Brembo's braking system for the Ducati MotoE
The Brembo braking system of the Ducati MotoE - In MotoE, braking has always been a very delicate phase due to the high weight of the bike: 260kg in the first three years, 247kg in the fourth year and 225kg starting from 2023 for the MotoE of Ducati. To these values, it must be added the weight of the rider, therefore at least another 70kg. Considering the maximum speed reached by the MotoE (about 275 km/h), we understand how the braking system plays a fundamental role in the riding and safety of these bikes.
Brembo is the technical partner of MotoE since its debut, which took place in 2019 with the Ego Corsa di Energica Motor Company, and continues to supply braking systems also in the cycle of the MotoE World Championship which sees Ducati as the sole supplier starting from 2023.

Brembo's braking system for the MotoE first generation (2019 to 2022)
For the MotoE 2023, Ducati has defined specific requests for the braking system on which Brembo has sized and manufactured the individual components.
The system for the Ducati MotoE is composed of a double steel disc 338.5 mm in diameter with a thickness of 6.8mm, which has fins on the internal diameter to increase the heat exchange surface and improve the cooling of the disc in conditions of extreme use on track. These two steel discs are coupled to two GP4RR M4 32/36 calipers with a PR19/18 radial pump. At the rear, the P34 caliper acts on a 220mm diameter and 5mm thick single disc unit with a PS13 pump.
Each disc is made up of eight "T" pins obtained on the disc and eight shapes on the bell, which allow the elimination of the drag pawls. According to Brembo, this particular shape allows the braking torque to be transmitted more effectively, through a specific study of the machining tolerances.
The “T-Drive” offers high resistance to thermo-mechanical stress, especially in the most extreme conditions of use. It also allows both radial and axial floating and allows reducing the overall weight of the disc, bringing a consistent advantage in rideability.
The riders of the MotoE also ride in other competitions and some of them are used to having a rear brake lever on the handlebar. Since the MotoE doesn't have the clutch, the left handlebar is free, so some riders in the past have asked to have the rear brake control lever there.
On the Ducati prototype, it is also possible to have the rear brake control on the handlebar; the teams will choose whether to equip their bikes with it or not. However, the control by the right foot remains, and it is the control on which the rider exerts more pressure to control the rear caliper (the lever on the handlebar or the one on the footboard).
At first, during the tests carried out by Alex De Angelis on the Vallelunga track, Ducati had mounted a pair of 327mm diameter and 7,1mm thick discs on the front without cooling fins but the final choice was to use larger discs with better heat dissipation properties.
