Engine trouble warning light “ ”
This warning light flashes or stays on if
an electrical circuit monitoring the en-
gine is not working correctly. If this oc-
curs, have a Yamaha dealer check the
self-diagnosis system.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
EAU58530
ABS warning light “ ” (for ABS
models)
In normal operation, the ABS warning
light comes on when the key is turned
to “ON”, and goes off after traveling at
a speed of 10 km/h (6 mi/h) or higher.
If the ABS warning light:
does not come on when the key is
turned to “ON”
comes on or flashes while ridingdoes not go off after traveling at a
speed of 10 km/h (6 mi/h) or high-
er
The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 3-14 for an expla-
nation of the ABS.)
WARNING
EWA16041
If the ABS warning light does not go
off after traveling at a speed of 10
km/h (6 mi/h) or higher, or if the
warning light comes on or flashes
while riding, the brake system re-
verts to conventional braking. If ei-
ther of the above occurs, or if the
warning light does not come on at
all, use extra caution to avoid possi-
ble wheel lock during emergency
braking. Have a Yamaha dealer
check the brake system and electri-
cal circuits as soon as possible.
EAUM3440
Tachometer high-rpm warning light
This light flashes at 9500 r/min to warn
you that the engine speed is about to
enter the high-rpm zone. Once the en-gine speed reaches 10000 r/min, this
light will come on to warn you that it is
necessary to shift up to avoid engine
damage.
To activate or deactivate the tachome-
ter high-rpm warning light, hold the
“INFO” button pushed, turn the key to
“ON”, and when the tachometer high-
rpm warning light starts flashing, press
the “SELECT” button.
TIPWhen activating or deactivating the
warning light the function, after press-

come on to indicate that the function is
activated or the light will go off to indi-
cate that the function is deactivated.

Brake pedalThe brake pedal is located on the right
side of the motorcycle. To apply the
rear brake, press down on the brake
pedal.
EAU60021
ABS (for ABS models)The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake lever or brake ped-
al. In this situation, continue to apply
the brakes and let the ABS work; do
not “pump” the brakes as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer 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 first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from the
hydraulic control unit, and if the
brake lever or brake pedal is even
slightly applied, a vibration can be
felt at the lever and pedal, but
these do not indicate a malfunc-
tion.
This ABS has a test mode which
allows the owner to experience
the pulsation at the brake lever or
brake pedal when the ABS is op-
erating. However, special tools are
required, so please consult your
Yamaha dealer.NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.

Checking the front brake lever
free playThe brake lever free play should mea-
sure 2.0–5.0 mm (0.08–0.20 in) as
shown. Periodically check the brake le-
ver free play and, if necessary, have a
Yamaha dealer check the brake sys-
tem.
WARNING
EWA10642
An incorrect brake lever free play in-
dicates a hazardous condition in the
brake system. Do not operate the
vehicle until the brake system has
been checked or repaired by a
Yamaha dealer.
EAUM1354
Adjusting the brake pedal free
playThe brake pedal free play should mea-
sure 3.5–4.5 mm (0.14–0.18 in) as
shown. Periodically check the brake
pedal free play and, if necessary, have
a Yamaha dealer adjust it.
WARNING
EWAM1031
An incorrect brake pedal free play
indicates a hazardous condition in
the brake system. Do not operate
the motorcycle until the brake sys-
tem has been checked or repaired
by a Yamaha dealer.

Brake light switchesFor ABS models
The brake light, which is activated by
the brake pedal and brake lever,
should come on just before braking
takes effect. If necessary, adjust the
rear brake light switch as follows, but
the front brake light switch should be
adjusted by a Yamaha dealer.
Turn the rear brake light switch adjust-
ing nut while holding the rear brake
light switch in place. To make the
brake light come on earlier, turn the ad-

For non-ABS models
The brake light, which is activated by
the brake pedal and brake lever,
should come on just before braking
takes effect. If necessary, have a
Yamaha dealer check the brake light
switches.
EAU22393
Checking the front and rear
brake padsThe front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22421
Front brake pads
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wearindicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22501
Rear brake pads
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 1.5 mm (0.06 in),
have a Yamaha dealer replace the
brake pads as a set.
