MotoGP: Braking Systems for the Motegi Tour – MotoriNoLimits

MotoGP is moving to the Far East where four GP competitions will be held this year, including Australia. According to Brembo technicians who operate In close contact with all 24 premium class riders, the Twin Ring Motegi is one of the circuits with a lot of demands on the 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. The abundance of curves from second gear in particular makes it one of the most demanding brakes due to the difficulty of cooling the discs between brakes.

Giant Brembo Motorcycle Disc

To better handle the more severe circuitry of the braking system, in 2022 at MotoGP Brembo introduced 355mm ventilated carbon discs surrounding the 340mm models. These discs have already been used in tests in Sepang, Jerez and Barcelona and in the race in Spielberg, to the satisfaction of the riders. The regulation also states that for safety reasons in the Motegi, Spielberg and Buriram circuits, riders choose between these 355mm and 340mm discs, prohibiting 320mm discs which, on the other hand, remain usable in all other GPs. The restraints are of course not valid in the case of wet sweat because the braking force is lower.

If the 355mm discs are a novelty in MotoGP history, the bike’s maximum output is certainly lower. Given the diameter, the largest Brembo floating disc is the 330mm used on the Ducati Panigale. Find out more about the Brembo two-wheel disc brake range.

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. 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.
