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. 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 ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.

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.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test
all other accessories that may be avail-
able, you must personally be responsi-
ble for the proper selection, installationand use of non-Yamaha accessories.
Use extreme caution when selecting
and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.


Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
or cornering clearance, limit sus-
pension travel, steering travel or
control operation, or obscure lights
or reflectors.

Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution or aerody-
namic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.

Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodynamiceffects. Wind may attempt to lift
the scooter, or the scooter may
become unstable in cross
winds. These accessories may
also cause instability when
passing or being passed by
large vehicles.

Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.

Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
scooter’s electrical system an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas

GASOLINE IS HIGHLY FLAMMA-
BLE:

Always turn the engine off when
refueling.

Immobilizer system
This vehicle is equipped with an immo-
bilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the fol-
lowing.

a code re-registering key (with a
red bow)

two standard keys (with a black
bow) that can be re-registered with
new codes

a transponder (which is installed in
the code re-registering key)

an immobilizer unit

an ECU (Electronic Control Unit)

an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to
a Yamaha dealer to have them re-reg-
istered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
CAUTION:

ECA11821

DO NOT LOSE THE CODE
RE-REGISTERING KEY! CON-
TACT YOUR DEALER IMMEDI-
ATELY IF IT IS LOST! If the code
re-registering key is lost, regis-
tering new codes in the stan-
dard keys is impossible. The
standard keys can still be used
to start the vehicle, however if
code re-registering is required
(i.e., if a new standard key is
made or all keys are lost) the en-
tire immobilizer system must be
replaced. Therefore, it is highly
recommended to use either
standard key and keep the codere-registering key in a safe
place.

Do not submerse any key in wa-
ter.

Do not expose any key to exces-
sively high temperatures.

Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).

Do not place items that transmit
electrical signals close to any
key.

Do not place heavy items on any
key.

Do not grind any key or alter its
shape.

Do not disassemble the plastic
part of any key.

Do not put two keys of any im-
mobilizer system on the same
key ring.

Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle’s code re-registering key.

Keep other immobilizer system
keys away from the main switch

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.
EAU12993
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.

holding cable from the helmet holder
and the helmet, and then close the
seat.

mum load for the vehicle.


Do not carry along loosely
packed items, which can shift
during a ride.

Securely pack the heaviest
items close to the center of the
vehicle and distribute the
weight evenly on both sides.

Adjust the tire air pressure with
regard to the load.

Check the tire condition and air
pressure before each ride.
Tire inspection
The tires must be checked before eachride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
NOTE:

The tire tread depth limits may differ
from country to country. Always comply
with the local regulations.
Tire information
This model is equipped with tubeless
tires.
WARNING

EWA10470

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.

The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
