Rear brake lock lever
This vehicle is equipped with a rear
brake lock lever to prevent the rear
wheel from moving while stopped at
traffic signals, railroad crossings, etc.
To lock the rear wheel
Push the rear brake lock lever to the left
until it snaps into place.
To unlock the rear wheel
Push the rear brake lock lever back to
the original position.
NOTE:
Be sure to check that the rear
wheel does not move when therear brake lock lever is applied.
To provide secure locking of the
rear wheel, apply the rear brake le-
ver first before moving the rear
brake lock lever to the left.
WARNING
EWA12361
Never move the rear brake lock lever
to the left while the vehicle is mov-
ing, otherwise loss of control or an
accident may result. Make sure that
the vehicle is stopped before mov-
ing the rear brake lock lever to the
left.
EAU12991
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. The ABS
securely controls wheel lockup during
emergency braking on changing road
surfaces and under various weather
conditions, thereby maximizing tire ad-
hesion and performance while provid-
ing a smooth braking action. The ABS
is monitored by an ECU (Electronic
Control Unit), which will have recourse
to manual braking if a malfunction oc-
curs.
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 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 required, so
please consult your Yamaha deal-
er when performing this test.

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.
EAU33520
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.

Catalytic converter
This model is equipped with a catalytic
converter 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.

There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect thebrake system.
WARNING
EWA14211
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re-
sult in loss of control and an acci-
dent.
EAU33473
Adjusting the rear brake lock
lever cable
Rear brake lock lever cable adjustment
may be required if the rear brake lock
lever does not hold properly. When the
rear brake lock lever is not in use, the
rear brake lock lever cable length
should measure 45 mm to 47 mm (1.77
in to 1.85 in) at the rear brake caliper.
Periodically check the rear brake lock
lever cable length and, if necessary,
adjust it as follows.
To increase the rear brake lock lever
cable length, turn the adjusting nut at
the rear brake caliper in direction (a).

Checking the front and rear
brake pads
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22430
Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the wearindicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22493
Rear brake pads
1. Remove the rear brake caliper by
removing the bolts.
2. Check each rear brake pad for
damage and measure the lining
thickness. If a brake pad is dam-
aged or if the lining thickness is
less than 0.8 mm (0.03 in), have a
Yamaha dealer replace the brake
pads as a set.
3. Install the rear brake caliper by in-

stalling the bolts, then tightening
them to the specified torque.
CAUTION:

Do not apply the rear brake or rear
brake lock after the brake caliper
has been removed, otherwise the
brake caliper piston will be forced
out.
EAU22710
Checking the brake fluid level
Front brake
Rear brake
Insufficient brake fluid may allow air toenter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
Be careful that water or dust does
not enter the brake fluid reservoir
