Read the Owner’s Manual carefully
to become familiar with all controls.
If there is a control or function you
do not understand, ask your Yamaha
dealer.
EWA10271
WARNING
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an ac-
cident or injury.
EAU45310
TIPThis model is equipped with a lean
angle sensor to stop the engine in
case of a turnover. To start the en-
gine after a turnover, be sure to turn
the main switch to “OFF” and then to
“ON”. Failing to do so will prevent the
engine from starting even though the
engine will crank when pushing the
start switch.
EAUT1864
Starting the engine
ECA10250
NOTICESee page 5-3 for engine break-in
instructions prior to operating the
vehicle for the rst time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up.
See page 3-12 for more information.
1. Turn the key to “ON”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the
front or rear brake.
If the engine does not start, re-
lease the start switch, wait a few
seconds, and then try again.
Each starting attempt should be
as short as possible to preserve
the battery. Do not crank the en-
gine more than 5 seconds on any
one attempt. If the engine does
not start with the starter motor, try
using the kickstarter.
ECA11042
NOTICEFor maximum engine life, never ac-
celerate hard when the engine is
cold!

Acceleration and decelera-
tion
(a)(b)
The speed can be adjusted by open-
ing and closing the throttle. To in-
crease the speed, turn the throttle grip
in direction (a). To reduce the speed,
turn the throttle grip in direction (b).

Braking
EWA10300
WARNING
● Avoid braking hard or sud-
denly (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 diffi-
cult.● Ride slowly down a hill, as
braking downhill can be very
dif cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EAU16761
Starting offTIPBefore starting off, allow the engine to
warm up.
1. While pulling the rear brake lever
with your left hand and holding
the grab bar with your right hand,
push the scooter off the center-
stand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signals on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip
(on the right) in order to take off.
5. Switch the turn signals off.

Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:● Avoid high engine speeds during
acceleration.● Avoid high engine speeds with no
load on the engine.● Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod 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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for fi ve to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the
gears, but do not use full throttle at
any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000 km
(600 mi) of operation, the engine oil
must be changed and the oil strain-
er cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

WARNING
● Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.● Do not park on a slope or on
soft ground, otherwise the ve-
hicle may overturn, increasing
the risk of a fuel leak and re.● Do not park near grass or other
flammable materials which
might catch re.

PERIODIC MAINTENANCE AND ADJUSTMENT

PERIODIC MAINTENANCE AND ADJUSTMENT
EAUS1823
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most effi cient condition
possible. Safety is an obligation of
the vehicle owner/operator. The most
important points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However,
depending on the weather, terrain,
geographical location, and individual
use, the maintenance intervals may
need to be shortened.
EWA10321
WARNING
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle.
If you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15122
WARNING
Turn off the engine when perform-
ing maintenance unless otherwise
speci ed.● A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
res.● Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monox-
ide poisoning - possibly lead-
ing to death. See page 1-2 for
more information about carbon
monoxide.
EWA10330
WARNING
This scooter is designed for use
on paved roads only. If this scooter
is operated in abnormally dusty,
muddy or wet conditions, the air
lter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for proper
maintenance intervals.
EWA15460
WARNING
Brake discs, calipers, drums, and
linings can become very hot dur-
ing use. To avoid possible burns,
let brake components cool before
touching them.
EAU17302
Emission controls not only function
to ensure cleaner air, but are also
vital to proper engine operation and
maximum performance. In the follow-
ing periodic maintenance charts, the
services related to emissions control
are grouped separately. These serv-
ices require specialized data, knowl-
edge, and equipment. Maintenance,
replacement, or repair of the emission
control devices and systems may be
performed by any repair establishment
or individual that is certifi ed (if applica-
ble). Yamaha dealers are trained and
equipped to perform these particular
services.

TIP● The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.● From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).● Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.
