Adjusting the shock absorber
assembly This shock absorber assembly is
equipped with a spring preload adjust-
ing nut.NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.Adjust the spring preload as follows.1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspension,
turn the adjusting nut in direction
(a). To decrease the spring pre- load and thereby soften the sus-
pension, turn the adjusting nut in
direction (b).
●
To make the adjustment, use
the special wrench and exten-
sion bar included in the addi-
tional tool kit, which was
handed out separately at the
purchase of the vehicle.
●
The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The shorter distance A is,
the higher the spring preload;
the longer distance A is, the
lower the spring preload. With
each complete turn of the ad-
justing nut, distance A is
changed by 2.0 mm (0.08 in).

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.

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 inner diameter of the exhaust
pipe. The EXUP system valve is con-
stantly adjusted in accordance with the
engine speed by a computer-controlled
servomotor.NOTICE
ECA10191
●
The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
●
If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-
er check it.
Spring preload: Minimum (soft):Distance A = 171 mm (6.73 in)
Standard:
Distance A = 171 mm (6.73 in)
Maximum (hard): Distance A = 162 mm (6.38 in)
Tightening torque: Locknut:
30 Nm (3.0 m·kgf, 22 ft·lbf)

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 the following section for an expla-
nation of the ignition circuit cut-off sys-
tem.)
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, check this system regularly and have a
Yamaha dealer repair it if it does not function properly.

Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-

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.
