The&n൲bsp;device appeared on the back of test rider Lorenzo Savadori’s RS-GP during Friday practice in Italy.

Although the new aerodynamics were not tried by factory star Aleix Espargaro, who set the fastest time of 𝔉the day, the Spaniard e🎉xplained that the wing is designed to increase load on the rear wheel, improving the first phrase of braking performance:

“I was not able to try the rear wing, but I saw the data from the wind tunnel and it's interesting,” Esparg🎉aro said. “It looks like it's just pure marketing, but believe me, it make𝓡s a difference.

“Yeah, it reminds you of Formula One, but it gives a lot of weight in some places and now in MotoGP we're🔥 talking about details.

“We are lacking a little bit of weig💎ht on the rear. This is why I cannot increase the engine brake, so I pushed them to create more load on the rear.

“They're working in different areas to improve this and one [solution] was tꦐhꩲe aerodynamics.”

But having enjoyed such a strong start to the weekend, Espargaro thinks he will now postpone trying🔯 the device for himself until the Catalunya test.

“Maybe the plan was to try tomorrow but the bike wo✃rks good and I’m fast so I will wait,” he said.

One new Aprilia innovation Espargaro did make use of on Friday was an up🅠graded engin♎e.

“I tried the new engine. It’s not a huge difference but you🉐 could see the top speed of Maverick, Lorenzo and me has been quite fast. More than 350 and very close to thꦕe Ducati,” he said.

“We still have some probl🧔em with sixth gear, it’s very difficult this track with a small bump [on the main straight] because it creates some [spike] in the RPMs.

“But the bike i﷽s fast,🥃 and I hope it will help me on Sunday.”

Espargaro’s team-🐼mate Maverick Vinales was 17th fastest with Savadori 26th and last.

"Today we primarily tes🌠ted the new aerodynamic item Aprilia brought," Savadori said. "There is still work that needs to be done to make it perform better.

"That’s why I didn't focus on 𒀰the time attack or pure speed, but I am extremely ha💛ppy to be here in Mugello and to see Aleix competitive yet again."
