SAFETY INFORMATION

• Always obey the speed limitand 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 bothhands on the handlebar and
both feet on the operator
footrests during operation to
maintain control of the motor-
cycle.
• The passenger should always hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep
both feet on the passenger
footrests.
• Never carry a passenger un- less he or she can firmly place
both feet on the passenger
footrests.
●Never ride under the influence of
alcohol or other drugs. Protective apparel
The majority of fatalities from motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is the
single most critical factor in the pre-
vention or reduction of head injuries.
●Always wear an approved helmet.
●Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that 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 ac-
cident.
●Never touch the engine or ex-
haust system during or after oper-
ation. 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 above.Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the re-
moval of original equipment, may ren-
der the motorcycle unsafe for use and
may cause severe personal injury.
Modifications may also make your mo-
torcycle illegal to use.
Loading and accessories
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 are some general guidelines to
follow if loading cargo or adding ac-
cessories to your motorcycle:

WARNING0
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-
torcycle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel-
and brake-related parts, in-
cluding the tires, should be left
to a Yamaha dealer, who has
the necessary professional
knowledge and experience.
●It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.

EAU21940
Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.
●The wheel rims should be
checked for cracks, bends or
warpage, and the spokes for
looseness or damage 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 de-
formed or cracked wheel must be
replaced.
●The wheel should be balancedwhenever 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 afterchanging a tire since the tire sur-
face must first be "broken in" for it
to develop its optimal characteris-
tics.

●Oil seals: Replace every two
years.
●Brake hoses: Replace every four

ECA10570
CAUTION:
Improper drive chain slack will
overload the engine as well as oth-
er vital parts of the motorcycle and
can lead to chain slippage or break-
age. To prevent this from occurring,
keep the drive chain slack within
the specified limits.
3. Tighten the locknuts, then the axle nut to their specified torques.
Tightening torques:
Locknut:16 Nm (1.6 m·kgf, 11 ft·lbf)
Axle nut: 105 Nm (10.5 m·kgf, 75 ft·lbf)
EAU34311
To adjust the drive chain slack1. Loosen the axle nut and the lock- nut on each side of the swingarm.
2. To tighten the drive chain, turn the adjusting bolt on each side of the
swingarm in direction (a). To
loosen the drive chain, turn the
adjusting bolt on each side of the
swingarm in direction (b), and
then push the rear wheel forward.
NOTE:
Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same po-
sition for proper wheel alignment.
