day of practice for the German Grand Prix at Sachsenring.
The Yamaha legend struggled for overall pace in the second session on Friday, as he was trying out the asymmetric Bridgestone tyre on the unusual track, which has 10 left-hand corners.
He finished seventh fastest, and didn't improve on his morning time.
"Today wasn't so bad because we started quite strong this morning," said Rossi, who was second fastest in FP1. "In the afternoon it became a bit more difficult, because the temperature rose and that made it harder to control the bike that started sliding more.
"We worked well and were able to improve the settings. I did the best time for the last section with a tyre that had already done more than twenty laps, considering this we've made a good step forward.
"I'm happy because we start with a good setting but now we have to improve a lot of small details. My pace isn't so bad, but it's also not fantastic so we have to try to do better."
Happy with asymmetric tyre
Rossi pronounced himself pleased with the experimental laps on the asymmetric tyre which Bridgestone has brought this weekend.
"I decided to use the asymmetric tyre for the entire afternoon session and the first feeling was good," he said.
"It had good grip, both left and right, and the performance of the tyre is consistent for 25 laps."
