Following Sunday's Czech Republic Grand Prix a test session was held back at Brno on Monday.
The test ended earlier than planned due to rain.
All of Sunday's race riders except Randy de Puniet (LCR Honda) and Alex de Angelis (Interwetten Honda) were back on track for the test, which also saw Hiroshi Aoyama complete his first MotoGP laps since fracturing a vertebra at Silverstone in June.
Former MotoGP rider Sylvain Guintoli returned to the paddock to take over from Rizla Suzuki rookie Alvaro Bautista, who injured his back on Saturday.
MotoGP title leader Jorge Lorenzo and assumed 2011 team-mate Ben Spies both tried an early version of next year's Yamaha YZR-M1, while Honda, Ducati and Suzuki also brought new parts to try for this season and next.
Dani Pedrosa rode a Honda test bike as well as his usual RCV. Each bike was fitted with a transponder so the Spaniard is listed below with his best time on each bike. Pedrosa was unhurt in a fall from his usual 2010 bike.
The next chance for MotoGP testing will be immediately after the Valencia season finale, in November.
