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 ღto prepare many fairings, get all things⛎ painted, in just one week.

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

“I was happy to feel some𒅌 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 po🌱sitive 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 curious to see if this difference we got will be a big help 🍃in the ra🔴ces here.”
