1 Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to pro-
vide the best combination of handling,
braking, and comfort. Other tires, rims,
sizes, and combinations may not be
appropriate. Refer to page 7-18 for tire
specifications and more information on
replacing your tires.
Transporting the Scooter
Be sure to observe following instruc-
tions before transporting the scooter in
another vehicle.
Remove all loose items from the
scooter.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
Secure the scooter with tie-downs
or suitable straps that are at-
tached to solid parts of the scoot-
er, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the
scooter will not bounce exces-
sively during transport.
EAU57600
Further safe-riding points
Be sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
The brake pads or linings could
get wet when you wash the scoot-
er. After washing the scooter,
check the brakes before riding.
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a brightly colored jacket.
Do not carry too much luggage on
the scooter. An overloaded scoot-
er is unstable. Use a strong cord
to secure any luggage to the carri-
er (if equipped). A loose load will
affect the stability of the scooter
and could divert your attention
from the road. (See page 1-3.)

ABS
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.
The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIP
The ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the main switch is
turned to “ON” and the vehicle has
traveled at a speed of 10 km/h (6
mi/h) or higher. During this test, a
“clicking” noise can be heard from
the front of the vehicle, and if ei-
ther brake lever is even slightly ap-
plied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.

Ignition circuit cut-off system
The ignition circuit cut-off system
works with the sidestand switch and
brake light switches. It has the follow-
ing functions.
It prevents the engine from start-
ing when the sidestand is down.
It prevents the engine from start-
ing if the brakes are not applied.
It will stop the running engine if the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.

Braking
WARNING
EWA10301
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.Front

the area off with water, immedi-
ately dry it, and then apply a cor-
rosion protection spray.
Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with wa-
ter to clean plastic. However, if
the plastic parts cannot be thor-
oughly cleaned with water, di-
luted mild detergent with water
may be used. Be sure to rinse
off any detergent residue using
plenty of water, as it is harmful
to plastic parts.
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake fluid,
antifreeze or electrolyte.
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaningcompounds for plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the wind-
shield is scratched, use a quality
plastic polishing compound
af-
ter washing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea, or
on salt-sprayed roads
Since sea salt or salt sprayed on roads
during winter are extremely corrosive
in combination with water, carry out
the following steps after each ride in
the rain, near the sea, or on salt-
sprayed roads.
TIP
Salt sprayed on roads in the winter
may remain well into spring.
1. Clean the scooter with cold water
and a mild detergent after the en-
gine has cooled down. NOTICE:
Do not use warm water since it
increases the corrosive action
of the salt.
[ECA10792]
2. Apply a corrosion protection spray
on all metal, including chrome-
and nickel-plated, surfaces to pre-
vent corrosion.

8Cleaning the windshield
Avoid using any alkaline or strong acid
cleaner, gasoline, brake fluid, or any
other solvent. Clean the windshield
with a cloth or sponge dampened with
a neutral detergent, and after cleaning,
thoroughly wash it off with water. For
additional cleaning, use Yamaha Wind-
shield Cleaner or other quality cleaner.
Some cleaning compounds for plastics
may leave scratches on surfaces of the
windshield. Before using them, make a
test by polishing an area which does
not affect your visibility.
After cleaning
1. Dry the scooter with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
4. Use spray oil as a universal clean-
er to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely be-
fore storing or covering it.
WARNING
EWA10943
Contaminants on the brakes or tires
can cause loss of control.Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires with
warm water and a mild deter-
gent.
Before operating the scooter
test its braking performance
and cornering behavior.
NOTICE
ECAU0022
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
Never apply oil or wax to any
rubber parts, plastic parts or
headlight, taillight and meter
lenses, but treat them with a
suitable care product.
Avoid using abrasive polishing
compounds as they will wear
away the paint.
TIP
Consult a Yamaha dealer for ad-
vice on what products to use.
Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from the
lens.
