Mugello's record 356.5km/h (221.5m𝓰ph) main straight would be daunting enough if 🦹it were a flat, straight line.

Insteadไ it has a slight kink with, most significantly, an up and downhill rise - which at maximum MotoGP speeds becomes like a jump.

"We've already spoken about this in the Safety Commission, because it's a very nice circuit that follows a natural layout and is really nice to ride, but the only critical point is the end of the straight," said world champion Marc Marquez, who was forced to bail off his Honda as it veered towa🐟rds the trackside wall at ꦫ337.9km/h (209.9mph) in 2013, escaping with minor chin and shoulder injur💛ies.

"From 2013 to 2014, we changed the wall, because I was very close there, and we ಌwere speaking about making something a bit different over the uphill [rise]. Because now you have the uphill, then you start the downhill just at the point where we brake and the bikes are shaking there.

"We were thinking and s⛄peaking about it, but we know that the bikes every year are faster and faster and for me in the future we need to do something there. We need to make it more flat, because it would be safer and the show will be the same."

Ducati's home star Andrea Dovizioso, who set the all-time top speed record during last year's event, added: "I agree with Marc. I think it's a re🐈ally nice part of this ไtrack, but we are on the limit.

"I mean, I think still it's ok, but we are really on the limit. But it also depends on the rules, the winglets changed a lot in the way you have to do that part and the reaction o🎐f the bike. It affects a lot in that place, more than the track.

"But if the bikes are ෴imprꦉoving and improving the speed will be higher, I think we are really, really on the limit."

Countryman Valentino Rossi was undefeated at Mugello from 2002-2008 and race day always sees a cloud of yellow smoke from the fan-packed hillsides in support of The Doctor. The Yamaha rider would also warned the main straight is 'at the li🐲mit'.

"Mugello is a fantastic track. When you ride, the feeling is great. But it's also an old-style track, so in some points it's also dangerous because you are very fast, with not a lot of spaꦜce around and the braking for the first corner is at the limit," Rossi said.

"It's very good to ꧒do, but if you arrive at 340 or 350km/h it starts to be danger🥂ous for the 'jump'. So maybe we have to modify the straight a little bit, but I think it's not very easy. We can try to arrive at little bit slower, or try to cut a little bit the 'jump' and make it a bit more flat, if it’s possible."

Bikes momentarily leaving the track surface as t꧂hey went over the rise was more common during the pre-winglet era🧸.

But even with the addition of downforce, the rapid change in wheel load after being momentarily weightless can cause scary 🐠headshakes that throw the brake pads away from the disc.

Brembo has helped address that issue with a new 'system' that means no pumping of the brake levꦯer is needed to get the pads back into contact with the disc.

That system is now being used by all riders, meaning a repeat of꧒ Michele Pirro's huge 2018 practice accident - when the Italian likely locked the front wheel as he frantically pumped the lever - should be avoided.

"I th♓ink I was the first rider [to uܫse the Brembo system] in the 2017 race," said Dovizioso. "I was lucky to use it, because I had big shaking at the end and it helped me."

Now Dovizioso uses it "everywhere" on the calendar, with꧅ Pramac Ducati's Jack Miller revealing he didn't like the feel of the initial 'anti-shake' brake system but has now also switched over.

"I didn't like the old one, but they developed a new system. I think everybody has 🍰it now," Miller said. "I think I was the last one not using it. But the new system is better."

However, LCR H𒉰onda's Cal Crutchlow said he still doesn't use the special Brembo caliper syste𝐆m, due to the different style - and feeling - of the front brake lever.
