SAFETY INFORMATION
products or having other modifications
performed to your vehicle that change
any of the vehicle's design or opera-
tion characteristics can put you and
others at greater risk of serious injury
or death. You are responsible for in-
juries related to changes in the vehi-
cle.
Keep the following guidelines in mind,
as well as those provided under
"Loading" when mounting acces-
sories.
●Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. Care-
fully inspect the accessory before
using it to make sure that it does
not in any way reduce ground
clearance or cornering clearance,
limit suspension travel, steering
travel or control operation, or ob-
scure lights or reflectors.
Accessories fitted to the han-
dlebar or the front fork area can
create instability due to improp-
er weight distribution or aerody-
namic changes. If accessories
are added to the handlebar or
front fork area, they must be aslightweight as possible and
should be kept to a minimum.
Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerody-
namic effects. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become
unstable in cross winds. These
accessories may also cause in-
stability when passing or being
passed by large vehicles.
Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the
freedom of movement of the
operator and may limit control
ability, therefore, such acces-
sories are not recommended.
●Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle's electrical sys-
tem, an electric failure could re-
sult, which could cause a danger-
ous 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 han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
7-16 for tire specifications and more
information on replacing your tires.
