The 2021 world champion has scored just two podiums this season as Yamaha languishes joint-last in the standings with Japanese rival Honda.
Quartararo has made no secret of his frustrations throughout the year, and has repeatedly told Yamaha he wants to see actions to his problems with the bike and not just words.
Both Quartararo and Marc Marquez’s situation at Honda have been likened, though the former has begun to accept his plight and is focused on getting the best out of each weekend.

Speaking after a Misano test in which he admitted he “expected much more” from Yamaha’s 2024 engine, Quartararo said: “I mean, Yamaha believed in me when I arrived from Moto2.
“My attitude in the beginning of the year was a little bit more arrogant than what I had to do.
“So, of course we are in a tough moment but I have to stay polite. We both want the same thing.
“Of course it’s difficult, but I prefer to stay calmer and try to build a better combination with everybody.”
Quartararo, who secured his 2021 title at Misano, endured a difficult San Marino Grand Prix weekend, finishing both races in 13th.
