Czech Republic MotoGP winner Dani Pedrosa spent Monday's Brno test session working on various areas of his Repsol Honda, including chatter issues and a new rear shock.

Sharing the pits with Jonathan Rea for the first time, Pedrosa rode for 45 laps, the best of which put him fourth on the timesheets, just 0.242s behind Tech 3 Yamaha's Cal Crutchlow.

"Today, we've done a general test looking to improve the feelings we had in yesterday's race," said Pedrosa, who snatched victory from Jorge Lorenzo at the very final turn of Sunday's race.

"We tried some ideas to reduce the chatter, but this is something very difficult to fix, so we've been basically working on the electronics and the suspension trying to find more edge grip and in the exit of the corner.

"I tried a new ?hlins shock which gave me some positive feelings and now we have some new ideas to try in Arag?n next week.

"The track was a little bit slower than yesterday and in the afternoon it was quite windy, but this test was important as it's a good track to test at and I had all the references still fresh from yesterday's race."

Pedrosa is now just 13-points from Yamaha's title leader Lorenzo, who was third quickest at the test.

Repsol Honda will resume their test schedule in Aragon on the 4th and 5th of September, prior to the Misano round in mid-September.
