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 further down for an

explanation of the ignition circuit cut-

off system.)

WARNING

The vehicle must not be ridden with

the sidestand down, or if the sides-

tand 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. Yama-

ha’s ignition circuit cut-off system

has been designed to assist the

operator in fulfilling the responsibi-

lity of raising 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 pro-

perly.
