The 2016 MotoGP World Championship will make a stop at the Bugatti Circuit (France) for its fifth round this weekend, May 6-8.
Built in 1965 around the track used for the 24 Hours of Le Mans, this circuit held its first World Motorcycle Race in 1969. For years the location of the Championship alternated among the Bugatti, Paul Ricard and Nogaro tracks, but after improving safety conditions, Bugatti has continuously held the event since 2000.
The Bugatti circuit is 4.2 km long (2.6-miles), boasts 14 curves (9 to the right and 5 to the left) and comprises a main straightaway that measures 674 meters (2,200-feet).
Le Mans is a track that has a medium impact on the brakes. In spite of the fact that about 30% of the lap time is spent braking on this French circuit, the riders are able to effortlessly cool down the Brembo carbon brake discs thanks to the long straightaways.
To prevent the discs from cooling excessively, which could jeopardize the effectiveness of the brakes, larger diameter Brembo discs (340 mm) with a low band may be the most suitable solution for this track’s specifications. Indeed, this solution could guarantee the proper functioning range in terms of operating temperature and braking torque.
According to Brembo technicians, the Bugatti Circuit falls into the category of tracks that have a medium impact on the brakes. On a scale of one to five it earned a three on the difficulty index, the same result that the tracks at Losail, Austin and Termas de Rio Hondo scored.
Brake use during the GP
The Bugatti Circuit doesn’t let the bikes reach great maximum speeds (they peak at 316.6 km/h or 196 mph) because, with the exception of curves 1 (Dunlop turn) and 12, all of the other braking sections require the use of the brakes for …read more
