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 (Electronic Con-
trol Unit), which will have recourse to
manual braking if a malfunction 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 ridingspeed.
NOTE:
The ABS performs a self-diagno-
sis test for a few seconds each
time the vehicle first starts off after
the main switch was turned on.
During this test, a “clicking” noise
can be heard from under the seat,
and if the brake lever or brake ped-al are even slightly applied, a vi-
bration can be felt at the lever and
pedal, but these do not indicate a
malfunction.
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 performingthis test.
CAUTION:
ECA16120
Keep any type of magnets (including
magnetic pick-up tools, magnetic
screwdrivers, etc.) away from the
front and rear wheel hubs, otherwise
the magnetic rotors equipped in the
wheel hubs may be damaged, result-
ing in improper performance of theABS system.
