SAFETY INFORMATION
2-4

Never install accessories that
would impair the performance 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 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, an
electric 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 7-15 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.

NOTICE
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it.
EAU23283
Checking the steering Worn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the pe-
riodic maintenance and lubrication
chart.1. Place a stand under the engine to raise the front wheel off the
ground. (See page 7-28 for more
information.) WARNING! To
avoid injury, securely support
the vehicle so there is no danger
of it falling over.
[EWA10751]
2. Hold the lower ends of the front fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steering.
EAU23291
Checking the wheel bearings The front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrica-
tion chart. If there is play in the wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer check
the wheel bearings.
