Helmet holding cable A helmet holding cable is provided in
the owner’s tool kit to secure two hel-
mets to the helmet cable holder
equipped on the bottom of the passen-
ger seat.
To secure a helmet with the helmet
holding cable
1. Remove the passenger seat. (See
page 3-19.)
2. Clip the middle snap hook of the
cable onto the cable holder.3. Pass one of the other snap hooks
of the cable through the helmet
strap buckle, and then clip the
snap hook onto the cable holder as
shown.
4. Install the passenger seat.
WARNING
EWA14330
Never ride with a helmet attached to
a helmet holding cable, since the
helmet may hit objects, causing lossof control and possibly an accident.
To release a helmet from the helmet
holding cable
1. Remove the passenger seat.
2. Unfasten the snap hooks from the
cable holder, and then remove the
cable from the helmet strap buck-
le.

Adjusting the front fork This front fork is equipped with spring
preload adjusting bolts, rebound damp-
ing force adjusting screws and com-
pression damping force adjusting bolts.
WARNING
EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof 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 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 collar.Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw on each
fork leg in direction (a). To decrease the
rebound damping force and thereby
soften the rebound damping, turn the
adjusting screw on each fork leg in di-
rection (b).

3Compression damping force
To adjust the compression damping
force (for fast compression damping)To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt on
each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting bolt on
each fork leg in direction (b).
NOTE:The compression damping force set-
ting is determined by measuring dis-
tance A, shown in the illustration. The
longer distance A is, the higher the
compression damping force; the short-
er distance A is, the lower the compres-sion damping force.To adjust the compression damping
force (for slow compression damping)To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt on
each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting bolt on
each fork leg in direction (b).CAUTION:

Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.

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 rebound and compression
damping force adjusting screws.CAUTION:
ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.
Spring preloadTo increase the spring preload and
thereby 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).
NOTE:

Align the appropriate notch in the
adjusting ring with the position in-
dicator on the shock absorber.


Use the special wrench included in
the owner’s tool kit to make the ad-justment.

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
