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 acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce. There-
fore, Yamaha can neither endorse nor
recommend the use of accessories not
sold by Yamaha or modifications not
specifically recommended by Yamaha,
even if sold and installed by a Yamaha
dealer.
Aftermarket Parts, Accessories, and
Modifications
While you may find aftermarket products
similar in design and quality to genuine
Yamaha accessories, recognize that
some aftermarket accessories or modi-
fications are not suitable because of
potential safety hazards to you or oth-
ers. Installing aftermarket products or
having other modifications performed toyour vehicle that change any of the
vehicle’s design or operation character-
istics 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 “Load-
ing” when mounting accessories.
●
Never 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.
Accessories fitted to the
handlebar or the front fork area
can create instability due to
improper 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 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
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.
●
Use caution when adding electrical
accessories. If electrical accesso-
ries exceed the capacity of the
scooter’s electrical system, an elec-
