Dani Pedrosa returned from the MotoGP summer break refreshed and recharged, helping the healing Spaniard claim a perfect 1-1 in Friday's pair of practice sessions at Brno in the Czech Republic.
The 2010 title runner-up, who missed three races this year due to further collarbone fractures, put himself on target for his third win of the season by lapping under the official lap record and 0.377sec ahead of team-mate and title leader Casey Stoner.
"The feeling was very good today from the beginning," said Pedrosa. "The bike was working well from the first round and we could move ahead, improving little by little in both practice sessions.
"I think the main difference I felt is that I'm fresh after the summer break, the rest I had has helped me a lot, I can feel the energy I didn't have in the races before the break, so I hope I can keep the pace for Saturday and Sunday and be strong for the race.
"I'm very happy with the job we did in both sessions and I think we can still improve and be ready for both the qualifying practice and the race. I guess the other rivals will also do the same, so we have to keep focused.
"Today I rode alone all the time, maybe tomorrow I can compare a little with other riders to see where are they stronger or weaker than me".
