ducts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifica-
tions performed to your vehicle that
change any of the vehicle’s design or
operation characteristics can put you
and others at greater risk of serious
injury or death. You are responsible
for injuries related to changes in the
vehicle.
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 acces-
sories are not recommended. Use caution when adding elec-
trical accessories. If electrical
accessories exceed the capa-
city of the scooter’s electrical
system, an electric failure
could result, which could cau-
se a dangerous loss of lights or
engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to pro-
vide the best combination of hand-
ling, braking, and comfort. Other tires,
rims, sizes, and combinations may
not be appropriate. Refer to page
6-18 for tire specifications and more
information on replacing your tires.
EWA15470
Be sure to observe following ins-
tructions before transporting the
scooter in another vehicle.
Remove all loose items from
the scooter.
