SAFETY INFORMATION
2-4
2 cornering clearance, limit suspen-
sion travel, steering travel or con-
trol operation.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution. If accesso-
ries are added to the handlebar
or front fork area, they must be
as lightweight as possible and
should be kept to a minimum.
Bulky or large accessories may
seriously affect the stability of
the motorcycle. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become un-
stable in cross winds.
Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.


Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
motorcycle’s electrical system, anelectric failure could result, which
could cause a dangerous loss of
lights or engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
motorcycle were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, siz-
es, and combinations may not be
appropriate. Refer to page 7-12 for tire
specifications and more information on
replacing your tires.
Transporting the motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.


Remove all loose items from the
motorcycle.


Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.


Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.


Shift the transmission in gear (for
models with a manual transmis-
sion).


Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.


The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce excessive-
ly during transport.
