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.

The condition of a vehicle is the owner’s responsibility.
Vital components can start to deteriorate quickly and unexpectedly, even if the vehicle remains unused (for example, as a result of ex-
posure to the elements).
Any damage, fluid leakage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a
thorough visual inspection, to check the following points before each ride.
