FAMILIARIZE YOURSELF WITH
THE MOTORCYCLE
KNOW YOUR LIMITS
BE EXTRA SAFETY CONSCIOUS
ON BAD WEATHER DAYS
Your riding skill and mechanical
knowledge form the foundation for safe
riding practices.
We suggest that you practice riding
your motorcycle in a non-traffic situation
until you are thoroughly familiar with
your machine and its controls.
Remember practice makes perfect.
WARNING
Ride within the boundaries of your own
skill at all times. Knowing these limits
and staying within them will help you to
avoid accidents.
WARNING
Riding on bad weather days, especially
wet ones, requires extra caution.
Braking distances double on a rainy
day. Stay off of the painted surface
marks, manhole covers and greasy
appearing areas as they can be
especially slippery.
Use extreme caution at railway
crossings and on metal gratings and
bridges. Whenever you have a doubt
about road condition, slow down!
WARNING
INSPECTION BEFORE RIDING
Review thoroughly the instructions in
the “INSPECTION BEFORE RIDING”
section of this manual. Do not forget to
perform an entire safety inspection to
ensure the safety of the rider and its
passenger.
WARNING

10
1. In case that additional weight or
aerodynamic affecting accessories are
installed, they should be mounted as
low as possible, as close to the
motorcycle 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 dangerous, unstable condition.
2. Inspect for proper ground clearance
and bank angle. An improperly
mounted 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
accessories can result in an unsafe
riding condition, therefore caution
should be used when selecting and
installing all accessories.
There are a great variety of accessories
available to Hyosung owners. Hyosung
can not have direct control over the quality
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 Hyosung to test each
accessory on the market or combinations
of all available accessories, however, your
dealer can assist you in selecting quality
accessories and installing them correctly.
Use extreme caution when selecting and
installing the accessories for your
Hyosung. We have developed some
general guidelines which will aid you when
deciding whether, and how to equip your
motorcycle.
ACCESSORY INSTALLATION AND
PRECAUTION SAFETY TIPS
Improper accessories or modifications
can make your motorcycle unsafe and
can lead to an accident.
Never modify the motorcycle with
improper or poorly installed
accessories. Follow all instructions in
this owner’s manual regarding
accessories and modifications. Use
genuine Hyosung accessories or
equivalent designed and tested for
your motorcycle. Consult your
Hyosung dealer if you have any
questions.
WARNING

11
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
aerodynamics and handling of the
motorcycle.
Balance the load between the left and
right side of the motorcycle and fasten it
securely.
Modification of the motorcycle, or removal of
original equipment may render the vehicle
unsafe or illegal.
Obey all applicable equipment regulations in
your area.
