A second day of post-race testing at Le Mans concluded early when the Ducati Corse engineers, studying the data in their possession, singled out the component that caused the breakdown of Casey Stoner's engine in the Grand Prix de France. It was therefore decided not to continue with the test in the afternoon in order to avoid further damage to other engines. Engineers back at the Borgo Panigale factory will now replace the component in question before the team's home race at Mugello in just over a week's time.

However, sunshine yesterday and today had allowed Stoner to complete the majority of work planned for this test and the Australian was straight back on the pace this morning on race tyres.

Marco Melandri completed only a handful of laps today. With lower ambient and track temperatures he waited until 10:30 before taking to the track, and then he also stop at the lunchtime break, at 12:00.
