Sidestand
This model is equipped with an ignition
circuit cut-off system. The motorcycle
must not be ridden when the sidestand
is down. The sidestand is located on
the left side of the frame. (Refer to
page 5-1 for an explanation of this sys-
tem.)
EW000044
This motorcycle must not be operat-
ed with the sidestand in the down
position. If the stand is not properly
retracted, it could contact the
ground and distract the operator, re-
sulting in a possible loss of control.
Yamaha has designed into this mo-
torcycle a lockout system to assist
the operator in fulfilling the respon-
sibility of retracting the sidestand.
Please check carefully the operating
instructions listed below and if there
is any indication of a malfunction,
return the motorcycle to a Yamaha
dealer immediately for repair.

PRE-OPERATION CHECKS
/Net/layout8/layout_G2/work/Imai_work/OM-PS/AA9156_XJ600SN-E6/English/E-4.frame
Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.
EAU00340

EAU00373
lBefore riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
lNever start your engine or let it
run for any length of time in a
closed area. The exhaust fumes
are poisonous and can cause
loss of consciousness and
death within a short time. Al-
ways operate your motorcycle
in an area with adequate ventila-
tion.
lBefore starting out, always be
sure the sidestand is up. Failure
to retract the sidestand com-
pletely can result in a serious
accident when you try to turn a
corner.
EAU00381

This motorcycle is equipped with an ig-
nition circuit cut-off system. The engine

lThe sidestand is up, the transmis-
sion is in gear and the clutch is dis-
engaged.
The motorcycle must not be ridden
