Safety information

1 engine exhaust. Deadly levels of car-
bon monoxide can collect rapidly and
you can quickly be overcome and un-
able to save yourself. Also, deadly lev-
els of carbon monoxide can linger for
hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution
of the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or acces-
sories to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to
minimize imbalance or instability.
Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the scooter be-
fore riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• Never attach any large or heavy
items to the handlebar, front
fork, or front fender. Such items
can create unstable handling or
a slow steering response.
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Maximum load:
181 kg (399 lb) (YP125RA)
185 kg (408 lb) (YP125R)

Indicator lights and warning
lights
EAU11032Turn signal indicator lights “ ”
and“”
Each indicator light will flash when its
corresponding turn signal lights are
flashing.
EAU11081High beam indicator light “ ”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11354Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
2.5 L (0.66 US gal, 0.55 Imp.gal). When
this occurs, refuel as soon as possible.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
EAU43024Engine trouble warning light “ ”
This warning light comes on if an elec-
trical circuit monitoring the engine is
not working correctly. If this occurs,
have a Yamaha dealer check the self-
diagnosis system.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
TIP
This warning light will come on when
switch is pushed, but this does not in-
dicate a malfunction.
EAUM3381ABS warning light “ ” (for ABS
models)
In normal operation, the ABS warning
light comes on when the key is turned
to “ON”, and goes off after traveling at
a speed of 10 km/h (6 mi/h) or higher.

3 The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 3-16 for an expla-
nation of the ABS.)
WARNING
EWA16041
If the ABS warning light does not go
off after traveling at a speed of 10
km/h (6 mi/h) or higher, or if the
warning light comes on or flashes
while riding, the brake system re-
verts to conventional braking. If ei-
ther of the above occurs, or if the
warning light does not come on at
all, use extra caution to avoid possi-
ble wheel lock during emergency
braking. Have a Yamaha dealer
check the brake system and electri-
cal circuits as soon as possible.
TIP
The ABS warning light may come on
while accelerating the engine with the
scooter on its centerstand, but this
does not indicate a malfunction.
EAU26879Immobilizer system indicator
light “ ”
When the key is turned to “OFF” and
30 seconds have passed, the indicator
light will start flashing indicating the im-
mobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.If the indicator light does not come on
initially when the key is turned to “ON”,
or if the indicator light remains on, have
a Yamaha dealer check the electrical
circuit.
The self-diagnosis device also detects
problems in the immobilizer system
circuits. (See page 3-13 for an explana-
tion of the self-diagnosis device.)

the oil trip value will reset to zero.
TIP
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must be
reset after the oil change for the next
periodic oil change to be indicated at
the correct time. To reset the oil
change indicator before the periodic oil
change interval has been reached, fol-
low the above procedure.
The electrical circuit of the indicator
can be checked according to the fol-
lowing procedure.

2. Check that the oil change indica-
tor comes on for a few seconds
and then goes off.
3. If the oil change indicator does not
come on, have a Yamaha dealer
check the electrical circuit.
V-belt replacement indicator “V-
Belt”
This indicator flashes every 18000 km
(10500 mi) when the V-belt needs to be
replaced.
After changing the V-belt, reset the V-
belt replacement indicator.
To reset the V-belt replacement indi-
cator
1. Turn the key to “ON”.
2. Push the “TRIP” button until “V-
Belt” (V-belt replacement tripme-
ter) is displayed in the odometer
and trip meter display. While “V-
Belt” is displayed, push the “RE-SET” button for 3 seconds. The V-
belt replacement tripmeter value
will flash.
3. Hold the “RESET” button pushed
for 15 to 20 seconds.
4. Release the “RESET” button, and
the V-belt trip value will reset to
zero.
TIP
If the V-belt is replaced before the indi-

This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the display will
indicate an error code.
If the display indicates any error codes,
note the code number, and then have a
Yamaha dealer check the vehicle.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with
changes in the weather and engine
load. If the top segment and coolant
temperature warning indicator flash,
stop the vehicle and let the engine
cool.NOTICE

Ignition circuit cut-off system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the side-
stand is up, but neither brake is
applied.
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-off system accord-
ing to the following procedure.
