🌊Yamaha's two riders, Fabio Quartararo and Alex Rins, both used the new aero on Friday in Barcelona.

The two Japanese manufacturers both did a private test atꦿ Mugello last week, part of the concessions rules to boost their deꦡvelopment.

Honda's aero can be seen below.

LCR Honda's Johann Zarco used the aero on one of his bikes on Friday. Stefan Bradl, the test rider w꧟ho took part in Friday practice, used the aero on ♐both of his bikes.

Zarco had s🔯aid about the aero: “The most difficult thing to get this aero, that waꦡs good in Mugello, is to prepare many fairings, get all things painted, in just one week.

“I mean it was not planned to have a so good result like thi𒀰s in Mugello. So they did the maximum to get some steps [ready for] here.

“I was happy to feel some differenc🉐es. I got the bike turning better. Really tha♌t was my feeling and with all the analysis that they are doing on the data after the test, they can confirm it.

“So it's on the ﷺpositive way. It's one thing that I think they can homologate and then see better [how it works] for the rest of the season.

“I'm c🌳urious to see if this difference we got will be a b🐽ig help in the races here.”
