Q QQ Q
Q SAFETY INFORMATIONLoading
The total weight of the operator, passen-
ger, accessories and cargo must not ex-
ceed the maximum load limit of 170 kg
(374 lb). When loading within this weight
limit, keep the following in mind:
8Cargo and accessory weight should
be kept as low and close to the
scooter as possible. Make sure to
distribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance or
instability.
8Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before riding.
Check accessory mounts and
cargo restraints frequently.
8Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can cre-
ate unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test
all other accessories that may be avail-
able, you must personally be responsible
for the proper selection, installation and
use of non-Yamaha accessories. Use
extreme caution when selecting and in-
stalling any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.
8Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before us-
ing it to make sure that it does not
in any way reduce ground clear-
ance or cornering clearance, limit
suspension travel, steering travel
or control operation, or obscure
lights or reflectors.
9Accessories fitted to the
handlebar or the front fork area
can create instability due to
improper weight distribution or
aerodynamic changes. Ifaccessories are added to the
handlebar or front fork area,
they must be as lightweight as
possible and should be kept to
a minimum.
9Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodynamic
effects. Wind may attempt to
lift the scooter, or the scooter
may become unstable in cross
winds. These accessories may
also cause instability when
passing or being passed by
large vehicles.
9Certain accessories can
displace the operator from his
or her normal riding position.
This improper position limits
the freedom of movement of
the operator and may limit
control ability, therefore, such
accessories are not recom-
mended.
8Use caution when adding electrical
accessories. If electrical accesso-
ries exceed the capacity of the
scooter’s electrical system an elec-

Q SAFETY INFORMATION
tric failure could result, which could
cause a dangerous loss of lights or
engine power.
Gasoline and exhaust gas
8GASOLINE IS HIGHLY FLAM-
MABLE:
9Always turn the engine off
when refueling.
9Take care not to spill any
gasoline on the engine or
exhaust system when refueling.
9Never refuel while smoking or
in the vicinity of an open flame.
8Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of con-
sciousness and death within a
short time. Always operate your
scooter in an area that has adequate
ventilation.
8Always turn the engine off before
leaving the scooter unattended and
remove the key from the main
switch. When parking the scooter,
note the following:
9The engine and exhaustsystem may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.
9Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
9Do not park the scooter near a
flammable source (e.g., a
kerosene heater, or near an
open flame), otherwise it could
catch fire.
8If you should swallow any gasoline,
inhale a lot of gasoline vapor, or
allow gasoline to get into your eyes,
see your doctor immediately. If any
gasoline spills on your skin or cloth-
ing, immediately wash the affected
area with soap and water and
change your clothes.

OPERATION AND IMPORTANT RIDING POINTS
EAU16830
Engine break-inThere 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 follow-
ing 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 themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided.
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
8Avoid high engine speeds during
acceleration.
8Avoid high engine speeds with no
load on the engine.
8Turn 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 crossings).
EAU16950
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 five 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.
ECA10350
cCAfter 1000 km (600 mi) of operation,
the engine oil must be changed and
the oil strainer cleaned.1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
cCIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
