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

Zarco had said about the aero: “The most difficult thing to get this aero, that was good in Mugello, is to prepare many 𒅌fairings, get all things painted, in just one week.

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

“I was happy to feel some differences. I got the bike turning better. Really that 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 positive way. It's o🏅ne♚ thing that I think they can homologate and then see better [how it works] for the rest of the season.

“I'm curi💖ous to see if this diff♔erence we got will be a big help in the races here.”
