OUTLINE OF THE ABS

1. This model is equipped with the latest, advanced type of ABS, which has improved feeling during

operation and smoother braking than previous ABS brakes. The ABS ECU detects the hydraulic

pressure using the pressure sensors and controls the pressure linearly using continuously variable

adjustments to obtain the appropriate pressure when the wheels have a tendency to lock or accord-

ing to the operation input (hydraulic pressure) from the brake lever or brake pedal.

2. If the wheels have a tendency to lock during brake lever input, brake pedal input, or UBS control, the

ABS will operate.

3. The hydraulic unit assembly, which is the main component of the ABS, is centrally located on the

vehicle to increase mass centralization.
