Maverick Viñales kicked off the 2017 MotoGP pre-season testing in Valencia on a positive note, finishing first in today's session timesheets, 0.020s ahead of Valentino Rossi in second place.

Though the main goal of today's outing for Viñales was to get a feel for his new bike, he didn't waste time to make a statement. The Spaniard started his test around eleven o'clock and only took half an hour to ride to second place and continued to be in the top six throughout his morning run. He kept the momentum going during his afternoon stint and showed his confidence posting a 1'30.930s on lap 55 to take over first place from Rossi. The 21-year-old completed 61 laps in total and wrapped up the day of testing leading the way.

Rossi had a mixed but ultimately successful day of testing. He was quickly on the pace in the morning on his 2016 bike and topped the standings after his 11th lap, clocking a 1'30.950s, which was only bettered by Viñales later in the afternoon when the temperatures rose. Despite suffering a crash on lap 32 in turn 10, he walked away unharmed and started the Valencia test with a positive feeling overall. The Italian spent his afternoon session preparing for next year's season. He completed 47 laps in total and finished in second place in today's testing results, just 0.020s off the front.

On Wednesday,  Movistar Yamaha MotoGP will be back at the Ricardo Tormo track to continue their testing programme.

"Today has been a momentous occasion and a promising start to the first pre-season MotoGP IRTA test. Maverick made his first kilometres on the Yamaha and, just like we expected, he has taken to the bike very well. He used today just to get a feel for the YZR-M1. Valentino was very quick this morning on his 2016 bike. It was unfortunate that his crash on the bike with the 2017 frame lost us some time, because the damage was quite substantial, but the main thing is that Vale is OK. Later in the afternoon he resumed his testing plan and the feedback we got from him is very clear, so overall we are satisfied with how the test has started and with our progress so far."

Valentino Rossi - 2nd, 1'30.950, 11/47 laps

"It was a positive day, because I'm second and the lap time was not so bad, but I did it with the old bike. With the new chassis the first feeling was OK, but after unfortunately I crashed because I put the hard tyre on the front, which on the right side doesn't give enough grip for our bike. I damaged the bike and I didn't have enough time to try it again, so now the guys are working and I will try the new chassis some other time tomorrow and we will see."
