Brake lever
The brake lever is located at the right
handlebar grip. To apply the front
brake, pull the lever toward the handle-
bar grip.
The brake lever is equipped with a po-
sition adjusting dial. To adjust the dis-
tance between the brake lever and the
handlebar grip, turn the adjusting dial
while holding the lever pushed away
from the handlebar grip. Make sure that
the appropriate setting on the adjustingdial is aligned with the “” mark on the
brake lever.

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 vehi-
cle ahead to match the riding
speed.
NOTE:


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 whichallows 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.

NOTE:

The fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING

EWA11090
Make sure that the fuel tank cap is
properly closed before riding.
EAU13211
Fuel
Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.
WARNING

EWA10880

Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.

Avoid spilling fuel on the hot en-
gine.
CAUTION:

ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, sincefuel may deteriorate painted surfac-
es or plastic parts.
EAU13320
CAUTION:

ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

Fuel tank breather hose
Before operating the motorcycle:

Check the fuel tank breather hose
connection.

Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.

Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.
EAU13442
Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING

EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
CAUTION:

ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

Do not allow the engine to idle
too long.
EAU13861
Seat
To remove the seat
Insert the key into the seat lock, turn it
counterclockwise, and then pull the
seat off.
To install the seat
Insert the projections on the front of the
seat into the seat holders, push the rear
of the seat down to lock it in place, and
then remove the key.

Storage compartment
This storage compartment is designed
to hold an optional genuine Yamaha
CYCLELOK. (Other locks may not fit.)
When placing a CYCLELOK in the stor-
age compartment, securely fasten it
with the straps. When the CYCLELOK
is not in the storage compartment, be
sure to secure the straps to prevent los-
ing them.
When storing the owner’s manual or
other documents in the storage com-
partment, be sure to wrap them in a
plastic bag so that they will not get wet.When washing the motorcycle, be
careful not to let any water enter the
storage compartment.

Adjusting the front fork
This front fork is equipped with spring
preload adjusting bolts and damping
force adjusting screws.
WARNING

EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften thesuspension, turn the adjusting bolt on
each fork leg in direction (b).
NOTE:

Align the appropriate groove on the ad-
justing mechanism with the top of the
front fork cap bolt.
Damping force
1. Turn the adjusting screw on each
fork leg in direction (a) until the
screw moves almost a 1/2 turn
without clicking.
2. Continue turning the adjusting
screw in direction (a) until it clicks.
This is the minimum setting.
3. To increase the damping force,
continue turning the adjusting
screw in direction (a). The third
click after the minimum setting is
the maximum setting. If the adjust-
ing screw is turned further in direc-
tion (a), it will move half a turn
before returning to the minimum
setting.

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
CAUTION:

ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum or
minimum settings.

To increase the spring preload andthereby harden the suspension, turn
the adjusting ring in direction (a). To de-
crease the spring preload and thereby
soften the suspension, turn the adjust-
ing ring in direction (b).

(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).
Compression damping force
To increase the compression dampingforce and thereby harden the compres-
sion damping, turn the adjusting knob
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn
the adjusting knob in direction (b).
NOTE:

Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.
WARNING

EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.

Do not tamper with or attempt to
open the gas cylinder.

Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.

Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.

Always have a Yamaha dealer
service the shock absorber.
