Adjusting the front fork
This front fork is equipped with spring pre-
load adjusting bolts.
EW000035WARNING0
Always adjust both fork legs equally,
otherwise poor handling and loss of
stability may result.
Adjust the spring preload as follows.
To increase the spring preload and thereby
harden the suspension, turn the adjusting
bolt on each fork leg in direction a. To de-
crease the spring preload and thereby
soften the suspension, turn the adjusting
bolt on each fork leg in direction b.
NOTE:
Align the appropriate groove on the adjust-
ing mechanism with the top of the front
fork cap bolt.

the adjusting nut in direction b.
NOTE:
Use the special wrench included in the
owner’s tool kit to make the adjustment.
The spring preload setting is determined
by measuring distance A, shown in the
illustration. The longer distance A is, the
higher the spring preload; the shorter dis-
tance A is, the lower the spring preload.
With each complete turn of the adjusting
nut, distance A changes by 1.5 mm.3. Tighten the locknut to the specified
torque.• Always have a Yamaha dealer ser-
vice the shock absorber.

Sidestand
The sidestand is located on the left side of
the frame. Raise the sidestand 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 situations. (See fur-
ther down for an explanation of the ignition
circuit cut-off system).

EAU00315WARNING0
This shock absorber contains highly
pressurized nitrogen gas. For proper
handling, read and understand the fol-
lowing information before handling the
shock absorber. The manufacturer can-
not be held responsible 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 absorber
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 perfor-
mance.
EAU00027

INSTRUMENT AND CONTROL FUNCTIONS
EW000044WARNING0
The motorcycle 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 side-
stand could contact the ground and
distract the operator, resulting in a pos-
sible loss of control.
Yamaha’s ignition circuit cut-off sys-
tem has been designed to assist the
operator in fulfilling the responsibility
of raising the sidestand before starting
off. Therefore, check this system regu-
larly as described below and have a
Yamaha dealer repair it if it does not
function properly.
EAU03720
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch, clutch switch
and neutral switch) has the following func-
tions.
•It prevents starting when the trans-
mission is in gear and the sidestand
is up, but the clutch lever is not
pulled.
•It prevents starting when the trans-
mission is in gear and the clutch lever
is pulled, but the sidestand is still
down.
•It cuts the running engine when the
transmission is in gear and the side-
stand is moved down.Periodically check the operation of the ig-
nition circuit cut-off system according to
the following procedure.
EW000045WARNING0
If a malfunction is noted, have a Yamaha
dealer check the system before riding.
