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 ac-
cessories 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.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 accesso-
ries or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifications
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 “Load-
ing” when mounting accessories.
Never install accessories or carry
cargo that would impair the per-
formance of your motorcycle.
Carefully 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 opera-
tion, or obscure lights or reflec-
tors.
• 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 motorcycle due to aerody-
namic effects. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become
unstable in cross winds. These
accessories may also cause in-
stability 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

1operator and may limit control
ability, therefore, such accesso-
ries are not recommended.
Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle’s electrical sys-
tem, an electric failure could re-
sult, 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 han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
6-15 for tire specifications and more in-
formation on replacing your tires.
Transporting the Motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.
Remove all loose items from the
motorcycle.Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
Shift the transmission in gear (for
models with a manual transmis-
sion).
Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce exces-
sively during transport.

Multi-function meter unit
WARNING
EWA12423
Be sure to stop the vehicle before
making any setting changes to the
multi-function meter unit. Changingsettings while riding can distract the
operator and increase the risk of an
accident.
The multi-function meter unit is
equipped with the following:
a speedometer
a tachometer
a clock
a fuel meter
a coolant temperature meter
a transmission gear display
a multi-function display
a shift timing indicator light
a self-diagnosis deviceTIPBe sure to turn the key to Ž before

except for setting the shift timing indi-
cator light control mode.Speedometer
The speedometer shows the vehicle’s
traveling speed.Tachometer
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ ”, the ta-
chometer will sweep across the r/min
range and then return to zero r/min in
order to test the electrical circuit.

The fuel meter indicates the amount of
fuel in the fuel tank.
When the key is turned to “ ”, the dis-
play segments of the fuel meter will
sweep once across the fuel level range
and then return to the current amount
in order to test the electrical circuit.
The display segments of the fuel meter
disappear towards “E” (Empty) as the
fuel level decreases. When the last
segment starts flashing, refuel as soon
as possible.
TIPThis fuel meter is equipped with a self-
diagnosis system. If a problem is de-
tected in the electrical circuit, the fol-lowing cycle is repeated until the
malfunction is corrected: fuel level seg-
ments flash eight times, then go off for
approximately three seconds. If this
occurs, have a Yamaha dealer check
the electrical circuit.
Coolant temperature meter
The coolant temperature meter indi-
cates the temperature of the coolant.
When the key is turned to “ ”, the dis-
play segments of the digital coolant
temperature gauge will sweep once
across the temperature range and then
return to “C” in order to test the electri-
cal circuit.
