Rebound damping force
To increase the rebound damping
force and thereby harden the
rebound damping, turn the adjusting
knob in direction a. To decrease the
rebound damping force and thereby
soften the rebound damping, turn the
adjusting knob in direction b.
1. Rebound damping force adjusting knob
Minimum (soft) 20 clicks in direction b*
Standard 12 clicks in direction b*
Maximum (hard) 3 clicks in direction b*
* With the adjusting knob fully turned in direction a
Compression damping force
To increase the compression damp-
ing force and thereby harden the
compression damping, turn the
adjusting knob in direction a. To
decrease the compression damping
force and thereby soften the com-
pression damping, turn the adjusting
knob in direction b.
1. Compression damping force adjusting
knob
Minimum (soft) 12 clicks in direction b*
Standard 11 clicks in direction b*
Maximum (hard) 1 clicks in direction b*
* With the adjusting knob fully turned in direction a
NOTE:
Although the total number of clicks of
a damping force adjusting mecha-
nism may not exactly match the
above specifications due to small dif-
ferences 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 number of
clicks of each damping force adjust-
ing mechanism and to modify the
specifications as necessary.

This shock absorber contains
highly pressurized nitrogen gas.
For proper handling, read and
understand the following informa-
tion before handling the shock
absorber. The manufacturer can-
not be held responsible for proper-
ty damage or personal injury that
may result from improper han-
dling.
8Do not tamper with or attempt
to open the gas cylinder.
8Do not subject the shock
absorber to an open flame or
other high heat sources, other-
wise it may explode due to
excessive gas pressure.
8Do not deform or damage the
gas cylinder in any way, as
this will result in poor damp-
ing performance.
8Always have a Yamaha dealer
service the shock absorber.

Luggage strap holdersLuggage strap holdersThere are four luggage strap holders
below the passenger seat, two of
which can be turned out for easier

SidestandSidestandThe sidestand is located on the left
side of the frame. Raise the side-
stand or lower it with your foot while
holding the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)

The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact 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 responsibility of rais-
ing the sidestand before starting
off. Therefore, check this system
regularly as described below and
have a Yamaha dealer repair it if it
does not function properly.

Ignition circuit cut-off
system
Ignition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
8It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
8It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the
sidestand is still down.
8It 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.

If a malfunction is noted, have a
Yamaha dealer check the system
before riding.

2. Make sure that the engine stop switch is set to “
#”.
3. Turn the key to “ON”.
4. Shift the transmission into the neutral position.
5. Push the start switch.
Does the engine start?

The motorcycle should not be ridden until
checked by a Yamaha dealer.
With the engine still running:
6. Move the sidestand up.
7. Keep the clutch lever pulled.
8. Shift the transmission into gear.
9. Move the sidestand down.
Does the engine stall?
After the engine has stalled:
10. Move the sidestand up.
11. Keep the clutch lever pulled.
12. Push the start switch.
Does the engine start?
The sidestand switch may be defective.
The motorcycle should not be ridden until
checked by a Yamaha dealer.

PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a
very short time; and the added safety it assures is more than worth the time involved.

If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operat-
ing the motorcycle.
