Suzuki looking into MotoGP electronics gremlin from Mugello

One of the Italian Grand Prix pacesetters, Vinales equalled his best qualifying result with second on Saturday, just 0.094 seconds behind his future Yamaha team-mate Valentino Rossi.

However, after getting a decent launch, Vinales' GSX-RR lost pace momentarily on the run to the first corner and he fell to 11th, eventually recovering to sixth.

"I'm very disappointed with the race, we did really well the whole weekend and finally we couldn't get the deserved result," he said.

"I really had the feeling we could fight for the podium; both in practice and in warm-up I felt very comfortable and confident for a good race.

"Unfortunately, all the problems came from the start: I had a good jump, but then when it came to put it into fourth-gear something went wrong with the bike's acceleration and this made me lose so many positions.

"Then the problem disappeared and everything was working fine for the rest of the race.

"But because I was behind so many riders, and I had to push very hard to recover, this destroyed the tyres, which were finally too-worn to get closer."

Vinales believes much more was on the cards for the improving Suzuki, which will conduct a private test at Valencia before the next round at Barcelona on June 3-5.

"It's a shame because according to the timesheets my pace was as good as the leaders," the 21-year-old added.

"So this meant that with a good start I could have fought for the podium, which I felt was achievable for us.

"It's a pity, but now I need to revise the data with my engineers and understand what happened in order to fix it."
