SAFETY INFORMATION
Aftermarket Parts, Accessories,
and Modi cations
While you may fi nd aftermarket prod-
ucts 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 modifi cations
performed to your vehicle that change
any of the vehicle’s design or opera-
tion characteristics can put you and
others at greater risk of serious injury
or death. You are responsible for inju-
ries related to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under
“Loading” when mounting accesso-
ries.●
Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully inspect the accessory before
using it to make sure that it does
not in any way reduce ground
clearance or cornering clearance,
limit suspension travel, steering travel or control operation, or ob-
scure lights or refl ectors.
• Accessories fitted to the han-
dlebar or the front fork area can
create instability due to improp-
er weight distribution or aerody-
namic 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 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.
• Certain accessories can dis-
place 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 acces-sories are not recommended.
●
Use caution when adding electri-
cal accessories. If electrical ac-
cessories 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.
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 handling,
braking, and comfort. Other tires,
rims, sizes, and combinations may not
be appropriate. Refer to page 6-17 for
tire specifications and more informa-
tion on replacing your tires.
Transporting the Scooter
Be sure to observe following instruc-
tions before transporting the scooter
in another vehicle.
●
Remove all loose items from the
scooter.
●
Point the front wheel straight
ahead on the trailer or in the truck
