QGIVE SAFETY THE RIGHT OF WAY
1Scooters are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom.
However, they also impose certain limits, which you must accept; even the best scooter does not
ignore the laws of physics.
Regular care and maintenance are essential for preserving value and operating condition of your
scooter. Moreover, what is true for the scooter is also true for the rider: good performance depends on
being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of
the question. Scooter riders—more than car drivers—must always be at their mental and physical
best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous
risks.
Protective clothing is as essential for the scooter rider as seat belts are for car drivers and passen-
gers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic
materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum pro-
tective wear, however, should not encourage carelessness. Although full-coverage helmets and suits,
in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable.
Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is
even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensive-
ly—avoiding all dangers, including those caused by others.
Enjoy your ride!

Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the scooter near
possible fire hazards such as
grass or other materials that
easily burn.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

This scooter is designed for use
on paved roads only. If this scoot-
er is operated in abnormally dusty,
muddy or wet conditions, the air
filter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for prop-
er maintenance intervals.
