ACCESSORY INSTALLATION AND
PRECAUTION SAFETY TIPS
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 the 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.
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.
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.
8
Balance the load between the left and
right side of the motorcycle and fasten it
securely.
WARNING
Modification of the motorcycle, or
removal of original equipment may render the vehicle unsafe or illegal.
