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.
For the MotoE 2023, Ducati has defined specific requests for the braking system on which Brembo has sized and manufactured the individual components.
The Ducati MotoE system at the front is composed of a double 338.5 mm diameter steel disc with a thickness of 6.8mm, which has fins on the internal diameter in order to increase the heat exchange surface and improve disc cooling in conditions of extreme use on track. The double steel disc is provided with two GP4RR M4 32/36 calipers with PR19/18 radial master cylinder.
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.
On the Ducati MotoE, the rear brake is no longer mechanical, but 'electric'; the braking action is achieved through the electronic management of the motor. This system has two advantages: saving weight, around 1,6kg, and recovering energy by making the electric motor work like a generator when the rear wheel slows down.
However, some riders may want the mechanical rear brake, to use it above all during acceleration to vary the set-up of the bike. Brembo therefore supplies, as an option for each bike, a single disc system with a 220 mm diameter and 5 mm thickness and a P34 caliper actuated by a PS13 master cylinder.
The riders of the MotoE also ride in other competitions, and some of them are used to using the rear handlebar brake. Since the MotoE is clutchless, the left handlebar is free, so some riders may choose to have the rear brake control lever there.
Also on the Ducati prototype there is the possibility of having the rear brake control on the handlebar; it is the teams who choose whether to adopt them or not. The foot lever remains, and the rear caliper is controlled by the lever on which the rider applies more pressure (the lever on the handlebar or the one on the footpeg).
Originally, during the first 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 fell on thicker discs. large with better heat dissipation qualities.
