As we saw in the article “WHAT ARE THE TYPES OF MOTORCYCLES AND THEIR USES” at the time of buying a motorcycle it is very important to be clear about the use we are going to give to the vehicle. It is key to choose the type of bike and then the brand and reference. The Innovation Center for Motorcyclists and AIROBAG developed this quick guide so that you can find out which are the braking technologies and technological trends in motorcycle safety and make a good choice when buying one.
A bad choice of the type of bike can generate a negative experience from day one.
Both motorcycles and cars use the same types of brakes, disc and drum. Although both use the same principle of friction and pressure to stop the vehicle, the performance of disc brakes is far superior due to their greater braking power, consistency over long trips, and less maintenance.

Below, we explain how each of these systems works:
Disc brakes: They are composed of a rotor or disc that is fixed to the rim and a caliper or caliper that is secured to the suspension, there are two types: hydraulic and cable, the first being the best because the pads exert greater pressure on the disc, the operation of this system is quite simple.
The hydraulic systems, when pressing the lever or the pedal, a hydraulic pump compresses the oil that in turn pushes one or more pistons located in the caliper, thus pressing the pads against the disc, decelerating the wheel.
For systems driven by cable, the work of the pump is replaced by a cable, which, with the help of the lever that makes the cable, pulls a support that in turn pushes the pads against the disc.
Thanks to the exposed discs we can quickly dissipate the heat and in the case of hydraulic systems no maintenance is required between pad changes.
Drum brakes: Just like the disc brakes there are hydraulic and cable systems, but instead of using a rotor (disc) we are going to use a drum that turns with the rim and some fixed shoes in a suspension support, in this case the oil compressed by the pump pushes a shoe from one of its ends pressing them against the drum and slowing down the wheels.
Although the principle is similar in the basic design of the system and its mechanical operation, in drum brakes there is less contact surface, less pressure and higher temperature than in disc brakes, which is why there is less braking force.
Drum brakes are considered an obsolete technology and must be adjusted at least every thousand kilometers.
Technological trends in motorcycle safety
Braking is one of the most technical maneuvers when handling a motorcycle, many factors must be taken into account to use the front and rear brake, both and what the force should be applied in various braking situations and different types of floor.
CBS Brakes (Combined Brake Systems): When the front brake of the motorcycle is applied in the rider’s right hand, the pressure exerted on the lever activates the system by pressing the pads against the disc or drum slowing down the motorcycle, this would be the regular operation of any motorcycle. The difference appears when the rear brake pedal located on the rider’s right foot is activated, besides activating the rear wheel brake it also activates the front brake automatically, distributing the braking energy to both wheels, increasing efficiency and decreasing the braking distance. The system helps keep the path straight by increasing the stability of the rider.
The combined braking system, when activated in an emergency or with great force, can block the wheels and as a consequence the sliding and falling of the pilot.
ABS (Anti-lock Braking System): The ABS system works in conjunction with your bike’s traditional braking system. It consists of a pump that is incorporated into the brake fluid circuits and a sensor that monitors wheel rpm. If it senses hard braking, or if one or both wheels suddenly slow down, the ABS will go into action and interpret the wheels as about to lock up without the bike stopping. Therefore, this means that the motorcycle will start sliding on the pavement without control and without us being able to modify its trajectory causing the rider to fall. To avoid this situation, the sensor sends a signal to the ABS Control Module, which reduces the pressure on the brakes without driver intervention. All this in a totally autonomous way. With ABS brakes the rider maintains control throughout the braking and can brake the bike more quickly.
On slippery or wet pavement, a locked wheel can cause a fall quickly, with ABS the handling stability and maneuverability are not affected, if the wheels are at risk of being locked the ABS regulates the brake pressure directly and the risk of falling is significantly reduced.
MSC (motorcycle stability control): The system ensures greater stability in all driving situations. The stability control of the bike reduces the risk of falls in the curve when the wheels lose grip and slide to the outside of the bike, this happens when the pilot applies too much force on the rear brake in a curve and the wheels are not able to transfer enough lateral force to the asphalt. When the MSC system is activated, it applies the proper pressure to obtain a better performance, when braking in a curve the system reduces the tendency of the bike to recover its vertical position, this is an involuntary handling of the bike which leads it to turn in a larger radius causing it to go out of its trajectory.
The MSC adapts the braking force between the front and rear wheel delivering the safest possible deceleration.
Rollover Control: When you brake hard on a bike, the weight is immediately transferred to the front tire, which can lead to the rear wheel lifting off the road and causing the rider to lose balance and fall. Rollover control reduces the brake pressure on the front wheel by keeping both tires on the ground, significantly reducing the risk of a fall.
Traction Control: this system helps control the wheels so that they do not slip on wet surfaces when accelerating strongly, it controls the maximum torque capacity to ensure the optimal transfer of acceleration to the track; particularly when we take a curve a tire out of control can cause an accident quickly, so the traction control regulates the maximum power of acceleration, preventing the wheels from losing friction ensuring the traction and stability of the pilot’s driving.
The technology gives the pilots a greater security, providing them with systems that are invisible until the moment they are needed. These help to make the experience of riding a motorcycle unique, safe and exciting, as it should be.
If you want to expand this information and your knowledge, we have put our Virtual Program of Professionalization for Motorcyclists free of charge in which you can learn how to increase the probability of leaving unharmed in the event of a fall, skills and abilities from the hand of Xavi Vallejo (Director of Motorcycle School, Spain), know how to choose and how to buy certified protective elements and evaluate the motorcycles for their technological capacity.
The course contains four modules: basic concepts of road safety, certified personal protection elements, safe vehicles and driving techniques.
Improve your technique and safety.
