WARNING
The braking of the vehicle, even in the worst case, is principally executed when the vehicle is
advancing straight ahead. During a turn, sudden braking is liable to cause a loss of traction
of the tires. Even in vehicles equipped with ABS, overturning of the vehicle cannot be pre-
vented if it is braked suddenly.
The ABS functions to prevent the tendency of the wheel to lock by controlling the brake fluid pres-
sure. However, if there is a tendency of the wheel to lock on a slippery road surface, due to engine
braking, the ABS may not be able to prevent the wheel from locking.

WARNING
The ABS controls only the tendency of the wheel to lock caused by applying the brakes. The
ABS cannot prevent wheel lock on slippery surfaces, such as ice, when it is caused by
engine braking, even if the ABS is operating.

Electronic ABS features
The Yamaha ABS (anti-lock brake system) has been developed with the most advanced electronic
technology.
The ABS control is processed with good response under various vehicle travel conditions.
The ABS also includes a highly developed self-diagnosis function. The ABS detects any problem
condition 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 ABS ECU for easy problem identifica-
tion and troubleshooting.
c. Side force
d. Slip ratio (%)
