Anti-lock Brake System (ABS) Management
Anti-lock Brake System (ABS)
System Description
This model is equipped with a partially integrated braking system, combined with the
Anti-lock Braking System (ABS). This increases the braking efficiency when riding the
motorcycle.
When the front brake is applied, a small amount of rear brake is also applied, allowing
for balanced braking. The amount of rear brake application is related to the level of
braking force applied by the rider through the front brake lever. Use of the rear brake
pedal alone will only apply the rear brake.
Partially Intergrated Braking System
ABS
This model is fitted with an electronic anti-lock brake system which is designed to
prevent the wheels from locking or skidding by reducing braking effort to the front or
rear brake caliper as required.
The system consists of a hydraulic modulator and ECM assembly mounted to a bracket
beneath the fuel tank, a front wheel speed sensor mounted to the front fork, and a rear
wheel speed sensor mounted to the final drive.
The front wheel has a pulser ring mounted on to the wheel hub. The rear wheel pulser
ring is mounted to the cush drive.
The front and rear master cylinders are connected via lines to the modulator and from
the modulator the lines connect to the brake calipers.
The ABS modulator ECM continuously calculates the front and rear wheel speeds, and
from these inputs the ECM calculates the estimated motorcycle speed, wheel
deceleration/acceleration, the wheel speed difference and the wheel slip (skid) rate. This
is calculated by comparing the calculated wheel speeds with the calculated vehicle
speed, so that if one wheel speed deviates significantly from the other two readings, this
wheel is calculated to be slipping (skidding).
Under braking, if the modulator detects that either wheel is slipping, due to the brake
force exceeding the available traction between the tyre and road surface (the wheel will
