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.
