Yamaha ABS features
1. The Yamaha ABS (Anti-Lock Brake System) features a dual electronic control system, which acts
on the front and rear brakes independently.
2. The ABS features a compact and lightweight design to help maintain the basic maneuverability of
the vehicle.
3. The hydraulic unit, which is the main component of the ABS, is centrally located on the vehicle to
increase mass centralization.

The operation of the Yamaha ABS brakes is the same as conventional vehicle, with a right hand
brake lever for operating the front wheel brake and a left hand brake lever for operating the rear
wheel brake.
When wheel lockup is detected during emergency braking, hydraulic control is performed by the
hydraulic system independently.

The ABS also includes a highly developed self-diagnostic function. The ABS detects any problem
conditions and allows normal braking even if the ABS is not operating properly.
When this occurs, the ABS warning light on the meter assembly comes on.
The ABS stores the malfunction codes in the memory of the ECU (ABS) for easy problem identifica-
tion and troubleshooting.
