CHECK TIRE PRESSURE.
STANDARD TIRE PRESSURE
One passenger Two passengers
Front 20 psi/1.4 bar
Rear 26 psi/1.8 bar
Inflation pressure should be checked when the tires are cold. The tires are considered "cold"
when they have the same temperature as the surrounding (ambient) air. This temperature is
normally reached after the scooter has been parked for at least three hours. After driving a
distance of approximately 1 km, the tires are considered "hot". If you have to drive further than
this distance to pump your tires, check and record the tire pressure first and add the appropriate
air pressure when you get to the pump. If checking tire pressure when the tire is hot, never
"bleed" or reduce air pressure. The tires are hot from driving and it is normal for pressure to
increase above recommended cold pressures. A hot tire, at or below recommended cold inflation
pressure could be significantly under-inflated.
24 psi/1.7 bar
32 psi/2.2 bar
