Tires
We recommend that you visually check
your tires before every ride and use an air
pressure gauge to measure the air pressure
at least once a month or any time you
think the tires might be low. Even tires
that are in good condition may lose one to
two psi per month if not checked and
adjusted regularly.
Tubeless tires have some degree of self-
sealing ability if they are punctured.
However, because leakage is often very
slow, you should look closely for
punctures whenever a tire is not fully
inflated.
Always check air pressure when your tires
are ''cold'' –– after the scooter has been
parked for at least three hours. If you
check air pressure when your tires are
''warm'' –– even if your scooter has only
been ridden for a few miles –– the

readings will be higher. If you let air out
of warm tires to match the recommended
cold pressures, the tires will be
underinflated.
The recommended ''cold'' tire pressures
are:
25 psi
front
(175 kPa , 1.75 kgf/cm )
29 psi
rear
(200 kPa , 2.00 kgf/cm )
with less than 200 lbs
(90 kg) of added weight
36 psi
(250 kPa , 2.50 kgf/cm )
with more than 200 lbs
(90 kg) of added weight
