Hazard switch “r”
With the key in the “ON” or Fposition,
use this switch to turn on the hazard
lights (simultaneous flashing of all turn
signal lights).
The hazard lights are used in case of
an emergency or to warn other drivers
when your vehicle is stopped where it
might be a traffic hazard.
ECA10061CAUTION:
Do not use the hazard lights for an
extended length of time with the
engine not running, otherwise the
battery may discharge.
EAU12820
Clutch lever
1. Clutch lever
The clutch lever is located at the left
handlebar grip. To disengage the
clutch, pull the lever toward the han-
dlebar grip. To engage the clutch, re-
lease the lever. The lever should be
pulled rapidly and released slowly for
smooth clutch operation.
The clutch lever is equipped with a
clutch switch, which is part of the igni-
tion circuit cut-off system. (See page
3-17).

Shift pedal
1. Shift pedal
The shift pedal is located on the left
side of the engine and is used in com-
bination with the clutch lever when
shifting the gears of the 5-speed con-
stant-mesh transmission equipped on
this motorcycle.

WARNING0
The vehicle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been de-
signed to assist the operator in ful-
filling the responsibility of raising
the sidestand before starting off.
Therefore, check this system regu-
larly as described below and have
a Yamaha dealer repair it if it does
not function properly.

EAU15301
Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See further down for an expla-
nation of the ignition circuit cut-off sys-
tem.)

the following functions.
●It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
●It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the side-
stand is still down.
●It cuts the running engine when
the transmission is in gear and
the sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.
EWA10250
WARNING0

OPERATION AND IMPORTANT RIDING POINTS
EAU15950
EWA10270
WARNING0
●Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
●Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
●Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

EAUB1570
Starting the engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
●The transmission is in the neutral
position.
●The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EWA10290
WARNING0
●Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure de-
scribed on page 3-18.
●Never ride with the sidestand
down.
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “
I”.

ECAB0070CAUTION:
The following warning lights and in-
dicator lights should come on for a
few seconds, then go off.
●Neutral indicator light
●Turn signal indicator light
●High beam indicator light
●Engine trouble warning light
●Coolant temperature warning
light
●Immobilizer system indicator
light
If a warning or indicator light does
not go off, see page 3-3 for the cor-
responding warning and indicator
light circuit check.
2. Shift the transmission into the neutral position.
NOTE:
When the transmission is in the neu-
tral position, the neutral indicator light
should be on, otherwise have a Yama-
ha dealer check the electrical circuit.

OPERATION AND IMPORTANT RIDING POINTS
3. Start the engine by pushing thestart switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt.
ECA11040CAUTION:
For maximum engine life, never ac-
celerate hard when the engine is
cold!
NOTE:
The engine is warm when it quickly re-
sponds to the throttle.
EAU16671
Shifting
1. Shift pedal
N. Neutral position
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the il-
lustration.
NOTE:
To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.

ECA10260CAUTION:
●Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long
distances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
●Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Periodic maintenance and lubrication chart
NOTE:● The annual checks must be performed every year, except if a kilometer-based maintenance is performed in-
stead.
●From 50000 km, repeat the maintenance intervals starting from 10000 km.
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and tech-
nical skills.

Coolant
The coolant level should be checked
before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
EAU20252
To check the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.
NOTE:
●The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
●Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the coolant reservoir.
ECA11620CAUTION:
● In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a
higher quality than specified. In
addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
● Make sure that no foreign ma-
terial enters the crankcase.
14. Start the engine, and then let it idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the en-
gine off and check for the cause.
15. Turn the engine off, and then check the oil level and correct it if
necessary.
16. Install the engine guard by in- stalling the screws.
NOTE:
Be sure to wipe off spilled oil on any
parts after the engine and exhaust
system have cooled down.
Recommended engine oil:See page 8-1.
Oil quantity: Without oil filter element
replacement:2.50 L (2.64 US qt) (2.19 Imp.qt)
With oil filter element replacement: 2.60 L (2.73 US qt) (2.26 Imp.qt)
ECAM1060CAUTION:
The engine oil tank must be filled in
2 steps. First, fill the engine oil tank
with 1.90 L (2.0 US qt) (1.67 Imp.qt)
of the recommended engine oil.
Then, start the engine, race it 5 or 6
times, turn it off, and then add the
remainder of the engine oil.
