Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit of
203 kg (448 lb). 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 imbal-
ance or instability.

Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.

Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items, in-
cluding such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slowsteering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha cannot
test all other accessories that may be
available, you must personally be re-
sponsible for the proper selection, in-
stallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any ac-
cessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.


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 handle-bar or the front fork area can
create instability due to improper
weight distribution or aerody-
namic 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 at-
tempt to lift the motorcycle, or
the motorcycle may become un-
stable in cross winds. These ac-
cessories 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 free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.

EAU10971
Immobilizer system
This vehicle is equipped with an immo-
bilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the fol-
lowing.

a code re-registering key (with a
red bow)

two standard keys (with a black
bow) that can be re-registered with
new codes

a transponder (which is installed in
the code re-registering key)

an immobilizer unit

the ECU

an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to
a Yamaha dealer to have them re-reg-
istered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
CAUTION:

ECA11820

DO NOT LOSE THE CODE
RE-REGISTERING KEY! CON-
TACT YOUR DEALER IMMEDI-
ATELY IF IT IS LOST! If the code
re-registering key is lost, regis-
tering new codes in the stan-
dard keys is impossible. The
standard keys can still be used
to start the vehicle, however if
code re-registering is required
(i.e., if a new standard key is
made or all keys are lost) the en-
tire immobilizer system must be
replaced. Therefore, it is highlyrecommended to use either
standard key and keep the code
re-registering key in a safe
place.

Do not submerse any key in wa-
ter.

Do not expose any key to exces-
sively high temperatures.

Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).

Do not place heavy items on any
key.

Do not grind any key or alter its
shape.

Do not disassemble the plastic
part of any key.

Do not put two keys of any im-
mobilizer system on the same
key ring.

Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle’s code re-registering key.

WARNING

EWA11020
Because loading has an enormous
impact on the handling, braking,
performance and safety characteris-
tics of your motorcycle, you shouldkeep the following precautions in
mind.

NEVER OVERLOAD THE MO-
TORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and accesso-
ries does not exceed the speci-
fied maximum load for the
vehicle.

Do not carry along loosely
packed items, which can shift
during a ride.

Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.

Adjust the suspension and tire
air pressure with regard to the
load.

Check the tire condition and air
pressure before each ride.Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
NOTE:

The tire tread depth limits may differ
from country to country. Always comply

with the local regulations.
WARNING

EWA10470

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.

The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
WARNING

EWA10900

The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle cannot be guaranteed.

After extensive tests, only the
tires listed below have been ap-
proved for this model by Yama-
ha Motor Co., Ltd.

Always make sure that the valvecaps are securely installed to
prevent air pressure leakage.

Use only the tire valves and
valve cores listed below to
avoid tire deflation during a ride.
