Additional Notes

  • The Honda NS 400 R carries a coolant capacity of 1.9 liters for the cooling system, which represents a full system fill volume typical of a liquid-cooled two-stroke engine of that displacement class.
  • Under normal use conditions, the NS 400 R cooling system specifies a coolant change interval of 24 months, reflecting a time-based service schedule rather than a mileage-based one.
  • The 1.9-liter capacity applies uniformly across the 1985-1988 production span of the NS 400 R, with no variation recorded between model years within that range.
