Adjusting the shock
absorber assemblies
EWA10210
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Each shock absorber assembly is
equipped with a spring preload adjus-
ting ring.
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock
absorber assembly in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring on each shock absor-
ber assembly in direction (b).Align the appropriate notch in the
adjusting ring with the position indica-
tor on the shock absorber.

Sidestand
1. Sidestand switch
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See page 3-19 for an
explanation of the ignition circuit cut-
off system.)

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.
EAU45051
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand is still down.
It 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.

Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.

TIP
This model is equipped with a lean
angle sensor to stop the engine in
case of a turnover. To start the engine
after a turnover, be sure to turn the
main switch to “OFF” and then to
“ON”. Failing to do so will prevent the
engine from starting even though the
engine will crank when pushing the
start switch.

If the engine does not start, rele-
ase the start switch, wait a few
seconds, and then try again.
Each starting attempt should be
as short as possible to preserve
the battery. Do not crank the

BrakingEWA10300
Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.Front

EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).
