ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control system, which acts on the
front and rear brakes independently.
The ABS securely controls wheel loc-
kup during emergency braking on
changing road surfaces and under
various weather conditions, thereby
maximizing tire adhesion and perfor-
mance while providing a smooth bra-
king action. The ABS is monitored by
an ECU, which will have recourse to
manual braking if a malfunction
occurs.
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance
may be longer with than wit-
hout the ABS. Therefore,
always keep a sufficient distan-
ce 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” noi-
se can be heard from the front of
the vehicle, and if either brake
lever is even slightly applied, a
vibration can be felt at the lever,
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 levers, but this
does not indicate a malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsating at the brake levers
when the ABS is operating.
However, special tools are requi-
red, so please consult your
Yamaha dealer when performing
this test.WARNING

the front and rear wheel hubs,
otherwise the magnetic rotors
equipped in the wheel hubs may be
damaged, resulting in improper
performance of the ABS system.

Adjusting the shock
absorber assemblies
EWA10210
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Each shock absorber assembly is
equipped with a spring preload adjus-
ting ring.
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock
absorber assembly in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring on each shock absor-
ber assembly in direction (b).
Align the appropriate notch in the
adjusting ring with the position
indicator on the shock absorber.
Use the spring preload adjusting
tool included in the owner’s tool
kit to make this adjustment.

Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.

Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-

TIP
This model is equipped with a lean
angle sensor to stop the engine in
case of a turnover. In this case, the
multi-function display indicates error
code 30, but this is not a malfunction.
Turn the key to “OFF” and then to
“ON” to clear the error code. Failing
to do so will prevent the engine from
starting even though the engine will
crank when pushing the start switch.

Starting the engine
ECA10250
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up.
See page 3-22 for more information.
1. Turn the key to “ON”.

cator light and indicators should
come on for a few seconds, then

Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water will
significantly lower the boiling
point of the fluid and may result
in vapor lock, and dirt may clog
the ABS hydraulic unit valves.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.
EAU23112
Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.

Replacing the fuses
The fuse box, which contains the
fuses for the individual circuits, is
located behind cowling A. (See page
6-8).
TIP
The main fuse, which is in a different
and hard-to-reach location, must be
replaced by a Yamaha dealer.
If a fuse for the individual circuits is
blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensive
damage to the electrical sys-
tem and possibly a fire.
[EWA15131]
TIP
Fuse tongs and a bag containing spa-
re fuses are included in the owner’s
tool kit. Use the tongs to remove and
install a fuse.
