The 2021 world champion came into the Italian GP weekend carrying the set-up he used that year having found none of Yamaha’s 2023 developments worked in previous rounds.
But this failed to transform his fortunes as he could only qualify 15th behind team-mate Franco Morbidelli and could manage only 10th in the sprint and 11th in the grand prix.
Quartararo raced the medium rear tyre having preferred the soft, and ended up stuck behind Ducati’s Enea Bastianini for much of the grand prix.
“Yes, really difficult because also in the warm-up I didn’t feel great with the medium,” he said.
“I was feeling much better with the soft, but the team thought the soft wasn’t going to handle [the heat].
“I was feeling great, but we chose the medium but for me it was not the best decision.
“It was difficult, I was behind Enea the whole race and wasn’t able to try an overtake. So, really difficult Sunday.”
