d. Hold the spring gauge at a 90° angle from the 
handlebar, pull the spring gauge, and then 
record the measurement when the handlebar 
starts to run.
e. Repeat the above procedure on the opposite 
handlebar.
f. If the steering head tension is out of specifica-
tion (both handlebars should be within speci-
fication), remove the upper bracket and 
loosen or tighten the lower ring nut.
g. Reinstall the upper bracket and measure the 
steering head tension again as described 
above.
h. Repeat the above procedure until the steer-
ing head tension is within specification.
i. Grasp the bottom of the front fork legs and 
gently rock the front fork.
Binding/looseness → Adjust the steering 
head.

WARNING
EWA13120
Securely support the vehicle so that there is 
no danger of it falling over.
2. Check:
Inner tube “1”
Damage/scratches → Replace.
Oil seal “2”
Oil leakage → Replace.3. Hold the vehicle upright and apply the front 
brake.
4. Check:

CHECKING THE TIRES
The following procedure applies to both of the 
tires.
1. Check:
Tire pressure
Out of specification → Regulate.
WARNING
EWA13180
The tire pressure should only be checked 
and regulated when the tire temperature 
equals the ambient air temperature.
The tire pressure and the suspension must 
be adjusted according to the total weight 
(including cargo, rider, passenger and ac-
cessories) and the anticipated riding 
speed.
Operation of an overloaded vehicle could 
cause tire damage, an accident or an injury.
NEVER OVERLOAD THE VEHICLE.
WARNING
EWA13190
It is dangerous to ride with a worn-out tire. 
When the tire tread reaches the wear limit, re-
place the tire immediately.
2. Check:
Tire surfaces
Damage/wear → Replace the tire. Direction “a” (turn in)
Compression damping is increased 
(suspension is harder).
Direction “b” (turn out)
Compression damping is decreased 
(suspension is softer).

WARNING
EWA14080
Do not use a tubeless tire on a wheel de-
signed only for tube tires to avoid tire fail-
ure and personal injury from sudden 
deflation.
When using a tube tire, be sure to install the 
correct tube.
Always replace a new tube tire and a new 
tube as a set.
To avoid pinching the tube, make sure the 
wheel rim band and tube are centered in the 
wheel groove.
Patching a punctured tube is not recom-
mended. If it is absolutely necessary to do 
so, use great care and replace the tube as 
soon as possible with a good quality re-
placement.
WARNING
EWA14090
After extensive tests, the tires listed below 
have been approved by Yamaha Motor Co., 
Ltd. for this model. The front and rear tires 
should always be by the same manufacturer and of the same design. No guarantee con-
cerning handling characteristics can be giv-
en if a tire combination other than one 
approved by Yamaha is used on this vehicle.
WARNING
EWA13210
New tires have a relatively low grip on the 
road surface until they have been slightly 
worn. Therefore, approximately 100 km 
should be traveled at normal speed before 
any high-speed riding is done.
NOTE:
For tires with a direction of rotation mark “1”:
Install the tire with the mark pointing in the di-
rection of wheel rotation.
Align the mark “2” with the valve installation 
point.

NOTE:
After a tire or wheel has been changed or re-
placed, always balance the wheel.

CHECKING AND LUBRICATING THE 
CABLES
The following procedure applies to all of the in-
ner and outer cables.
WARNING
EWA13270
Damaged outer cable may cause the cable to 
corrode and interfere with its movement. Re-
place damaged outer cable and inner cables 
as soon as possible.
1. Check:
Outer cable
Damage → Replace.
2. Check:
Cable operation
Rough movement → Lubricate.
NOTE:
Hold the cable end upright and pour a few drops 
of lubricant into the cable sheath or use a suit-
able lubricating device.

REPLACING THE HEADLIGHT BULBS
The following procedure applies to both of the 
headlight bulbs.
1. Remove:
Headlight bulb cover “1”
2. Disconnect:
Headlight coupler “1”
3. Detach:

WARNING
EWA13320
Since the headlight bulb gets extremely hot, 
keep flammable products and your hands 
away from the bulb until it has cooled down.
5. Install:
Headlight bulb 
Secure the new headlight bulb with the head-
light bulb holder.
CAUTION:
ECA13690
Avoid touching the glass part of the head-
light bulb to keep it free from oil, otherwise 
the transparency of the glass, the life of the 
bulb and the luminous flux will be adversely 
affected. If the headlight bulb gets soiled, 
thoroughly clean it with a cloth moistened 
with alcohol or lacquer thinner.
