Portugal Colonial - Tearful Aleix Espargaro wins first MotoGP race at 200th attempt

The 32-year-old also gave Aprilia a maiden triumph in the sport's premier class while he took over the lead of the world championship after three rounds.

Jorge Martin, on a Ducati-Pramac, and Suzuki's Alex Rins made it an all-Spanish podium.

"I am really happy, I have waited a very long time," said a tearful Esparago who joined Aprilia in 2017.

"It's particularly special as it was my 200th race in MotoGP."

In all, Espargaro has taken part in 283 grand prix across the sport's three classes since his 2004 debut in the now defunct 125cc class.

"Everything was in place, we were solid on the pace, but it was double pressure because everyone was telling me it was going to be easy, but it wasn't.

"The last laps were my strongest. I thank everyone at Aprilia, I think we really deserve it, and the other incredible thing is that we are leading the championship.

"Six years ago, nobody believed in Aprilia."

Espargaro started from pole, his first since his Suzuki days seven years ago at the Catalunya Grand Prix in Barcelona, but Martin immediately roared past.

The 24-year-old Martin, chasing his second MotoGP win after the 2021 Styrian Grand Prix, held off his compatriot for large parts of the 25-lap race.

Espargaro twice nipped past, only to run wide. However, it turned out to be third time lucky when he made another daring overtake finally stick on the 18th lap, holding the lead comfortably to the flag.
