ANTI-LOCK BRAKING SYSTEM

Anti-Lock Brake System (ABS)

Your motorcycle is fitted with a Single Channel Anti-lock Braking System (ABS) in the front brake system which is
designed to prevent skidding and help riders to maintain steering control during emergency-stopping situation in dry
or wet roads, loose gravels etc.

How does ABS work?

When a rider applies the front brake continuously, as he detects a dangerous obstacle in dry or wet roads, loose
gravels etc. transmits an excessive brake force to the wheel. This excessive force may cause the wheels to stop
spinning and leads to lose of road grip. With no firm contact between the tire's contact patch and the road surface,
the bike becomes unstable and a crash is imminent.
The slipping wheels on a riding surface results in losing control of whole motorcycle which usually occurs in fractions
of a second. Restoring traction while keeping the bike balanced is only a result of luck, or extreme training, as is
the case of professional stunt riders who drift. Preventing the wheels from slipping due to excessive braking force
compensates losing control and help the rider to maneuver the vehicle and to avoid accidents.
So what the ABS does is actually limiting the braking force exerted by the rider by either squeezing the lever and keep
the wheel spinning. Once the imminence of the locking (and therefore skidding) is avoided, the system re-applies
the maximum braking force until the next skid is anticipated. By limiting the max force of the braking maneuver, the
ABS systems practically allow the riders to use the greatest stopping force possible without locking the front wheel.

How does the ABS understands the wheel locking?

The ABS uses continuous wheel speed monitoring system; wheel speed sensors and toner rings and a Hydraulic
Electronic Control Unit (HECU).
During normal operation the ABS works similar to a normal brake. The speed sensor fitted on the front wheel measures
the rotational speed of the front wheel, when the wheel speed reduces rapidly i.e. wheel tends to lock, the HECU
modulates the pressure in the brake circuit and thereby prevents the wheel from locking.
