EAU16780
Acceleration and
deceleration
The speed can be adjusted by ope-
ning and closing the throttle. To incre-
ase the speed, turn the throttle grip in
direction (a). To reduce the speed,
turn the throttle grip in direction (b).
EAU16791
Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EWA10300
s s
WARNING
Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road cons-
truction 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 bra-
king downhill can be very diffi-
cult.
EAU16830
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1000 km
(600 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUT1110
0~150 km (0~90 mi)
Avoid operation above 1/3 throttle.
Stop the engine and let it cool for 5 to
10 minutes after every hour of opera-
tion. Vary the speed of the scooterfrom time to time. Do not operate it at
one set throttle position.
150~500 km (90~300 mi)
Avoid prolonged operation above 1/2
throttle.
500~1000 km (300~600 mi)
Avoid cruising speeds in excess of
3/4 throttle.
ECAT1010
CAUTION
After 1000 km (600 mi) of operation,
be sure to replace the final gear oil.
1000 km (600 mi) and beyond
Avoid prolonged full throttle opera-
tion. Vary speeds occasionally.
ECA10270
CAUTION
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Parking
When parking, stop the engine, and
then remove the key from the main

Checking the front brake
fluid level
1. Minimum level
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.Observe these precautions:
When checking the fluid level,
make sure that the top of the
master cylinder is level by turning
the handlebars.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU22720
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the brake
master cylinder and caliper as well as
the brake hose replaced at the inter-
vals listed below or whenever they are
damaged or leaking.
Oil seals: Replace every two
years.
Brake hose: Replace every four
years.

WARNING
Securely support the motorcycle so

To check the operation
1. Place the motorcycle on a level
surface and hold it in an upright
position.2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.

have a Yamaha dealer check or
repair it.

Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-

raise the front wheel off the
ground.

Care
While the open design of a scooter
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go
unnoticed on a car, however, it
detracts from the overall appearance
of a scooter. Frequent and proper
care does not only comply with the
terms of the warranty, but it will also
keep your scooter looking good,
extend its life and optimize its perfor-
mance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors, inclu-
ding the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such pro-ducts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA10780
CAUTION
Avoid using strong acidic whe-
el cleaners, especially on spo-
ked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, tho-
roughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protec-
tion spray.
Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or spon-
ge with mild detergent and
water to clean plastic.
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 orthinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
Do not use high-pressure was-
hers or steam-jet cleaners sin-
ce they cause water seepage
and deterioration in the follo-
wing areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, 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 scrat-
ching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not lea-
ve any marks. If the windshield
is scratched, use a quality
plastic polishing compound
after washing.
