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.
WARNING
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU45310
TIPThis model is equipped with a lean an-
gle 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”. Fail-
ing to do so will prevent the engine from
starting even though the engine will
crank when pushing the start switch.
EAU45422
Starting the engine NOTICE
ECA10250
See page 5-4 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.In order for the ignition circuit cut-off
system to enable starting, the side-
stand must be up.
See page 3-12 for more information.
1. Turn the key to “ON”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake. NOTICE: For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!
[ECA11041]
If the engine fails to start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the bat-
tery. Do not crank the engine more
than 5 seconds on any one at-
tempt.

Braking
WARNING
EWA10300


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.
EAU16820
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
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 crossings).

Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU45581
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to changethe engine oil and final transmission
oil, and to clean the oil strainer.
[ECA16501]1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17213
Parking When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10311


Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.


Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.


Do not park near grass or other
flammable materials which
might catch fire.

PERIODIC MAINTENANCE AND ADJUSTMENT

EAU17241
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, depending on the
weather, terrain, geographical location,
and individual use, the maintenance in-
tervals may need to be shortened.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle 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
EWA15121
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 1-1 for more in-
formation about carbon monox-
ide.

TIP

The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.


From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.

Air filter
This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.


V-belt case air filter
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.


Hydraulic brake service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
Replace the brake hose every four years and if cracked or damaged.
