SidestandSidestandThe sidestand is located on the left
side of the frame. Raise the side-
stand or lower it with your foot while
holding the scooter upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)

Ignition circuit cut-off
system
Ignition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the follow-
ing functions.
8It prevents starting when the
sidestand is up, but neither brake
is applied.
8It prevents starting when either
brake is applied, but the side-
stand is still down.
8It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
EW000045
w
If a malfunction is noted, have a
Yamaha dealer check the system
before riding.
EW000044
w
The scooter must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact 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 responsibility of rais-
ing 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 properly.

PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thorough-
ly understand.
8 8
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
8 8
For safety, always start the
engine with the centerstand
down.

When the key is turned to “ON”,
the ABS warning light should
come on for a few seconds, and
then go off. If the ABS warning
light does not come on or remains
on, have a Yamaha dealer inspect
the electrical circuit.

3. Start the engine by pushing the
start switch while applying the
front or rear brake.
NOTE:
If the engine does not start, release
the start switch, wait a few seconds,
and then try again. Each starting
attempt should be as short as possi-
ble to preserve the battery. Do not
crank the engine more than 10 sec-
onds on any one attempt. If the
engine does not start, try with the
throttle open 1/8 turn.

For maximum engine life, never
accelerate hard when the engine is
cold!

Acceleration and decelerationThe speed can be adjusted by open-
ing and closing the throttle. To
increase the speed, turn the throttle
grip in direction a. To reduce the
speed, turn the throttle grip in direc-

BrakingBraking1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.

8 8
Avoid braking hard or sudden-
ly (especially when leaning
over to one side), otherwise
the scooter may skid or over-
turn.
8 8
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore,
slow down when approaching
such areas and cross them
with caution.
8 8
Keep in mind that braking on a
wet road is much more diffi-
cult.
8 8
Ride slowly down a hill, as
braking downhill can be very
difficult.
