SAFETY INFORMATION

1


Do not run engine in poorly venti-
lated 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
motorcycle can adversely affect stabili-
ty and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use ex-
treme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
Here, along with the information about
accessories below, are some general
guidelines to follow if loading cargo to
your motorcycle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.When loading within this weight limit,
keep the following in mind:


Cargo and accessory weight
should be kept as low and close to
the motorcycle as possible. Se-
curely pack your heaviest items as
close to the center of the vehicle as
possible and make sure to distrib-
ute the weight as evenly as possi-
ble on both sides of the motorcycle
to minimize imbalance or instabili-
ty.


Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad-
justable 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. Theseitems, including such cargo as
sleeping bags, duffel bags, or
tents, can create unstable han-
dling 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 acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Maximum load:
196 kg (432 lb)

1 Aftermarket Parts, Accessories, and
Modifications
While you may find aftermarket prod-
ucts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accessories
or modifications are not suitable be-
cause of potential safety hazards to you
or others. Installing aftermarket prod-
ucts or having other modifications per-
formed 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 “Load-
ing” when mounting accessories.


Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. 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 reflectors.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
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 motorcycle due to aerody-
namic effects. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become un-
stable in cross winds. These ac-
cessories 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 free-
dom of movement of the opera-tor and may limit control ability,
therefore, such accessories are
not recommended.


Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
motorcycle’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
motorcycle were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, siz-
es, and combinations may not be
appropriate. Refer to page 6-13 for tire
specifications and more information on
replacing your tires.
