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 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 passengers.
Always wear a complete scooter suit (whether made of leather or tear-resistant synthetic materials with
protectors) sturdy boots scooter gloves and a properly fitting helmet. Optimum protective wear however
should not encourage carelessness. Although full-coverage helmets and suits in particular create an illu-
sion 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.
Enjoy your ride!

Further safe-riding points
•Be sure to signal clearly when making turns.
•Braking can be extremely difficult on a wet road. Avoid hard braking because the scooter could slide.
Apply the brakes slowly when stopping on a wet surface.
•Slow down as you approach a corner or turn. Once you have completed a turn accelerate slowly.
•Be careful when passing parked cars. A driver might not see you and open a door in your path.
•Railroad crossings streetcar rails iron plates on road construction sites and manhole covers become
extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright otherwise
it could slide out from under you.
•The brake pads could get wet when you wash the scooter. After washing the scooter check the brakes
before riding.
•Always wear a helmet gloves trousers (tapered around the cuff and ankle so they do not flap) and a
bright colored jacket.
•Do not carry too much luggage on the scooter. An overloaded scooter is unstable.
