Tire air pressure (measured on
cold tires)
Front
100 kPa (1.00 kgf/cm², 15 psi)
Rear
100 kPa (1.00 kgf/cm², 15 psi)
TIP
• Check the tire while it is cold.
• Because if the bead stopper tightening nut is
loose when the tire pressure is low, the tire
could slip off the rim, thus be sure to check and
tighten the bead stopper tightening nut "a".
• If the tire valve stem "b" is found tilted, the tire
is considered to be slipping off its position. Cor-
rect the tire position.
