2008 YAMAHA TZR50 warning

NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned 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
coolant reservoir.
NOTE:
The coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, open thereservoir cap, add coolant to the
maximum level mark, and then
close the reservoir cap.

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.
EWA10500
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, passenger,
cargo, and accessories appro-
ved for this model.EWA11020
s s
WARNING
Because loading has an enormous
impact on the handling, braking,
performance and safety characte-
ristics of your motorcycle, you
should keep the following precau-
tions in mind.
NEVER OVERLOAD THE
MOTORCYCLE! Operation of
an overloaded motorcycle may
result in tire damage, loss ofcontrol, 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 pac-
ked items, which can shift
during a ride.
Securely pack the heaviest
items close to the center of the
motorcycle 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 psi) (1.8 kgf/cm
2)
Rear:
200 kPa (28 psi) (2.0 kgf/cm

90 kg (198 lb) to maximum load:
Front:

Tire inspection
1. Tire tread depth
The 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 Yama-
ha dealer replace the tire immediately.
NOTE:
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.

WARNING
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 Motor España, S.A.
EWA10470
s s
WARNING
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.
The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.

WARNING
You are hereby informed that any
attempt to change the engine or
any other part to increase the sco-
oter’s performance or power is
strictly forbidden by law.
Any change resulting in an
increase of the vehicle’s maxi-
mum speed or in an increase of
the engine’s capacity entails a
category classification shift
from scooter to light motorcy-
cle, with all the consequences
relating to the latter category,
compelling the owner to:
- proceed with a new certifica-
tion,
- have the vehicle registered,
- hold a driving license (pur-
suant to the new legislation).
In addition, you are informed that
such changes will bar you from
insurance coverage insofar as
insurance policies expressly stipu-
late that such technical changes
brought with a view to enhancing
performance are forbidden.
For the above-mentioned reasons,
any violation of the rules forbidding
personal or otherwise third-party
interventions is punishable by law
with penalties (including seizure of
the vehicle) to which, as the case
may be, penalties may be added
relating to the failure to wear a

Improper drive chain slack will
overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.
4. Tighten the locknuts, and then
tighten the axle nut to the speci-
fied torque.
5. Insert a new cotter pin into the
axle nut, and then bend its ends
