MotoGP teams were back in action on Monday as they underwent the official IRTA test on the Jerez de la Frontera circuit in Spain, home to Sunday's fourth round of the 2017 championship and by the time the session came to a close it was Maverick Vinales at the top of the timeseheets. The Yamaha rider completed a total of 84 laps, his best time of 1:38.635 recorded on his 23rd lap around the Spanish venue. Meanwhile, teammate Valentino Rossi, completed 62 laps and was classified 21st.

“It was important to have the possibility to stay here for some testing after yesterday‘s race,” said Yamaha Racing's Massimo Meregalli. “We had the opportunity to test an updated frame with both riders as well as the new front tyre that Michelin brought. The new frame had some positive points, though there are some areas that we can still improve.”

“While Valentino was working on different bike set-ups, Maverick went out on a bike with the same set-up and tyres, when the temperature was exactly the same as yesterday during the race. He did half a race simulation and the pace was faster than yesterday. During these laps, the feeling of the bike was that it worked as we expected it to work during the race. We will now analyse all the data that we collected today and yesterday to try to understand what the culprit was. We are looking forward to making another step in Le Mans in two weeks‘ time!

Marc Marquez was second fastest overall, a mere 2 thousandths of a second behind Vinales with teammate Dani Pedrosa was close behind in third.

The two Ducati riders, Andrea Dovizioso and Jorge Lorenzo, finished fifth and sixth while Andrea Iannone was the quicker of the two Suzuki racers down in 13th place.

“We did a very intense day of work today, both Andrea and Tsuda ran more than 90 laps each which allowed us to try many things,” said Suzuki team manager Davide Brivio. “One thing was to test the Michelin front tyre, just like every other team did and we liked it. In case Michelin will decide to keep it as an option we would be positive about this. Then with Andrea we wanted to take a breath in a more calm situation as a test is to explore all the possibilities we have with the setting and balancing, and we managed to make a positive work.”

“We collected much information, we could make many back-to-back tests and compare different configurations. The same we did with the electronics, we saw some small improvements. Tomorrow we will continue this work trying to check some more ideas we still have and finally put everything together to create an effective package for Le Mans. “

“Also with Sylvain we started the preparation for the race, today he could run 37 laps as a first touch of our GSX-RR and the Michelin tyres, there are so many new things he has to adapt to. Tomorrow he will stay with us and he will have available for him the whole crew, since the mechanics today had to split between Sylvain and Tsuda. It's going be a full day for him, but he's getting back to MotoGP in his home grand prix so I'm sure that he is eager to get as ready as he can just as much as we are to put him in the best conditions for a positive race.”
