Additional Notes
- The Honda NM4 Vultus cooling system holds 1.69 liters of coolant, which is a typical fill volume for a mid-displacement liquid-cooled parallel-twin motorcycle engine.
- Both the 670 cc and 745 cc engine variants share an identical coolant capacity of 1.69 liters, indicating the cooling system architecture is consistent across displacement configurations.
- The coolant check interval is set at 12,800 km under normal use conditions, which aligns with standard periodic inspection schedules for motorcycle cooling systems.
- Coolant changes are specified on a 36-month cycle rather than a mileage-based interval, reflecting the time-dependent degradation of coolant additives such as corrosion inhibitors and pH stabilizers.
- The time-based change interval of 36 months applies equally to both the 670 cc and 745 cc variants, with no differentiation in service frequency between the two engine displacements.
