SAFETY INFORMATION●
Do not run engine in poorly ven-
tilated or partially enclosed areas
such as barns, garages, or car-
ports.
●
Do not run engine outdoors
where engine exhaust can be
drawn into a building through
openings such as windows and
doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution
of the scooter is changed. To avoid
the possibility of an accident, use ex-
treme caution when adding cargo or
accessories to your scooter. Use extra
care when riding a scooter that has
added cargo or accessories. Here,
along with the information about ac-
cessories below, are some general
guidelines to follow if loading cargo to
your scooter:
The total weight of the operator,
passenger, accessories and cargo
must not exceed the maximum load
limit. Operation of an overloaded
vehicle could cause an accident.
Maximum load:
179 kg (395 lb)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. Se-
curely pack your heaviest items
as close to the center of the ve-
hicle as possible and 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
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspen-
sion for your load (suspension-
adjustable models only), and
check the condition and pres-
sure of your tires.
• 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 re-
sponse.
●
This vehicle is not designed to
pull a trailer or to be attached
to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail-
able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and ac-
cessories or offer other modifications
for Yamaha vehicles. Yamaha is not
in a position to test the products that
these aftermarket companies pro-
duce. Therefore, Yamaha can neither
endorse nor recommend the use of
accessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.

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.
EAUT3540
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.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000
km (600 mi) of operation, be sure
to change the engine oil and final
transmission oil, and to clean the
oil strainer.
[ECA16501]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
