• 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 motorcycle accidents have
been caused by error of the
motorcycle operator. A typical
error made by the operator is
veering wide on a turn due to
EXCESSIVE SPEED or undercor-
nering (insufficient lean angle for
the speed).
• Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
The posture of the operator and
passenger is important for proper
control.• The operator should keep both
hands on the handlebar and
both feet on the operator foo-
trests during operation to
maintain control of the
motorcycle.
• The passenger should always
hold onto the operator, seat
strap, or grab bar, if equipped,
with both hands and keep both
feet on the passenger foo-
trests.
• Never carry a passenger
unless he or she can firmly pla-
ce both feet on the passenger
footrests.
Never ride under the influence of
alcohol or other drugs.
This motorcycle is designed for
on-road use only, therefore, it is
not suitable for off-road use.
Protective apparel
The majority of fatalities from
motorcycle accidents are the result of
head injuries. The use of a safety hel-
met is the single most critical factor in
the prevention or reduction of head
injuries.
Always wear an approved hel-
met.
Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impair-
ment of vision which could delay
seeing a hazard.
The use of a jacket, heavy boots,
trousers, gloves, etc., is effective
in preventing or reducing abra-
sions or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on
the control levers, footrests, or
wheels and cause injury or an
accident.
Never touch the engine or
exhaust system during or after
operation. They become very hot
and can cause burns. Always
wear protective clothing that
covers your legs, ankles, and
feet.
Passengers should also observe
the precautions mentioned abo-
ve.

The condition of a vehicle is the
owner’s responsibility. Vital compo-
nents can start to deteriorate quickly
and unexpectedly, even if the vehicle
remains unused (for example, as a
result of exposure to the elements).
Any damage, fluid leakage or loss of
tire air pressure could have serious
consequences. Therefore, it is very
important, in addition to a thorough
visual inspection, to check the follo-
wing points before each ride.
NOTE:
Pre-operation checks should be
made each time the vehicle is used.
Such an inspection can be accom-
plished in a very short time; and the
added safety it assures is more than
worth the time involved.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding

Checking the spark plug
1. Spark plug
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is riddennormally). If the spark plug shows a
distinctly different color, the engine
could be defective. Do not attempt to
diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.
Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4~1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.

Tires
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10440
s s
WARNING
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-re of the tires equals the
ambient temperature).
The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, cargo, and
accessories approved for this
model.
EWA10450
s s
WARNING
Because loading has an enormous
impact on the handling, braking,
performance and safety characte-
ristics of your vehicle, you should
keep the following precautions in
mind.
NEVER OVERLOAD THE VEHI-
CLE! Operation of an overloa-
ded vehicle may result in tire
damage, loss of control, or
severe injury. Make sure that
the total weight of rider, cargo,
and accessories does not
exceed the specified maximum
load for the vehicle.
Do not carry along loosely pac-
ked items, which can shift
during a ride.
Securely pack the heaviest
items close to the center of the
vehicle and distribute the
weight evenly on both sides.
Adjust the suspension and tire
air pressure with regard to the
load.
Check the tire condition and air
pressure before each ride.
Tire air pressure (measured on cold
tires):
Up to 90 kg (198 lb):
Front:
180 kPa (25,6 psi) (1,8 kgf/cm
2)
Rear:
200 kPa (28,4 psi) (2,0 kgf/cm

Brand-new tires can have a
relatively poor grip on certain
road surfaces until they have
been “broken in”. Therefore, it
is advisable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the tire air pres-
sure according to the opera-
ting conditions.
EAU21960
Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpage
before each ride. If any damage
is found, have a Yamaha dealer
replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or crac-
ked wheel must be replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.
EAU22041
Adjusting the clutch lever
free play
1. Free play
The clutch lever free play should mea-
sure 2~5 mm (0,08~0,2 in) as shown.

play and, if necessary, adjust it as
follows.
1. Loosen the locknut at the clutch
lever.
2. To increase the clutch lever free
play, turn the adjusting bolt in
direction (a). To decrease the
clutch lever free play, turn the
adjusting bolt in direction (b).
NOTE:
If the specified clutch lever free play
could be obtained as described abo-
ve, tighten the locknut and skip the
rest of the procedure, otherwise pro-
ceed as follows.
3. Fully turn the adjusting bolt at the
clutch lever in direction (a) to loo-
sen the clutch cable.
4. Loosen the locknut at the crank-
case.
