French GP 2023, Bugatti secrets in Le Mans with Brembo

FRANCE, FIFTH STAGE The fifth stage of the MotoGP world championship includes the French Grand Prix, at the iconic circuit of Le Mans in its short version, the Bugatti. Last year it was Pecco Bagnaia who won, two years ago Jack Miller, so a Ducati-friendly track. To remember how to handle the French track, let’s rely on Brembo, the Italian company leader in this sector and which supplies all 11 MotoGP teams. Below you will find the Bugatti Circuit’s identity card, data on all the main braking components and a video focusing on the most extreme braking on the Le Mans track. Enjoy reading!

SECRETS OF THE LE MANS TRACK

Less than a month after the famous 24 Hours that opened the World Endurance Championship, the Bugatti Circuit welcomes the French GP. According to Brembo technicians who work closely with 100% of the MotoGP World Championship riders, this track is one of the most demanding circuits for brakes. On a scale from 1 to 6, he deserved a difficulty index of 4, the highest value of this first part of the championship with Jerez.. To avoid the risk of discs overheating optimally, many operators will adopt High Mass discs, that is, with a high stopping surface. Materials that have become common even in the event of rain thanks to the use of special covers.

  • Standing category: Hard (4 out of 5)
  • Time spent braking: 32%
  • Length of cycle 4,185 meters
  • Number of cycles: 27
  • Number of brakes: 9
  • The three most challenging streams: curve 6, curve 8 and curve 11



In France, a revolution has taken place at home and MotoE could not be surpassed: after being previously recognized as the World Cup, this year the championship has acquired the title of World Championship, thanks to the improvement of the cycling performance, all. made by Ducati, as seen in the various tests carried out. All of these bikes use a Brembo braking system, starting with a double steel front disc The 338.5 mm diameter and 6.8 mm thick T-Drive features fins on the inner diameter to improve cooling. Also made by Brembo is a monobloc front caliper made from a solid GP4RR M4 32/36, with a radial master cylinder PR 19/18.

In each lap of the Le Mans circuit, drivers apply the brakes 9 times for a total of 29 seconds, equivalent to 32 percent of the entire GP. However, the application is not uniform because in the first 5 corners the brake is applied only twice and never for more than 3 seconds at a time. From curves 6 to 9, on the other hand, they are active all the time and for a long time: from 3.3 seconds to 4.9 seconds per curve.. As can be seen, this prevents the cooling of the brake and explains the great effort required for the whole system. The transalpine route is also characterized by the lack of a decrease of at least 190 km / h. The total load on the brake lever exerted by each driver from start to finish in a regular race is also high: about 9.7 quintals.



Of the 9 braking points on the Le Mans circuit, 2 are classified as requiring braking, 4 are of medium difficulty and the remaining 3 are not very demanding. The hardest stop in MotoGP is at the ninth corner: the bike goes from 292 km/h to 105 km/h. thanks to the action on the brake of 4.5 seconds when the brake fluid pressure reaches 10 bar. Pilots carry a load of 5.2 kg on the brake lever, decelerate by 1.5 g and at the same time travel 233 meters.

And in video games?

Facing the Curva 9 of the Bugatti Circuit in the MotoGP video game is not as trivial as you think: first of all you have to go to the right and then you have to look at the signs. You pass the first still under acceleration and when you see the walls of yellow-blue tires behind the second you brake hard.. When you pass under the bridge you go down the corner but without closing the road too much because the 10th turn is right hand.
