Storage compartment This storage compartment is designed
to hold an optional genuine Yamaha
CYCLELOK. (Other locks may not fit.)
When placing a CYCLELOK in the stor-
age compartment, securely fasten it
with the straps. When the CYCLELOK
is not in the storage compartment, be
sure to secure the straps to prevent los-
ing them.

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 motorcycle, be
careful not to let any water enter the
storage compartment.

Adjusting the front fork 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.
WARNING
EWA14670
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stabilitymay result.
Spring preloadTo 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).
NOTE:Align the appropriate groove on the ad-
justing mechanism with the top of thefront fork cap bolt.

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).
NOTE:Be sure to perform this adjustment onthe 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 dampingforce 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).
NOTE:Be sure to perform this adjustment onthe left front fork leg.CAUTION:

NOTE:Although 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 thespecifications as necessary.

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

Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.
Spring preloadTo increase the spring preload and
thereby harden the suspension, turn

3 Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, 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).
NOTE:Although the total number of clicks of
the rebound damping force adjusting
mechanism may not exactly match the

ences in production, the actual number
of clicks always represents the entire

justment, it would be advisable to check
the number of clicks of the rebound
damping force adjusting mechanism
and to modify the specifications as nec-essary.
WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.

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


Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.


Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.


Always have a Yamaha dealerservice the shock absorber.

EXUP system This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.CAUTION:
ECA15610
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-mance of or damage to the engine.
EAU15301
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.NOTE:The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation ofthe ignition circuit cut-off system.)
WARNING
EWA10240
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, check
this system regularly as described

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 sid-
estand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.WARNING
EWA10260


The vehicle must be placed on
the centerstand during this in-
spection.


If a malfunction is noted, have a
Yamaha dealer check the sys-tem before riding.

PRE-OPERATION CHECKS

EAU15591
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.NOTE:Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very shorttime; and the added safety it assures is more than worth the time involved.
WARNING
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operatingthe vehicle.
