Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements before riding this motorcycle.
He or she should:
Obtain thorough instructions
from a competent source on all
aspects of motorcycle operation.
Observe the warnings and main-
tenance requirements in this
Owner’s Manual.
Obtain qualified training in safe
and proper riding techniques.
Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.
Safe Riding
Perform the pre-operation checkseach time you use the vehicle to
make sure it is in safe operating
condition. Failure to inspect or
maintain the vehicle properly
increases the possibility of an
accident or equipment damage.
See page 4-1 for a list of pre-ope-
ration checks.
This motorcycle is designed to
carry the operator and a passenger.
The failure of motorists to detect
and recognize motorcycles in
traffic is the predominating cause
of automobile/motorcycle acci-
dents. Many accidents have
been caused by an automobile
driver who did not see the
motorcycle. Making yourself
conspicuous appears to be very
effective in reducing the chance
of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since
intersections are the most
likely places for motorcycle
accidents to occur.• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current motorcycle licen-
se.
• Make sure that you are quali-
fied and that you only lend your
motorcycle to other qualified
operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your motorcycle
where there is no traffic until
you have become thoroughly
familiar with the motorcycle
and all of its controls.
Many accidents have been cau-
sed by error of the motorcycle
operator. A typical error made by
the operator is veering wide on a
turn due to excessive speed or
undercornering (insufficient lean
angle for the speed).

installed by a Yamaha dealer.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket pro-
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 motorcycle.
Carefully inspect the accessory
before using it to make sure that
it does not in any way reduceground 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 motorcycle due to aerody-
namic effects. Wind may
attempt to lift the motorcycle,
or the motorcycle 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 fre-edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such accesso-
ries are not recommended.
• Use caution when adding elec-
trical accessories. If electrical
accessories exceed the capa-
city of the motorcycle’s electri-
cal 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
motorcycle were designed to match
the performance capabilities and to
provide 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 information on replacing your
tires.
Transporting the Motorcycle
Be sure to observe following instruc-
tions before transporting the
motorcycle in another vehicle.

This shock absorber assembly
contains highly pressurized nitro-
gen gas. Read and understand the
following information before hand-
ling the shock absorber assembly.
Do not tamper with or attempt
to open the cylinder assembly.
Do not subject the shock
absorber assembly to an open
flame or other high heat sour-
ce. This may cause the unit to
explode due to excessive gas
pressure.
Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
Do not dispose of a damaged
or worn-out shock absorber
assembly yourself. Take the
shock absorber assembly to a
Yamaha dealer for any service.
EAU15303
Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See page 3-20 for an
explanation of the ignition circuit cut-
off system.)
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.

Matte color cautionECA15192
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use
before cleaning the vehicle.
Using a brush, harsh chemical pro-
ducts or cleaning compounds
when cleaning these parts will
scratch or damage their surface.
Wax also should not be applied to
any matte colored finished parts.
EAU26004
Care
While the open design of a motorcy-
cle reveals the attractiveness of the
technology, it also makes it more vul-
nerable. Rust and corrosion can
develop even if high-quality compo-
nents are used. A rusty exhaust pipe
may go unnoticed on a car, however,
it detracts from the overall appearan-
ce of a motorcycle. Frequent and pro-
per care does not only comply with
the terms of the warranty, but it will
also keep your motorcycle looking
good, extend its life and optimize its
performance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors, inclu-
ding the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and abrush, but never apply such pro-
ducts onto seals, gaskets, sproc-
kets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.
Cleaning
ECA10772
Avoid using strong acidic whe-
el cleaners, especially on spo-
ked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, tho-
roughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protec-
tion spray.
Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with
water to clean plastic. Howe-
ver, if the plastic parts cannot
be thoroughly cleaned with
