Silverstone MotoGP Notes: Aerodynamics, Enea Bastianini, And Why Losing A Wing Doesn't Always End In Disaster

It is no secret that aerodynamics is a big deal in MotoGP. The winglets, aerodynamics packages, and various scoops, spoons, and other attachments aimed at modifying the behavior of the modern generation of MotoGP bikes have become increasingly important.

Aero has now reached the point where it is such a major part of bike setup that it is getting hard to change without needing a lot of work to balance out the rest of the behavior of the bike. As Red Bull KTM Factory Racing rider Brad Binder explained when asked about the two different versions of KTM's aero package he has available. "I think the most important thing is to really choose one and really stick with it. Because when you do play with the aero, it has such a massive impact that your whole setup really has to change completely. So it's not so simple to say, OK, one race we'll use them and one race we won't."

If aerodynamics are that important, imagine what it's like when you lose a wing. It's done easily enough – the winglets and side pods are attached so that they will dislodge in a collision, to prevent the chance of injury – and when it does, it complicates life enormously for the rider. The bike pulls wildly to one side or another, and becomes, in the words of Luca Marini, who lost a wing at Assen earlier this year, unrideable.

Off to a rough start

Take the example of Pecco Bagnaia, who lost a wing during his very first MotoGP race back in 2019. "I lost my right wing and it was very difficult," Bagnaia said in Qatar. "I pushed in the first laps but it was very dangerous because the bike was pushing me to the left every time. I tried but it was impossible. I went wide twice."

Losing the wing changed the bike completely, Bagnaia complained. "The bike was 5mm higher without the wings and it was very difficult, because you have been working on a setting and without a little part of the bike it is completely changed. It was moving too much on the straight and when I started braking it was pushing me to the left." After 10 laps, Bagnaia believed it was too dangerous to continue, and retired from the race.

At Assen earlier this year, Luca Marini and Miguel Oliveira both lost wings to Joan Mir in separate incidents. Oliveira clipped the side of Mir's Suzuki as the Spaniard braked to set his front holeshot device, losing a side pod in the process. Marini lost his aero after the start, when Mir pulled left off the line and slammed into the side of the VR46 Ducati rider, taking his right side pod of the bike.

Though both Oliveira and Marini lost essentially the same part of the bike, the difference in outcome for the two was marked. Marini lost ground at the start, and never managed to make it up, finishing 17th, 30 seconds behind the winner Pecco Bagnaia. Oliveira managed to hang in with the group battling for eighth and crossed the line in ninth, just over 8 seconds behind the winner.

After the race at Assen, Oliveira told us that the loss of the side pod had made the KTM RC16 hard to turn. "The effect was that I lost stability in fast corners, and the bike was hard to turn on the right side. It didn't turn as much," the Portuguese rider said.

Things were much more difficult for Luca Marini. "So incredible how it affects the riding," the Mooney VR46 Ducati rider said. "Incredible. Even if this track is maybe is one of the worst to have this problem, because the speed all around the track is very high and the bike just doesn't do anything that you want to make it do."

Riders can say "bike isn't right so I parked it." or "But to make more speed was impossible, because the bike doesn’t turn, I don’t have load in the front. It was impossible." Meaning it feels different to what I'm used to.

 Enea Bastianini rides the bike he is on to the best of his ability and gets a surprisingly good result. "In the third quarter of the race, Bastianini was consistently the fastest rider on track, and one of the fastest in the final five laps". RESPECT!

I say the rider is more important than the motorcycle. But don't just take my word for it, ask Valentino or maybe Alberto at HRC.

Silverstone seems like a great circuit to ride and motorcycle racing there looks awesome on screen. But not so good for spectators at the track. That's racing.

The nagging question remains....where would he have finished if he hadn't lost the wing ? What if the answer was 10th ? You spend all weekend working on the bike in great detail...

FP1 - 16th, FP2 - 8th, FP3 - 12th, FP4 - 11th, Q1 - 1st, Q2 - 8th, WU - 11th

Then break it and finish 4th.

 

Yes! Feels like that's often overlooked. Break something off and make it better? What if he'd broken both of them - would it have been better again? Could we see riders intentionally leaning over and banging wings off on the warm up lap to avoid rules regarding 2 aero packages only?

I heard from my brother's dog's mother's owner that it has been suggested that Peco may have been seen with a small junior hacksaw tucked into his leathers apparently. The question as to whether it is for wings or handcuffs remains open.

I’ve been thinking the same about Mir’s lack of success. As his manager suggests it’s either HRC or going home for next year.

Perhaps it’s time to begin a new career for the newly married Joan Mir, something less fraught with danger. Surely Suzuki must have paid well over the past 4 years.
