Large motorbikes on the road must be fitted with ABS, a new measure that will be implemented from 2025!
According to Transport Minister Datuk Seri Najib Tun Razak, large motorbikes of 150cc or above will be required to be fitted with anti-lock braking systems (ABS), which will apply to both imported and locally assembled motorbikes.
The Malaysian Institute of Road Safety Studies (MIROS) will conduct a six-month study followed by a two-year buffer period to give motorbike manufacturers enough time to install ABS on new motorbikes.
When the speed of a moving vehicle increases or decreases, the coefficient of friction between the tyres and the ground changes, i.e. tyre slippage occurs. In the event of emergency braking, the brakes lock up the wheels and the vehicle slides like a block of ice on a flat surface, its trajectory uncontrollable. the function of the ABS braking system is to prevent the brakes from locking up and to give the vehicle the ability to control its direction when braking.
A tyre tachometer sends 90 to 100 pulses over approximately one week of wheel rotation to measure the angular speed and angular acceleration of the tyre rotation, while a brake pressure regulator determines whether to release pressure to allow the tyre to roll the brakes in the optimum range.
In cars fitted with ABS, the brakes can be applied 60 to 120 times in a second when the wheels are about to reach the next locking point. This corresponds to continuous braking and relaxation, similar to what is commonly referred to as “spot braking”. This prevents loss of direction and wheel spin during emergency braking and keeps the wheels from locking up during braking, resulting in braking efficiency of over 90%.
