Joan Mir struggled to take in what he had achieved after being crowned MotoGP™ champion for the first time at the Valencia Grand Prix.
Just a week after clinching his first win in the premier class at the same track, a seventh-place finish at Circuit Ricardo Tormo on Sunday was enough for Mir to wrap up the title.
He is Suzuki's first world champion in the MotoGP™ era, while their previous winner in the premier class was Kenny Roberts Jr in 2000.
Asked how he felt after making his way back to the garage to celebrate, Mir said: "Unbelievable. I don't have words to describe this emotion because it's something I've been fighting for all my life.
"At the moment I can't laugh, I can't cry – it's a mix of emotions. I'm really, really, really happy, because you follow one dream all your life and you finally achieve it.
"I don't believe what's happening. I need time to relax and understand what's happened because I don't have words."
Suzuki team manager Davide Brivio added: "What Joan has achieved is incredible. He is a great rider and has given Suzuki a world title after 20 years, something for which we are all very grateful."
In his second season in the premier class, Mir is the third Spaniard to win the MotoGP™ title after Jorge Lorenzo and Marc Marquez.
Marquez surrendered his crown having missed all but one of the races this season with an arm injury.
