14 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 attached
to solid parts of the scooter, such
as the frame or upper front fork tri-
ple clamp (and not, for example, to
rubber-mounted handlebars or
turn signals, or parts that could
break). Choose the location 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 excessive-
ly 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 cor-
ner or turn. Once you have com-
pleted 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 scooter.
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 carrier
(if equipped). A loose load will af-
fect the stability of the scooter and
could divert your attention from the
road. (See page 1-3.)

Adjusting the rear brake lock
cable
Periodically check the rear brake lock
cable length and adjust if necessary. 1. Release the rear brake lock lever.
2. To increase the rear brake lock ca- ble length, turn the adjusting nut at
the rear brake caliper in direction
(a). To decrease the rear brake
lock cable length, turn the adjust-
ing nut in direction (b).
3. Confirm that the rear brake lock le- ver (page 5-18) functions properly
and that the rear wheel rotates
freely when unlocked.
WARNING
EWA20290
If proper adjustment cannot be ob-
tained as described, have a Yamaha
dealer make this adjustment.
EAU52293
Checking the rear brake lock
The rear brake lock must be checked at
the intervals specified in the periodic
maintenance and lubrication chart.1. Adjust the rear brake lock cable.
2. Apply the rear brake lock, and then try to push the vehicle to confirm
that the rear brake lock functions
properly.
3. The rear brake lock caliper is pro- vided with a wear indicator, which
allows you to check the rear brake
lock pads. To check the rear brake
lock pads, check the position of the
indicator when the rear brake lock
lever is applied. If the indicator has
passed the wear indicator groove,
have a Yamaha dealer check the
rear brake lock.
4. Make sure that there are no tears or cracks on the rubber boot.

Checking the fr ont and rear
brake pads
Front brake
Rear brake
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart. Each brake pad is
provided with a wear indicator, which
allows you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the position of the wear indicator
while applying the brake. If a brake pad
has worn to the point that the wear indi-
cator almost touches the brake disc,
have a Yamaha dealer replace the
brake pads as a set.
EAU22583
Checking the brake fluid level
Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the res-
ervoir in an upright position. Replenish
the brake fluid if necessary.
NOTICE
ECA17641
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up spilled fluid immediately.

A low brake fluid level may indicate
worn brake pads or brake system
leakage; therefore, be sure to
check the brake pads for wear and
the brake system for leakage.
If the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.
WARNING
EWA15991
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
EAU22734
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
Brake seals: every 2 years
Brake hoses: every 4 years

chrome, aluminum, and stainless
steel parts. Often the thermally in-
duced discoloring of stainless steel
exhaust systems can be removed
through polishing.
4. Apply a corrosion protection spray on all metal parts including chrome
or nickel-plated surfaces.
WARNING! Do not apply
silicone or oil spray to seats,
hand grips, rubber foot pegs or
tire treads. Otherwise these
parts will become slippery,
which could cause loss of con-
trol. Thoroughly clean the sur-
faces of these parts before
operating the vehicle.
[EWA20650]
5. Treat rubber, vinyl, and unpaintedplastic parts with a suitable care
product.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces using a non-abrasive wax or use a detail
spray for motorcycles.
8. When finished cleaning, start the engine and let it idle for several
minutes to help dry any remaining
moisture.
9. If the headlight lens has fogged up, start the engine and turn on the
headlight to help remove the mois-
ture.
10. Let the vehicle dry completely be- fore storing or covering it.
NOTICE
ECA26320
Do not apply wax to rubber or
unpainted plastic parts.
Do not use abrasive polishing
compounds as they will wear away the paint.
Apply sprays and wax sparing-
ly. Wipe off excess afterwards.
WARNING
EWA20660
Contaminants left on the brakes or
tires can cause loss of control.
Make sure there is no lubricant
or wax on the brakes or tires.
If necessary, wash the tires with
warm water and a mild deter-
gent.
If necessary, clean the brake
discs and pads with brake
cleaner or acetone.
Before riding at higher speeds,
test the vehicle’s braking perfor-
mance and cornering behavior.
