Understanding the Working Rule of ABS Braking Framework on Bikes
Cruisers are quick, spry and fun to ride, but they can moreover be perilous on the off chance that the rider loses control. One of the foremost basic components of any bike is the braking framework. Without it, the rider is incapable to moderate down or halt the bicycle, which can lead to mishaps and wounds. The Anti-lock Braking System or ABS may be a security highlight that has revolutionized the way cruisers are ridden. In this article, we’ll dig into the working rule of ABS braking system on bikes.

What is ABS Braking Framework?

The Anti-lock Braking Framework (ABS) may be a security highlight that anticipates the wheels of a bike from locking up amid braking. This feature ensures that the motorcycle maintains solidness and steerability, indeed when the brakes are connected all of a sudden or on elusive surfaces. ABS was to begin with presented within the car industry within the 1970s and afterward got to be prevalent in cruisers.

How Does ABS Work?

The ABS braking framework works by utilizing sensors to identify the speed and turn of the motorcycle’s wheels. When the rider applies the brakes, the ABS controller analyzes the information from the sensors and decides in the event that the wheels are approximately to bolt up. On the off chance that the controller recognizes that the wheels are around to bolt up, it quickly discharges and reapplies the brakes, up to a few times per moment. This handle is known as balancing the brake weight.

Components of ABS Braking Framework

The ABS braking framework comprises of a few components that work together to ensure safe and compelling braking. These incorporate:


ABS braking framework on motorcycles have wheel sensors that distinguish the speed and turn of the wheels. These sensors send signals to the ABS controller, which employments the data to determine if the wheels are approximately to bolt up.

ABS Controller

The ABS controller is the brain of the ABS framework. It gets signals from the wheel sensors and decides in the event that the wheels are around to bolt up. If the controller identifies that the wheels are approximately to bolt up, it tweaks the brake weight to anticipate locking.

Hydraulic Unit

The water powered unit is mindful for applying and discharging the brakes in reaction to the signals from the ABS controller. It comprises of a pump, engine, and valves that control the brake liquid weight.

ABS Modulator

The ABS modulator may be a valve gathering that balances the brake weight to avoid wheel lock-up. It is controlled by the ABS controller and works in conjunction with the pressure driven unit.

Preferences of ABS Braking Framework

The ABS braking framework has a few preferences over conventional braking frameworks, counting:

Expanded Stability

The ABS braking framework anticipates the wheels from locking up amid braking, which progresses soundness and steerability of the cruiser. This permits the rider to preserve control of the cruiser in crisis braking circumstances.

Shorter Braking Remove

The ABS braking framework diminishes the braking separate by anticipating wheel lock-up, which suggests the rider can stop the cruiser more quickly.

Increased Safety

The ABS braking framework could be a security include that decreases the chance of mishaps and wounds. It permits the rider to preserve control of the cruiser amid crisis braking circumstances and on elusive surfaces.

Drawbacks of ABS Braking Framework

Whereas the ABS braking framework has numerous points of interest, it too has a few drawbacks, counting:


The ABS braking framework is more costly than conventional braking frameworks, which can make it more troublesome for some riders to manage.


The ABS braking framework requires more support than conventional braking frameworks. The sensors and valves can gotten to be clogged or harmed, which can influence the system’s execution.


The ABS braking framework includes weight to the cruiser, which can influence taking care of and execution.

Working principle

Thanks to ABS, the car does not skid when braking sharply.
The need for ABS is most evident when the vehicle is difficult to brake, slippery or wet roads or unexpected braking situations. When braking sharply, it causes wheel lock, ie the brake pads stick to the brake disc, preventing the wheel from turning, losing traction leading to an accident.

The role of ABS is to detect a bad braking situation first as soon as it actually happens based on the braking force as well as the wheel rotation speed. When ABS is activated, the system maintains the wheel’s slip with the road surface within the allowable limit.

Working principle

The biggest problem with skidding is losing control for a fraction of a second. Can you both keep the car level and restore the engine’s traction, while the wheels are still sliding? The answer is yes, but only for professional motorcyclists and drifters who experience a lot of accidents during practice. With “normal” drivers, that’s not possible.

Therefore, ABS will support by pressing-release continuously, limiting the force acting on the brake disc when the driver squeezes or steps on the brake too quickly, the force is too great and keeps the wheel still spinning. After the hazardous situation has been avoided, the system will re-apply maximum braking force to bring the vehicle to a quick stop or until a new wheel lock hazard is detected.

How does ABS know the wheel is about to lock?

If in the past the system was completely mechanical, the accuracy was not high and the delay was large, but today, electronic technology helps ABS to accurately recognize in a small split second. Basically, ABS has four main parts: sensor, controller, hydraulic pump and brake force adjustment valves.

