The Monster Yamaha completed 67 laps of the Barcelona circuit, the best of which, a 1m 39.477s, put him 𓆉just 0.004s clear of Ducati’s Francesco Bagnaia.

The Frenchman said he had “nothing really important to test” but did re-try a swingarm from the Jerez test, an engine map to try and fin🌜d “a bit 🌳more power”, some tyres for Michelin and a new bike set-up.

But on a day when many of Yamaha’s rivals rolled out new aero𝐆dynamics, Quartararo confirmed that he will not use his 🅷briefly seen 2022 fairing update again.

“We will never use again,” he said. “From our side of the box, we will not use again the aero package that was taken to Mugello and w♎e will always ride with our standard, with the four wings.”

The fairing update handed to Quartararo at the𝔍 Italian GP effectively looked like the previous aero but with the sidepods removed, to try and find more top speed.

But it wasn’t worth the downforce lost in the corners and, after a last-minute switch back to the o📖riginal, Quartararo took the f༒ight to race winner Bagnaia.

“From outside, it's a really small change,” Quartararo said of the unsuccessful fairing update𝓀, “but on the bike it’s quite big. I was feeling strange on the bike and in Mugello on the Sunday we said ‘OK, we go to the standard’.

“It was much better and we saw that b♓asically the goal of the [new] fairing was to be faster on the straight. And we gained 1k, but we gained🔥 1k and then we lost a lot in the turns, so we decided to go back.”

With hindsight, it would have been better to try the new fairing at an official test, as many of Yamaha’s rivals were doing i🧜n Bar🍸celona, before committing to it at a grand prix weekend.

But since the new fairing has been used by the Frenchman at a MotoGP event, no matter how briefly, Quartararo cannot have a further fairing update unt❀il the start🃏 of the 2023 season.

F1 engine designer Luca Marmorini linked with Yamaha

Upon announcing his new two-year contract with Yamaha, 👍on the eve of the Catalunya weekend, Quartararo made clear that a commitment to boost the M1’s engine performance had been key to his signature.

Although Quartararo hinted that the new engineers were ‘already within Yamaha’, rumours have subsequently emerged that former Ferrari and Toyota F1 engine designer Luca Marmorini could be set toಞ play a key role.

Although not commenting dir❀ectly on Marmorini, Quartararo said: “For me I always push, and more now, to have more power. I'm sure they are working super ꦕhard to bring us a new engine for 2023 and have much more power because I always say the same:

“If you make everything perfect, you can♐ win [now on the Yamaha]. It's not a problem of power or whatever. But when you are in a tough situation, power is something that changes your race.

“So this is why I think it's the most important to have power [for🍃 2023] and not really think about other t🅘hings.”

Having scored 45 𒈔out of 50 points at what were expected to be ‘damage limitation’ races, Quartararo will take a 22-point title lead over Aleix Espargaro into next weekend’s German round.

“We entered the Mugello and Barcelona weekend thinking that we needed to do damage limitation, but in the end we did two good races,” s🐭aid team director Massimo Meregalli. “So, we are looking forward to the next two rounds ahead of the summer break.

Franco Morbidelli: ‘We don't want a top 10, we want more’

Team-mate Franco Morbidelli, who also received the fairing upgrade at Mugello, was eighth fastest at the test, 0.348s from Quart🎉araro’s flying lap, despite a sma🔯ll crash.

“The pace was better, so I'm pretty happy with the work we've done,” said Morbidelli, who was pushed back to last on the ope💛ning lap of Sunday’s race, be❀fore recovering to 13th.

“There is still some room for improvement in some areas. Bꦇut I think we made good progress.

“If I didn't have the incident on the first lap of the race, I think I could have fought for a top-10 position, for🌠 sure. But we don't just want a top 10, we want mo♓re. So, we are working towards where we want to be.”

Morbidelli𒉰 is currently just 19th in the world championship, 125 points behind Quartararo, the rider he beat during their last 2020 season together at Petronas Yamaha.
