MotoGP Mugello: Aprilia’s F1-style rear wing ‘makes the difference’ | MotoGP

The device appeared on the back of test driver Lorenzo Savadori’s RS-GP during Friday’s testing in Italy.

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

“I couldn’t try the rear wing, but I saw the wind tunnel data and it’s interesting,” Espargaro said. “It looks like it’s just pure marketing, but believe me, it makes a difference.

“Yes, it reminds you of Formula 1, but it gives a lot of weight in some places and now in MotoGP we talk about details.

“We are missing a bit of weight at the back. That’s why I can’t increase engine braking, so I pushed them up to create more rear load.

“They are working in different areas to improve that and a [solution] was aerodynamics.

But after having such a strong start to the weekend, Espargaro believes he will now postpone testing the device on his own until the Catalunya test.

“Maybe the plan was to try tomorrow but the bike is working well and I’m fast so I’ll wait,” he said.

A new innovation from Aprilia that Espargaro used on Friday was an improved engine.

“I tried the new engine. It’s not a huge difference but you could see that the top speed of Maverick, Lorenzo and I was quite fast. Over 350 and very close to the Ducati,” he said.

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

“But the bike is fast, and I hope it helps me on Sunday.”

Espargaro’s teammate Maverick Vinales was 17th fastest with Savadori 26th and last.

“Today we mainly tested the new aerodynamic element brought by Aprilia,” said Savadori. “There is still work to be done to make it more efficient.

“That’s why I didn’t focus on time trial or pure speed, but I’m extremely happy to be here at Mugello and to see Aleix competitive again.”
