Tire pressure
EWA14960
WARNING
• Tire pressure below the minimum specifi-
cation could cause the tire to dislodge
from the rim under severe riding condi-
tions. The following are minimums:
• Front
24.5 kPa (0.25 kgf/cm
• Rear
24.5 kPa (0.25 kgf/cm
• Use no more than the following pressures
when seating the tire beads.
• Front
250 kPa (2.5 kgf/cm²) (36 psi)
• Rear
250 kPa (2.5 kgf/cm²) (36 psi)
Higher pressures and fast inflation may
cause a tire to burst. Inflate the tires very
slowly and carefully.

WARNING
Uneven or improper tire pressure may
adversely affect the handling of this vehicle
and may cause loss of control.
• Maintain proper tire pressures.
• Set tire pressures when the tires are cold.
• Tire pressures must be equal in both front
tires and equal in both rear tires.
2. Check:
• Tire surfaces