Sensor: Electronic sensor system helps ABS accurately respond to detected phenomena when braking force, rotational speed, balance ability, and slippage are not within normal safety limits.

Sensor on the front disc.

The main component in the sensor is the speed sensor type. Motorcycles equipped with ABS are easy to recognize by the special structure of the brake disc, which is a small disc with gaps close to the wheel’s axis of rotation that can be detected by ordinary observation. These gaps, called pulse rings, are responsible for measuring the speed sensor. In the same time period, the more times the sensors read the speed signal together, the better the accuracy.

The continuously measured speed provides information to the ECU controller. While some cars have only one-wheel ABS, others have both-wheel ABS, where the controller receives signals from both wheels and compares whether there is a deviation or not.

It is worth noting that the speed measured at the wheel axle is not strictly the actual travel speed of the vehicle. Therefore, when the wheel slips or locks, ie there is a difference between the vehicle speed and the wheel rotation speed, ABS will recognize and react to activate or not. Along with the speed sensor, there are gyro and lay sensors that re-determine the angle of inclination when cornering.

Controller (ECU): Electronic Control Unit is the electronic control unit, the brain of ABS. The task of the ECU is to receive, analyze and compare the information sent by the sensor. In the event that the vehicle is found to be in an unsafe state, the ECU will instruct other components to activate.

The ECU receives information and has a good “memory” ability. Based on a set of parameters received from an ABS activation, the ECU will remember it for the next time, when it understands a similar situation.

Hydraulic pump and regulating valves: The hydraulic pump here, as in any other disc brake system with a piston and cylinder, regulates the amount of oil applied to the brake pads. When the braking force is too large compared to the safe level, the help of an adjustment valve will be needed.

A group of valves will be moved to the required positions where less force can be applied to the brake pads. When the ability to skid is no longer available, the valves will move to another position to help restore the strongest impact force to help the vehicle stop quickly. This process takes only a fraction of a second and is repeated until the vehicle reaches the most stable equilibrium.

Is ABS dangerous?

There is still a lot of controversy surrounding whether ABS takes away the excitement and real feeling of driving. But most professional drivers answer “no”. Because ABS only activates when the braking force is too abnormal, it can be harmful to the vehicle and the owner, and it is only a small event in the entire journey, sometimes it does not happen if it is not in bad conditions.

When driving through roads with lots of sand and gravel, ABS can be involved, causing a few minor troubles because the ECU makes a mistake in analyzing information about speed, tilt angle… and activates when the vehicle is not really there. in danger. For off-road vehicles when it is necessary to move through roads with constantly changing surfaces, only the latest ABS system can be applied correctly in all cases. BMW R1200GS Adventure or KTM 1190 Adventure are cars that apply this type of ABS.

Although the anti-lock braking system helps the driver a lot, it is not absolute. Therefore, the fact that many inexperienced drivers believe too much in ABS and leave safety to this technology is a big mistake. The most important thing is to train yourself to handle unexpected situations on the road.

Currently, in addition to large displacement motorcycles, high-end popular cars are also equipped with ABS such as Honda SH 150 Italy. In Europe, vehicles manufactured and sold since 2016 with a cylinder capacity of over 125 cc are required to have an anti-lock braking system ABS.


The Anti-lock Braking Framework or ABS may be a safety include that avoids the wheels of a motorcycle fromlocking up amid braking, guaranteeing solidness and control of the bike. The ABS braking framework works by utilizing sensors to identify the speed and turn of the motorcycle’s wheels, and the ABS controller decides in the event that the wheels are about to lock up. On the off chance that they are, the controller balances the brake weight to anticipate locking, resulting in shorter braking separations and expanded security.

Whereas the ABS braking framework has a few points of interest, such as expanded soundness and security, it moreover has a few impediments, counting higher taken a toll, support, and weight. In spite of these downsides, the ABS braking framework is an fundamental security highlight that can spare lives and avoid mishaps.

In general, understanding the working principle of ABS braking framework on motorcycles is vital for each rider. By knowing how the framework works, riders can make educated choices almost their security and select cruisers that have this highlight. Within the conclusion, the ABS braking system provides an additional layer of security that can make all the distinction in crisis circumstances.

ABS stands for Anti-Lock Braking System, anti-lock braking system. ABS was invented by Gabriel Voisin in the late 1920s to solve some problems in the braking system of aircraft, but it was first widely applied in the automotive industry. It took about 50 years from the invention of ABS to its use on modern braking systems.

The first motorcycle to use ABS was the 1988 BMW K100. Over a long period of time, many new technologies have been upgraded and applied to ABS, but in general, the basic operating principles are still the same. declare. To date, this is still the most advanced and safest braking technology installed on motorcycles.
