Fuel tank overflow hose
Before operating the vehicle:
Check the fuel tank overflow hose
connection and routing.
Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.
Make sure that the fuel tank over-
flow hose is not blocked, and clean
it if necessary.
EAU13434
Catalytic converter
This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.

Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cu t-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-
tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU66771
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-of f system according
to the following procedure.

Operation and important riding points
EAU15952
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.
WARNING
EWA10272
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU77750
TIP
This model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the engine trouble warning
light will come on, but this is not a
malfunction. Turn the vehicle pow-
er off to extinguish the warning
light. Failing to do so will prevent
the engine from starting even
though the engine will crank when
pushing the start switch.
an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start switch
to restart the engine.

Starting the engine
NOTICE
ECA10251
See page 7-5 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up. (See page 5-29.) 1. With the smart key turned on, ap- proach the vehicle.
2. Push the “ON/ ” switch.
Upon authentication of the smart
key, the beeper will sound twice
and the centerstand and steering
locks (if applied) will be released.
All indicator and warning lights
should come on briefly and then go
off.
The ABS warning light should
come on when the power of the ve-
hicle is turned on, and go off once
the vehicle reaches a traveling
speed of 10 km/h (6 mi/h) or high-
er.
NOTICE
ECA22510
If a warning or indicator light does
not work as described above, see
page 5-2 for the corresponding warning and indicator light circuit
check.
3. Close the throttle completely.
4. Start the engine by pushing the “ON/ ” switch while applying the
front or rear brake.
If the engine does not start within 5
seconds of pressing the “ON/ ”
switch, wait 10 seconds before
pressing the switch again to allow
the battery voltage to restore.
NOTICE

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16842
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU36532
0–1000 km (0–600 mi)
Avoid prolonged operation above 5100
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed, and the oil filter car-
tridge or element replaced.
[ECA11283]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6100
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

Parking
When parking, turn the vehicle power
off and then the smart key off.
When leaving the vehicle, make sure
you apply the steering lock and center-
stand lock. Take the smart key with
you. It is recommended that you turn
the smart key off.
WARNING
EWA10312
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
Do not park near grass or other
flammable materials which
might catch fire.
TIP
Even when the vehicle is parked in a lo-
cation partitioned by a fence or the
glass window of a shop, if the smart key
is within operating range, other people
will be able to start the engine and op-
erate the vehicle. Please turn the smart
key off when leaving the vehicle. (See
page 3-5.)

Periodic maintenance and adjustment
EAU17246
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10322
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15123
Turn off the engine when performing
maintenance unless otherwise
specified.
A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to death. See page 1-2 for more in-
formation about carbon monox-
ide.
WARNING
EWA15461
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.
