Without ABS the locked up tyre will still push back against the bike, causing it to slow down, just without much control over it heading left or right.
#Motorcycle anti lock braking system Patch#
Rather than a rotating tyre applying a force left or right, which you are in control of via the handlebars, all you have is one patch of rubber trying to grip the road. To understand why it's a good idea let's consider what happens if you apply the front brake really hard to the point where it completely stops the wheel turning. Here's a quick ABS versus non-ABS video from Honda.
It basically takes a sudden fist full of brake and spreads it out a bit so the bike still slows down, just without one of the wheels locking up.
When activated the system quickly holds and releases pressure on the brake calipers gripping the brake disc in order to apply a slower and more intermittent braking force. If the computer notices a sudden and large difference in front/back wheel speeds while the bike is slowing down this might indicate that a wheel is about to lock and the ABS system should kick in. You can usually spot the measuring disc and extra cable heading up from the brake to the bike (check out the header image above). A sensor reads how fast these fly past in order to calculate wheel speed at the front and rear of the bike, which is then fed into a mini computer system in the main section of the bike.
Standard ABS systems use a little wheel with regular holes or raised sections within the brake discs. On motorbikes and scooters ABS, short for Anti-Lock Braking System, is there to help you brake hard in an emergency or to avoid a crash.
