Helmet holder The helmet holder is located on the bot-
tom of the passenger seat.
To secure a helmet to the helmet
holder
1. Remove the passenger seat. (See
page 3-25.)
2. Attach the helmet to the helmet
holder, and then securely install
the passenger seat. WARNING!
Never ride with a helmet at-
tached to the helmet holder,
since the helmet may hit ob-
jects, causing loss of control
and possibly an accident.
[EWA10161]
To release the helmet from the hel-
met holder
Remove the passenger seat, remove
the helmet from the helmet holder, and
then install the seat.

Storage compartment The storage compartment is located
under the passenger seat. (See page
3-25.)
When storing the Owner’s Manual or
other documents in the storage com-
partment, be sure to wrap them in a
plastic bag so that they will not get wet.
When washing the vehicle, be careful
not to let any water enter the storage
compartment.
WARNING
EWA10961


Do not exceed the load limit of 1
kg (2 lb) for the storage com-
partment.


Do not exceed the maximum
load of 189 kg (417 lb) for the ve-
hicle.

Adjusting the front fork
WARNING
EWA14670
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stability
may result.Each front fork leg is equipped with a
spring preload adjusting bolt, the right
front fork leg is equipped with a re-
bound damping force adjusting screw
and the left front fork leg with a com-
pression damping force adjusting
screw.NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.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 the
suspension, turn the adjusting bolt on
each fork leg in direction (b).
Align the appropriate groove on the ad-
justing mechanism with the top of the
front fork collar.

Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only. To in-
crease the rebound damping force and
thereby harden the rebound damping,
turn the adjusting screw in direction (a).
To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
TIPBe sure to perform this adjustment on
the right front fork leg.
Compression damping force
The compression damping force is ad-
justed on the left front fork leg only. To
increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction (a). To decrease the com-pression damping force and thereby
soften the compression damping, turn
the adjusting screw in direction (b).
TIPBe sure to perform this adjustment on
the left front fork leg.

TIPAlthough the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.

TIPTo obtain a precise adjustment, it is ad-
visable to check the actual total number
of clicks or turns of each damping force
adjusting mechanism. This adjustment
range may not exactly match the spec-

in production.
WARNING
EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.

Do not tamper with or attempt to
open the cylinder assembly.


Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.


Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.


Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.

Luggage strap holders There are four luggage strap holders on
the bottom of the passenger seat. To

Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See page 3-33 for an explanation of
the ignition circuit cut-off system.)
WARNING
EWA10241
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, checkthis system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU44892
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-
lowing functions.

It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is
not pulled.


It prevents starting when the trans-
mission is in gear and the clutch le-
ver is pulled, but the sidestand is
still down.


It cuts the running engine when the
transmission is in gear and the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
