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 slow
steering response.
Accessories
Genuine Yamaha accessories havebeen 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 orfront 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.

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.
Maximum load:

EAU14781
Adjusting the front fork
This front fork is equipped with spring
preload adjusting bolts and damping
force adjusting screws.
WARNING

EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften thesuspension, turn the adjusting bolt on
each fork leg in direction (b).
NOTE:

Align the appropriate groove on the ad-
justing mechanism with the top of the
front fork cap bolt.
Damping force
1. Turn the adjusting screw on each
fork leg in direction (a) until the
screw moves almost a 1/2 turn
without clicking.
2. Continue turning the adjusting
screw in direction (a) until it clicks.
This is the minimum setting.
3. To increase the damping force,
continue turning the adjusting
screw in direction (a). The third
click after the minimum setting is
the maximum setting. If the adjust-
ing screw is turned further in direc-
tion (a), it will move half a turn
before returning to the minimum
setting.

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
CAUTION:

ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum or
minimum settings.
Spring preload
To increase the spring preload andthereby harden the suspension, turn
the adjusting ring in direction (a). To de-
crease the spring preload and thereby
soften the suspension, turn the adjust-
ing ring in direction (b).

9 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.

Checking and lubricating the
sidestand
The operation of the sidestand should
be checked before each ride, and the
sidestand pivot and metal-to-metal
contact surfaces should be lubricated if
necessary.
WARNING

EWA10730
If the sidestand does not move up
and down smoothly, have a Yamaha
dealer check or repair it.
