2. The tires should be set to the recommend-
ed pressure:
G
Recommended tire pressure
Front 27.5 kPa (0.275 kgf/cm
Rear 27.5 kPa (0.275 kgf/cm
G
Check and adjust tire pressures when the
tires are cold.
G
Tire pressures must be equal on both
sides.
3. Tire pressure below the minimum speci-
fied could cause the tire to dislodge from
the rim under severe riding conditions.
The following are minimums:
Front 24.5 kPa (0.245 kgf/cm
Rear 24.5 kPa (0.245 kgf/cm
4. Use no more than the following pressures
when seating the tire beads.
Front 250 kPa (2.5 kgf/cm
Rear 250 kPa (2.5 kgf/cm
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.
