Casey Stoner experienced no recurrence of the back pain that threatened his third place finish in Sunday's Portuguese MotoGP, during Monday's test session at Estoril.
“The beginning of the day my back was really sore and difficult to ride with but then it eased a little as the day progressed, so I hope it continues to get better,” said the Repsol Honda rider.
Stoner was also third at the end of the test session, with a best lap time 0.391sec behind Gresini Honda's Marco Simoncelli.
The Qatar Grand Prix winner focused on the latest Ohlins front fork, but also tested clutch modifications and the 2012 Bridgestone tyres.
"We haven't had a lot to test, there aren't really any new parts, we tried a different system on the clutch which was fine but not actually improving on what we have,” said Stoner.
“We tried a few Bridgestone tyres with a new construction and compound, they were definitely an improvement especially on the left side, so that went well.
“We tested the new 2011 fork and everything worked well with them, last time we tried them we had some issues with chattering but we seem to have fixed that now.
“This is a big improvement as these forks work better on the bumps and on the brakes so hopefully we can continue to use them in the future.”
Stoner heads to round four in France holding third in the championship, 20 points behind team-mate Dani Pedrosa and 24 from Yamaha's reigning world champion Jorge Lorenzo.
