ABS The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently. The ABS is
monitored by an ECU, which will have
recourse to manual braking if a mal-
function occurs.
WARNING
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance may
be longer with than without the
ABS. Therefore, always keep a
sufficient distance to the vehicle
ahead to match the riding
speed.
TIP
The ABS performs a self-diagno-
sis test for a few seconds each
time the vehicle first starts off after
the key was turned to “ON ”. During
this test, a “clicking ” noise can be
heard from under the seat, and if
the brake lever or brake pedal are even slightly applied, a vibration
can be felt at the lever and pedal,
but these do not indicate a mal-
function.
When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be felt
at the brake lever or brake pedal,
but this does not indicate a mal-
function.
This ABS has a test mode which
allows the owner to experience the
pulsating at the brake lever or
brake pedal when the ABS is oper-
ating. However, special tools are
required, so please consult your
Yamaha dealer when performing this test.
NOTICE
ECA16830
Keep any type of magnets (including
magnetic pick-up tools, magnetic
screwdrivers, etc.) away from the
front and rear wheel hubs; other-
wise, the magnetic rotors equipped
in the wheel hubs may be damaged, resulting in improper performance
of the ABS and the unified brake
system.
