OPERATION AND IMPORTANT RIDING POINTS

EAU16782
Acceleration and decelerationThe speed can be adjusted by opening
and closing the throttle. To increase
the speed, turn the throttle grip in di-
rection (a). To reduce the speed, turn
the throttle grip in direction (b).
EAU16794
Braking
WARNING
EWA10301
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
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 cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.Front

PERIODIC MAINTENANCE AND ADJUSTMENT

EAU17245
Periodic inspection, adjustment, and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The most im-
portant points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10322
Failure to properly maintain the vehi-
cle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15123
Turn off the engine when performing
maintenance unless otherwise
specified.
A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-3 for more in-
formation about carbon monox-
ide.
WARNING
EWA15461
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.
EAU17303
Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and
equipped to perform these particular
services.

6Tire information
This model is equipped with tubeless
tires.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10472
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience to do so.
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.
EAU21963
Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be
checked for cracks, bends, warp-
age or other damage before each
ride. If any damage is found, have
a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed or cracked wheel must be
replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Checking the front brake lever
free playThe brake lever free play should mea-
sure 10.0–20.0 mm (0.39–0.79 in) as
shown. Periodically check the brake le-
ver free play and, if necessary, have a
Yamaha dealer check the brake sys-
tem.
WARNING
EWA10642
An incorrect brake lever free play in-
dicates a hazardous condition in the
brake system. Do not operate the
vehicle until the brake system has
been checked or repaired by a
Yamaha dealer.
EAU22171
Adjusting the rear brake lever
free playThe brake lever free play should mea-
sure 10.0–20.0 mm (0.39–0.79 in) as
shown. Periodically check the brake le-
ver free play and, if necessary, adjust it
as follows.
To increase the brake lever free play,
turn the adjusting nut at the brake shoe
plate in direction (a). To decrease the
brake lever free play, turn the adjusting
nut in direction (b).
WARNING
EWA10651
If proper adjustment cannot be ob-
tained as described, have a Yamaha
dealer make this adjustment.

Checking the front brake pads
and rear brake shoes The front brake pads and the rear
brake shoes must be checked for wear
at the intervals specified in the periodic
maintenance and lubrication chart.
EAU22401
Front brake pads
Check each front brake pad for dam-
age and measure the lining thickness.
If a brake pad is damaged or if the lin-
ing thickness is less than 3.1 mm (0.12
in), have a Yamaha dealer replace the
brake pads as a set.
EAU22541
Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check
the brake shoe wear without having to
disassemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.
EAU37003
Checking the brake fluid levelBefore riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.
WARNING

loss of braking ability. Observe
