Movistar Yamaha MotoGP‘s Valentino Rossi faced the hot and especially humid conditions on the first day of the Malaysia Motorcycle Grand Prix weekend on Friday.

With the conditions being uncertain at the start of the morning session, Rossi was one of only five riders to start FP1.

However, as he headed out on slicks with half of the circuit still presenting wet stretches, he came back in after his first lap. The Italian sat out some time in the pit box waiting for the tarmac to dry, until there were 20 minutes of the session remaining. Back on track he improved on his time consistently, before shifting his attention to working on the bike‘s set-up.

He dropped a 2'01.662s best lap to finish the first 45-minute session in 12th place, 0.991s from first.

The wet conditions really suited the Doctor in the FP2 session. He was a man on a mission from the moment he kicked his bike in gear. He soon featured at the top end of the provisional standings and was in a good place to fine-tune the base wet setting - knowing he would not be able to better his morning dry lap time in the wet.

The nine-time World Champion ended the afternoon practice session posting a 2'13.071s best time, for sixth position, with a 1.431s margin to the leading rider. Rossi‘s faster FP1 time earned him 12th place in the combined practice results.

"It was a difficult day, but this morning we were lucky because we were able to do some kilometres, some laps, on the dry. The conditions weren't fantastic, because it was a bit humid, but at the end I could push a bit and my feeling was not so bad," he said. "In the last minutes a lot of riders put in the soft rear to stay in the top-10, so I'm just 12th, but my pace was quite good."

'In the afternoon we could work on the wet, because the conditions were good, it was full wet. We improved compared to Motegi, and I'm in sixth position, but I still don't feel comfortable with the bike because we don't have enough rear grip. We need to improve if we want to be competitive in wet conditions."
