Dani Pedrosa has topped the timesheets during Friday’s practice sessions at Sepang, almost breaking the lap record at the Malaysian track.
Pedrosa posted a time of two minutes and 00.554 seconds, narrowly missing out on beating Jorge Lorenzo’s record, to make a strong start to his weekend despite the injury problems caused in Aragon.
"Today went well,” said the Spaniard on the Moto GP official website. “We had two good practice sessions and were able to ride in dry conditions in both the morning and afternoon.
"In the second session it looked like the track was going to be wet after a brief rain shower in-between FP1 and FP2, but it dried out quickly and we were able to continue working on our setups.
“When sitting on the bike I have quite a lot of pain, as the seat is very hard, so we shall see if a few more anti-inflammatories can help to alleviate the issue.
“We might also add a small cushion underneath my leathers, in order to absorb the bumps that we get when riding."
Championship leader Marc Marquez was second fastest, coming in half a second behind his Repsol Honda team-mate, and looked sharp on track.
Briton Cal Crutchlow posted an impressive third, which might signal a return to form for the Tech 3 rider after a series of disappointing displays.
Valentino Rossi was fourth, ahead of his Yamaha team-mate Lorenzo, who was unimpressed with his bike’s efforts on Friday morning.
"We cannot control the performance of the other riders - we can just improve ourselves," the world champion told BBC Sport.
"I have to be confident. It's the only way. If you don't feel confident or you are unhappy, it's the start of the finish."
