To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.NOTE:●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.

TiresTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
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
w● ●● ●
●
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
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, passenger,
cargo, and accessories ap-
proved for this model.
Tire air pressure (measured on cold
tires):
Up to 90 kg (198 lb):
Front:
175 kPa (25 psi) (1.75 kgf/cm

EWA11200
wBecause loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics
of your vehicle, you should keep the
following precautions in mind.● ●● ●
●
NEVER OVERLOAD THE VE-
HICLE! Operation of an over-
loaded 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.
● ●● ●
●
Do not carry along loosely
packed 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 tire air pressure with
regard to the load.
Check the tire condition and air
pressure before each ride.

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the ve-
hicle with excessively worn tires
decreases riding stability and
can lead to loss of control.
● ●● ●
●
The replacement of all wheel andbrake related parts, including the
tires, should be left to a Yamaha
dealer, who has the necessary
professional knowledge and ex-
perience.

Cast wheelsTo 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 be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
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 han-
dling characteristics, and a short-
ened 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 characteris-
tics.
