MotoGP at Motegi, all the secrets of the circuit: turn 11 from 311 to 81 km / h

Over the weekend, the world championship moves to the Japanese circuit, which requires a lot of braking. Let’s find out the route details with the data provided by Brembo

MotoGP moves east to four good players, one more exciting than the other: Fabio Quartararo and Francesco Bagnaia play for the Category One title divided by just 10 points. It starts on the weekend in Japan, at Motegi Racecourse. According to Brembo technicians who work closely with all 24 first class riders, the Twin Ring is one of the most demanding circuits on brakes. On a scale of 1 to 6, it deserves a difficulty index of 6. The MotoGP bikes use a road circuit that features a few fast and slow corners, punctuated by medium-length straight lines: there are even 7 curves that bikes under 100 km/h encounter.

How to brake in Motegi

The abundance of second gear curves in particular makes it one of the most demanding brakes due to the difficulty of cooling the discs between brakes. Up to 10 of 14 corners of the Twin Ring Motegi require the use of the brakes and for 5 of them use exceeds 4 seconds. In the first corner, braking lasts 5 seconds, and it is necessary to lose 228 km / h. Thanks to her and subsequent braking sections, the motorcyclists on each lap use the brakes for 34 seconds, which is a third of the Japanese Grand Prix. Also of note is the fifth turn braking, which requires a 5.6kg winch load while the BremboHTC 64T brake fluid reaches a pressure of 12 bar.

nine quintals

When you add up all the forces the rider exerts on the Brembo brake lever from the start to the checkered flag, the value approaches 9 and a half quintals. Of the 10 braking sections on the circuit, 5 are the most demanding on the brakes; While 2 are of medium difficulty and 3 are light. The most stressful for the braking system is the 11 turn at 90 degrees: MotoGP bikes get there at 311 km/h and brake for the 5.3 seconds needed to drop to 81 km/h. During this time, the riders exert a load on the winch of 6.2kg while the bikes are going 230m and the brake fluid pressure increases to 13.3bar.
