2008 YAMAHA TZR50 ECU

senger, accessories and cargo must
not exceed the maximum load limit.
When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close
to the motorcycle as possible.
Make sure to distribute the
weight as evenly as possible on
both sides of the motorcycle to
minimize imbalance or instability.
Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the
motorcycle before riding. Check
accessory mounts and cargo res-
traints frequently.
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items,
including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or slow
steering response.Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha can-
not test all other accessories that may
be available, you must personally be
responsible for the proper selection,
installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.
Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
Never install accessories or carry
cargo that would impair the per-
formance of your motorcycle.
Carefully inspect the accessory
before using it to make sure that
it does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution oraerodynamic changes. If
accessories 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 due to aerody-
namic effects. Wind may
attempt to lift the motorcycle,
or the motorcycle may become
unstable in cross winds. These
accessories may also cause
instability 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 fre-
edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such
accessories are not recom-
mended.
Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the motorcycle’s electrical sys-
