EBU19761 pressure below the minimum specified could also cause the tire to dislodge from the rim under severe riding conditions. [EWB02541] Set tire pressures to the following specifications: Recommended tire pressure: Front 25.0 kPa (0.250 kgf/cm², 3.6 psi) Rear 25.0 kPa (0.250 kgf/cm², 3.6 psi) Minimum tire pressure: Front 22.0 kPa (0.220 kgf/cm², 3.2 psi) Rear 22.0 kPa (0.220 kgf/cm², 3.2 psi) Maximum tire seating pressure: Front 250 kPa (2.5 kgf/cm², 36 psi) Rear 250 kPa (2.5 kgf/cm², 36 psi) The low-pressure tire gauge is included as standard equipment.
