most important in the life of your motorcycle.
Proper break-in operation during this time
will help ensure maximum life and perfor-
mance from your new motorcycle.
Hyosung parts are manufactured of high
uality materials, and manufactured parts
are finished to close tolerances. Proper
break-in operation allows the machined sur-
faces to polish each other and mate
smoothly.
Motorcycle reliability and performance
depend on special care and restraint exer-
cise during the break-in period. It is espe-
cially important that you avoid operating the
engine in a manner which could expose the
engine parts to excessive heat.
Please refer to the BREAK-IN section for
specific break-in recommendations.

There are a great variety of accessories
available to Hyosun owners. Hyosun
can not have direct control over the uality
or suitability of accessories you may wish to
purchase except genuine parts.
The addition of unsuitable accessories
can lead to unsafe operating conditions. It
is not possible for Hyosun to test each
accessory on the market or combinations
of all the available accessories, however,
your dealer can assist you in selecting ual-
ity accessories and installing them correct-
ly.
Use extreme caution when selecting and
installing the accessories for your
Hyosun . We have developed some gen-
eral guidelines which will aid you when
deciding whether, and how to e uip your
motorcycle.
ACCESSORY INSTALLATION AND
PRECAUTION SAFETY TIPS
The most common type of motorcycle
accident occurs when a car travelin
towards a motorcycle turns round
corner in front of the motorcyclist.
Ride defensively.
Wise motorcyclist uses a strate y of
assumin they are invisible to other
drivers, even in broad dayli ht.
Wear bri ht, reflectin clothin .
Do not ride in another driver’s blind
spot.
WARNING
RIDE DEFENSIVELY
Improper accessories or modifica-
tions can make your motorcycle
unsafe and can lead to an accident.
Never modify the motorcycle with
improper or poorly installed acces-
sories. Follow all instructions in this
owner’s manual re ardin acces-
sories and modifications. Use en-
uine Hyosun accessories or equiva-
lent desi ned and tested for your
motorcycle. Consult your Hyosun
dealer if you have any questions.

1. Anytime that additional weight or aero-
dynamic affecting accessories are
installed, they should be mounted as
low as possible, as close to the motor-
cycle and as near the center of gravity
as is feasible. The mounting brackets
and other attachment hardware should
be carefully checked to ensure that it
provides for a rigid, nonmovable
mount. Weak mounts can allow the
shifting of the weight and create a dan-
gerous, unstable condition.
2. Inspect for proper ground clearance
and bank angle. An improperly mount-
ed load could critically reduce these
two safety factors. Also determine that
the loaddoes not interfere with the
operation of the suspension, steering
or other control operations.
3. Accessories fitted to the handlebars or
the front fork area can create serious
stability problems. This extra weight will
cause the motorcycle to be less
responsive to your steering control.
The weight may also cause oscillations
in the front end and lead to instability
problems. Accessories added to the
machine should be as light as possible
and kept to a minimum.
4. The motorcycle may be affected by a
lifting condition or by an instability in
cross winds or when being passed or
passing large vehicles. Improperly
mounted or poorly designed acces-
sories can result in an unsafe riding
condition, therefore caution should be
used when selecting and installing all
accessories.
5. Certain accessories displace the rider
from his or her normal riding position.
This limits the freedom of movement of
the rider and may limit his or her control
ability.
6. Additional electrical accessories may
damage the existing electrical system.
Severe overloads may damage the
wiring harness or create a dangerous
situation due to the loss of electrical
power during the operation of the
motorcycle.
When carrying a load on the motorcycle,
mount it as low as possible and as close as
possible to the machine. An improperly
mounted load can create a high center of
gravity which is very dangerous and makes
the motorcycle difficult to handle. The size
of the loadcan also affect the aerody-
namics and handling of the motorcycle.
Balance the load between the left and
right side of the motorcycle and fasten it
securely.
MODIFICATION
Modification of the motorcycle, or removal
of original e uipment may render the
motorcycle unsafe or illegal.
Obey all applicable e uipment regulations
in your area.

ENGINE COOLANT SOLUTION
Use an engine coolant that is compatible
with aluminum radiator, mixed with distilled
water only at a 50 : 50 mixture ratio for
engine coolant solution.
An engine coolant mixture other than
50 : 50 can affect cooling efficiency or rust
inhibiting peformance.
En ine coolant is harmful or fatal if
swallowed or inhaled.
Do not drink anti-freeze or coolant
solution. If swallowed, do induce
vomitin . Immediately contact a poi-
son control center or a physician.
Avoid inhalin mist or hot vapors ; if
inhaled, remove to fresh air. If coolant
ets in eyes, flush eyes with water
and seek medical attention. Wash
thorou hly after handlin . Solution
can be poisonous to animals.
Keep out of the reach of children and
animals.
