Dani Pedrosa rode a KTM MotoGP bike for the first time since his shoulder operation in a private test this week at Mugello.
The Spaniard was in action during a two-day private test at the Italian Grand Prix venue, which was organised by Ducati and also attended by KTM, Aprilia and Yamaha.
Although Pedrosa was not part of KTM's official test programme, which was undertaken by Mika Kallio, the two-time 250cc champion was eager to assess his fitness after having been out of action since his operation on his fractured right collarbone in February.
The estimated recovery time was three months, but Pedrosa was unable to take part in the recent post-Spanish Grand Prix test at Jerez as had been originally hoped.
A KTM team source told Autosport the manufacturer hopes to have Pedrosa back in action for next month's post-race test at Barcelona.
The source said: "According to x-rays, Dani is not 100% yet, but he's very close to full recovery. He was indeed in Mugello and he got on the KTM, but it was just a few laps to test himself and see his physical condition on the bike.
"He did not ride much and he was not very fast since the conditions of the track were not good, so it was not a significant test.
"We hope to have Pedrosa 100% available to ride with the test team starting in June."
It remains possible that Pedrosa could rack up further mileage on the RC16 prior to the post-Barcelona test, which is scheduled for June 17.
