SAFE-RIDING AND SAFETY POINTS
Motorcycles are convenient vehicles; you should always keep the motorcycle in the perfect conditions to make sure
that you can ride it safely. What's more, the rider must always be at their best mental and physical status. Riding under
the influence of medication, drugs and alcohol is, of course, prohibited. (Under the influence of even a small amount of
alcohol, the rider is more likely to put him/herself in extremely dangerous conditions.)
Protective clothing is as essential to the motorcycle riders as seat belts to car drivers and passengers. Always wearing
a proper motorcycle suit, gloves and helmet will protect rider from being hurt. Note: Some riders with protective clothing
may have illusions of total safety and protection, and they will run the risk of going too fast and are apt to take chances,
facing even greater dangers in wet weather. Good motorcyclists will always have his/her wits about this situation
besides the traffic rules.
Enjoy your ride!

Turn right
1.Be sure to signal clearly in the fol-
lowing situations:
2.Braking can be extremely difficult on
a wet road. Avoid hard braking, since
the motorcycle may slide. Apply the
brakes slowly when stopping on a wet
surface.
3.Slow down when approaching a cor-
ner or turn, and accelerate slowly once
the turn has been completed.
4.Be careful when passing parked cars.
The driver might have not seen you and
open the door in a sudden.
5.Railroad crossings, streetcar rails, iron
plates on road construction sites, and
manhole covers will become extremely
slippery when wet. Slow down and cross
them with caution. Keep the motorcycle
upright, otherwise you may fall from the
motorcycle.
6.The brake pads could get wet when
you wash the motorcycle. After wash-
ing the motorcycle, check the brakes
before riding.
7.Always wear a helmet, gloves, trou-
sers (tapered around the cuff and ankle
so they would not flap), and a bright
color jacket.
8.Do not carry too much luggage on
the motorcycle. Overloaded motor-
cycles are unstable. Please secure the
luggage to the rear rack with a firm
rope. Unfastened luggage will affect
the stability of the motorcycle and di-
vert your attention from the road
condition.
9.When riding the motorcycle in the
littoral, since the salinity in the air is
higher, this will speedup the corrosion
of the iron parts, you should wash the
motorcycle more frequently.
