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. Make
sure to distribute the weight as
evenly as possible on both sides
of the scooter to minimize imba-
lance 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.
●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 response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use onthis scooter. Since Yamaha cannot
test all other accessories that may be
available, you must personally be res-
ponsible for the proper selection, ins-
tallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.
Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
●Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully inspect the accessory befo-
re using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area,they must be as lightweight as
possible and should be kept to
a minimum.
• Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodyna-
mic effects. Wind may attempt
to lift the scooter, or the scoo-
ter may become unstable in
cross winds. These accesso-
ries may also cause instability
when passing or being passed
by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-
edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such
accessories are not recom-
mended.
●Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
