TiresTo maximize the performance, durability,
and safe operation of your motorcycle,
note the following points regarding the
specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
EWA10500
l
l l
l
l
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
l
l l
l
l
The tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger, cargo,
and accessories approved for
this model.
Tire air pressure (measured
on cold tires):0 - 90 kg (0 - 198 lb):
Front:
225 kPa (33 psi) (2.25 kgf/cm²)
Rear:
250kPa (36 psi) (2.50 kgf/cm²)
Loading condition:
90 - 167 kg (198 - 368 lb)
Front:
225 kPa (33 psi) (2.25 kgf/cm²)
Rear:
250 kPa (36 psi) (2.50 kgf/cm²)
Maximum load*:
167 kg (368 lb)
* Total weight of rider, passenger, cargo and accessories
EWA11020
Because loading has an enormous
impact on the handling, braking,
performance and safety
characteristics of your motorcycle,
you should keep the following
precautions in mind.l
l l
l
l
NEVER OVERLOAD THE
MOTORCYCLE! Operation of an
overloaded motorcycle may
result in tire damage, loss of control, or severe injury. Make
sure that the total weight of rider,
passenger, cargo, and
accessories does not exceed the
specified maximum load for the
vehicle.
l
l l
l
l
Do not carry along loosely
packed items, which can shift
during a ride.
l
l l
l
l
Securely pack the heaviest items
close to the center of the
motorcycle and distribute the
weight evenly on both sides.
l
l l
l
l
Adjust the suspension and tire
air pressure with regard to the
load.
l
l l
l
l
Check the tire condition and air
pressure before each ride.

PERIODIC MAINTENANCE AND MINOR REPAIRTire inspection1. Tire sidewall
2. Tire tread depthThe tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the sidewall
is cracked, have a Yamaha dealer
replace the tire immediately.Minimum tire tread depth (frontand rear):
1.6 mm (0.06 in)The tire tread depth limits may differ from
country to country. Always comply with
the local regulations.
Tire information
This motorcycle is equipped with cast
wheels and tubeless tires.
EWA10460
l
l l
l
l
The front and rear tires should
be of the same make and design,
otherwise the handling
characteristics of the vehicle
cannot be guaranteed.
After extensive tests, only the
tires listed below have been
approved for this model by
Yamaha.
Front tire:
Size: 100/80-17M/C (52S)
Manufacturer/model: PIRELLI / SPORT DEMON
Rear tire:
Size: 130/70-17M/C (62S)
Manufacturer/model:
PIRELLI / SPORT DEMON
EWA10470

l
l
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
l
l l
l
l
The replacement of all wheel and
brake related parts, including the
tires, should be left to a Yamaha
dealer, who has the necessary
professional knowledge and
experience.

MOTORCYCLE CARE AND STORAGE

After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge, and
then rinse thoroughly with clean water.
Use a toothbrush or bottlebrush for hard-
to-reach areas. Stubborn dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few
minutes before cleaning.After riding in the rain, near the sea oron salt-sprayed roads
Since sea salt or salt sprayed on roads
during winter are extremely corrosive in
combination with water, carry out the
following steps after each ride in the rain,
near the sea or on salt-sprayed roads.Salt sprayed on roads in the winter may
remain well into spring.1. Clean the motorcycle with coldwater and a mild detergent, after
the engine has cooled down.
ECA10790
Do not use warm water since it
increases the corrosive action of the
salt.2. Apply a corrosion protection sprayon all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning 1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Immediately dry the drive chain and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recommended to apply a corrosion
protection spray on all metal,
including chrome- and nickel-
plated, surfaces. 5. Use spray oil as a universal cleaner
to remove any remaining dirt.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely before storing or covering it.
EWA11130

Make sure that there is no oil or
wax on the brakes or tires.
If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires with
warm water and a mild
detergent. Before riding at
higher speeds, test the
motorcycle’s braking
performance and cornering
behavior.

Apply spray oil and wax
sparingly and make sure to wipe
off any excess.

7pedals as well as of the sidestand/
centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground.
Alternatively, turn the wheels a little
every month in order to prevent the
tires from becoming degraded in
one spot.
6. Cover the muffler outlets with plastic bags to prevent moisture
from entering them.
7. Remove the battery and fully charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an
excessively cold or warm place
[less than 0 °C (30 °F) or more than
30 °C (90 °F)]. For more information
on storing the battery, see page
6-25~6-26.
Make any necessary repairs before
storing the motorcycle.
