Admittedly, the 298.3km/h set with a prototype version of the 2023𒁏 Yamaha engine, behind🍬 only a 300.0km/h by Ducati’s Jorge Martin, had been in the slipstream of team-mate Franco Morbidelli.

But it was still a major step compared to his 20th place on the speed charts with the 🍬current much-maligned engine during the San 🎶Marino grand prix weekend.

Quartararo’s average speed with the new engine on Wednesday morning, a more accurate figure since it 💟uses the top five speeds for each rider, was also promising at 296.3km/h compared with a best of 298.6km/h by Martin.

“This morning we worked pretty well on the electronics of the new bike because the charac📖ter of the engine is slightly different,” said Quartararo. “The top speed looks really good, so I feel super happy! It‘s a great feeling.

“I got a great slipstream to set the 298km/h top speed this morning. But the average of the speed was also ꦯgood, compared to the others, this is super important.

“We still need to work on the first part of acceleration and impr𒁃ove more. But we are only in Se🍬ptember. We still have the Valencia test, then Sepang and Portimao.”

Having lost points to Ducati’s Francesco Bagnaia at the last four races, Quartararo then𝓀 completed a morale-boosting day by also topping the afternoon session - when he tried some ne🌳w fairings and winglets - with the fastest lap of the test.

“The difficult thing will be ꦅto be back in Aragon on the 2022 bik🍎e!” Quartararo said.

Mixed opinions on new Yamaha chassis

While the new engine and aerodynamics can’t be used until next seaso🅺n, Quartararo also had a new chassis that will at least be on standby for next weekend in Aragon.

“Fabio is really considering to use it,” confirmed tౠeam director Massimo Meregalli.

“This chassis has something good and bad, like always. Fabio thinks it’s more good than bad and Franco [Morbidไelli] the opposite. He was not feeling as good as Fabio.

“But it will be important to evaluate it in Aragon, because it’s not enough to evaluate a ♔new chassis or an engine at a single⭕ track.”

Morbidelli set the 12th fastest lap of the test, 0.560s behind Quar🦄tararo.

“Unfortunately, the hot lap didn't come out well. But anyway, our pace and our av🍸erage level w꧅ere really good. We found many different solutions. They are all interesting, so we need to make the right choices,” Morbidelli said.

“The team and Yamaha did a wonderful job in st🐻epping up in terms of items for the bike. They did a great job at home, and these two days of testing were really good to appreciate the job they did.”

Aragon was one of Yamaha's toughest events last season with Quartararo the only M1 ✅in the p✃oints with eighth place, while Bagnaia won his first MotoGP race.
