SAFETY INFORMATION
EAU53005
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before
riding this motorcycle.
He or she should:
Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.

Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.

Obtain qualified training in safe
and proper riding techniques.

Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.

Never operate a motorcycle with-
out proper training or instruction. Take a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized motorcycle dealer to find out
about the training courses nearest
you.
Safe Riding
Perform the pre-operation checks each
time you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment damage. See page 4-1
for a list of pre-operation checks.

This motorcycle is designed to car-
ry the operator only.

No passengers.

This motorcycle is intended to use
as a competition model including
enduro usage.

This motorcycle is not designed
nor intended for continuous
“Paved Road” use. Never use this
motorcycle on highway (motor-
way)/expressway.

If any of the components that are
necessary for the vehicle to com-
ply with regulations are modified or replaced with non-specified com-
ponents, the vehicle will no longer
meet the regulations.

Watch carefully for other vehicles
when operating on unpaved public
streets or roads. Make sure you
know your country’s laws and reg-
ulations before you ride on un-
paved public streets or roads.

The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did
not see the motorcycle. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
Wear a brightly colored jacket.
Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.
Ride where other motorists can see you. Avoid riding in another
