Anti-lock brake system (ABS)This model’s ABS features a dual elec-
tronic control system, which acts on
the front and rear brakes independent-
ly.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahea d to match the
ri din g speed even with ABS.
The ABS performs best with
lon g b rakin g d istances.
On certain surfaces, such as
rou gh or g ravel roa ds, the b rak-
in g d istance may be lon ger with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIP The ABS performs a self-diagno-
sis test each time the vehicle is
turned on and travels at a speed of
10 km/h (6 mi/h) or higher. During
this test, a clicking noise can be
heard and if either brake lever is
even slightly applied, a vibration
can be felt at the lever, but this
does not indicate a malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. How-
ever, special tools are required, so
please consult your Yamaha deal-
er.NOTICE
ECA20100
Be careful not to d amage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
