Thanks to the experience accumulated in 44 world championships in the premier class (MotoGP and 500) during which motorcycles with Brembo brakes have won 33 riders ‘world championships, 34 constructors’ world championships and triumphed in over 500 GPs with the main teams protagonists, Brembo will also supply customized braking systems in 2022 to all 24 riders who will participate in the 21st MotoGP championship, a class introduced in 2002 to replace the prestigious 500.
The 12 teams have decided to rely once again on the high levels of performance, reliability and safety guaranteed by the components of Brembo braking systems: brake calipers, brake discs, master cylinders, clutch pumps and pads.
During the 2022 season, Brembo’s wide range of technical solutions will allow each rider to customize the braking system of their bike according to their riding style, track characteristics and race strategy, combining the best features of the brake system components.

GP4 caliper
Most riders will continue to prefer the use of the GP4, the new 4-piston caliper dedicated to the MotoGP championship introduced in 2020: it is a one-piece aluminum caliper entirely machined from solid, with a 4-piston radial attachment. It has become the reference caliper for most MotoGP riders, although some of them continue to prefer the use of the 2019 caliper for reasons of habits and different performance of the bike itself.
The GP4, in addition to being characterized by an extreme design – the presence of fins on the external body – has an innovative design: it is an amplified caliper with an anti-drag system. The caliper is characterized by a system that allows to amplify the braking torque: this particularity, during the braking action, allows to generate a force that is added to that created by the hydraulic pressure of the brake fluid on the pistons. Therefore, with the same force on the pilot lever, the braking torque is amplified.
The anti-drag system, on the other hand, thanks to a spring device, allows to strongly reduce the residual torque phenomenon and avoid contact between pads and disc in the absence of pressure in the system: this avoids the formation of unwanted forces that tend to slow down. unintentionally the bike.

Twelve solutions of carbon brake discs
Brembo offers teams a wide choice of brake discs: six disc geometries and each disc geometry with two material specifications (High Mass and Standard), for a total of twelve solutions.
Most riders should focus on 340mm discs, splitting between High Mass (high-end) and Standard Mass (low-end). Some teams will continue to use 320mm Standard and High Mass discs.
Among these six geometries there is also the novelty that Brembo will make available to the teams starting from this season and which has already been tested during the Sepang and Mandalika tests: it is a ventilated carbon disc with a diameter of 355 mm. . The characteristic of this disc is precisely the greater ventilation which aims to increase the heat exchange and therefore improve the cooling of the disc itself. This is a solution designed ad hoc so that teams can use it in circuits that are expected to be very severe for the braking system such as Spielberg, Motegi, Sepang or Buriram.
This solution is also available in the 340 mm diameter disc version, already introduced in 2021 in Austria: compared to the 320 mm disc and the 355 mm disc, this is therefore the only disc within the range offered by Brembo , which comes in both standard and ventilated formats, depending on the preference of the teams.
Brembo recalls that carbon ensures a triple advantage: reduction of unsprung masses, identical coefficient of friction from start to finish and absence of residual torque problems that can afflict steel discs.

The importance of the braking feeling
Brembo, thanks to the different types of brake master cylinders made available to the teams in terms of wheelbase, is able to adapt both the race and the “reactivity” of the command according to the rider’s feeling. On each bike there is also the remote adjuster, used by the rider with his left hand to adjust the position of the brake lever, even with the bike in motion.
Brembo reports that over a third of MotoGP riders regularly use the thumb master cylinder. This technical solution, introduced by Brembo in the 1990s to help Mick Doohan, allows the rear brake to be activated by pressing a special lever on the left half-handlebar.
There are two variants of the thumb pump system in use in 2022: the most common is characterized by a single thumb pump and pedal circuit, using a rear two-piston caliper. The alternative, on the other hand, has two separate circuits, each of which acts on two of the four pistons of the rear caliper. In the first case one system excludes the other, in the second they can operate simultaneously.
Another variant of the classic thumb pump is the push & pull pump, introduced in 2019: designed with a new design optimized to ensure maximum efficiency, it has double operation and can be operated with both thumb and index finger, depending on the preference of the pilot. The use of this pump by means of the index requires that it be mounted on the lever with a rotation of 180 ° compared to the use with the thumb: this increases its modulation and grip on the lever during deceleration.

The Marchesini rims
Also for the 2022 season Marchesini forged magnesium rims equip most of the MotoGP riders, 8 out of 12 teams. Marchesini wheels are 5-spoke Y or 7-spoke for the front and 7-spoke for the rear. . The Marchesini rims, a brand of the Brembo Group, ensure weight savings for the motorcycles, favoring acceleration and handling when changing direction and during the most critical phases: when entering corners with the brake on, when cornering at high roll angles (up to 60 °) and at the exit of the bend with the throttle open, always with the bike tilted.

Brembo strengthens its commitment also in Moto2 and Moto3 with the presence of SBS Friction and J.Juan
After the tests carried out in Jerez and Portimao, Brembo confirms its presence as a leader in braking systems even in the minor categories of the World Championship.
The Bergamo-based company will supply 100% of the teams with calipers, about 50% with steel discs, 80% with pads, 90% with pumps and just under 50% with Marchesini rims to the 15 Moto2 teams and 15 Moto3 teams that will compete in 2022.
SBS Friction and J.Juan, the two brands recently acquired by the Brembo Group, also provide an important contribution to some Moto2 and Moto3 teams. Specifically, SBS Friction is a leader in the development, production and sale of aftermarket brake pads and friction materials for motorcycles, scooters, ATV / UTV, special cars and industrial applications while J.Juan is a leader in the development and production of braided brake hoses. metal and components of braking systems for the motorcycle sector.
