This vehicle is equipped with inner tube
tires.

WARNING
Check the tire inflation at room temper-
ature at least once a week, see p. 94
(TECHNICAL DATA).
Pressure measurement must always be
carried out when the tires are cold, as
when the tires are warmed up, pressure
will increase, and if they are checked at
this time erroneous readings will be seen.
If the tire is inflated to too high a pres-
sure, an uncomfortably harsh ride will
result, and riding comfort will be com-
promised. Also, road holding, especial-
ly during turns and in wet conditions,
will likewise be compromised.
If the tire is underinflated (pressure is
too low), the tire may slip on the rim
with consequent loss of control. Again,
road holding and handling characteris-
tics will be degraded, and brake perfor-
mance will be reduced.
When the tire is worn to a point where
any tread is less than 0.12 in (3 mm)
deep, the tire is worn out, and must be
replaced. Also, if a tire suffers a punc-
ture that is larger than 0.20 in (5 mm) in
its longest dimension, the tire must not
be repaired, but should be replaced.
After a tire is repaired, balance the
wheels. Use only tires that are listed.

use and maintenance Scarabeo 50
Install only tires that are listed in the
technical data, see p. 94 (TECHNICAL
DATA), or that have been specifically
approved by APRILIA for this vehicle.
a
The use of tires other than those ap-
proved by APRILIA may adversely effect
the handling of the vehicle, leading to
an upset and accident, with subsequent
serious injury or even death.
Ensure that valve caps are installed on
all tires. This is important to prevent
sudden flats.
Do not ride the vehicle if the tire wear in-
dicators show that the tire is worn out.
Failure to heed this warning can lead to
an accident with subsequent serious in-
jury or even death.
Some types of tires homologated for this
vehicle are provided with wear indicators.
There are several kinds of wear indicators.
For more information on how to check
the wear, contact your Dealer.
Visually check if the tires are worn and
in this case have them changed.
If a tire should go flat while you are
riding the vehicle, do not attempt to
continue riding. Avoid abrupt braking
and steering inputs, and avoid shutting
the trottle quickly. Slowly decrease the
throttle setting, moving to the side of
the road, using the engine compression

to slow you to a stop. Non-compliance
with these instructions may cause acci-
dents with consequent risk of injuries
or even death.
If the tires are very old, even if they are
not completely worn out, they may have
become so hard that road holding is com-
promised. In this case, replace the tires.
Do not install tires with inner tube on
rims for tubeless tires and viceversa.
Repair, maintenance, changing and bal-
ancing of tires are very important to
your safety, and should only be per-
formed by qualified mechanics using
the appropriate tools.
For this reason, we suggest that you
have your tires serviced by your Local
APRILIA Dealer.
a
WARNING
New tires are often covered with a slip-
pery mold release compound. Scrub
the tires in by riding slowly and making
numerous turns for the first few miles.
Do not use any kind of tire dressing or
other liquid on your tires. Especially do
not permit any petroleum products,
such as oil, gasoline or brake fluid to
come in contact with the tires. If you
do, wipe it immediately, then scrub the
tire with soap and water and a stiff
brush. Do not use a tire that is worn
out.
Minimum tread depth is measured as
