This is an old post, but I think I've accidentally deleted it. So I decided to write it again to remind me the ideal tire pressure for all scooter and small sized motorcycle.
According to the manual book, the ideal tire pressure is:
* 1 rider
Front: 1.75 kg/cm2
Rear: 2.00 kg/cm2
* 2 riders
Front: 1.75 kg/cm2
Rear: 2.25 kg/cm2
* 2 riders (GD250)
Front: 2.00 kg/cm2
Rear: 2.25 kg/cm2
If we convert it into PSI (1 kg/cm2 = 14.223 psi), then the tire pressure is:
* 1 rider
Front: 1.75 * 14.223 psi = 24.89025 psi
Rear: 2.00 * 14.223 psi = 28.446 psi
* 2 riders
Front: 1.75 * 14.223 psi = 24.89025 psi
Rear: 2.25 * 14.223 psi = 32.00175 psi
* 2 riders (GD250)
Front: 2.00 * 14.223 psi = 28.446 psi
Rear: 2.25 * 14.223 psi = 32.00175 psi
