Q GIVE SAFETY THE RIGHT OF WAY
Scooters 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 your scooter’s value and operating condition. 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 passengers. 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
protective wear, however, should not encourage carelessness. Though 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
defensively - avoiding all dangers, including those caused by others.

FURTHER SAFE RIDING POINTS FOR THIS MODEL
1. Left turn 1. Right turn
EAU02964
8 Be sure to signal clearly when
making turns.
8 Braking can be extremely diffi-
cult on a wet road. Avoid hard
braking, because the scooter
could slide. Apply the brakes
slowly when stopping on a wet
surface.
8 Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
8 Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
8 Street car rails, iron plates on
road construction sites, and
man-hole covers become extremely slippery when wet.
Slow down and cross them with
caution. Keep the scooter upright. It could slide out from under you.
8 The brake lining could get wet
when you wash the scooter. After washing the scooter, check
the brakes before riding.
8 Always wear a helmet, gloves,
trousers (tapered around the
cuff and ankle so they do not
flap), and a bright colored jacket.
1-2
8 Do not carry too much luggage
on the scooter. An overloaded
scooter is unstable.
Use a strong cord to secure any
luggage to the luggage rack. A
loose load will affect the stability of the scooter and could divert your attention from the
road.
