The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Aerox R 4T, NS50F (2014-2020)
  • Use: Normal
  • Capacity 0,52 liter (Radiator)
  • Capacity 0,26 liter (Reservoir)
  • Change 36 months

Additional Notes

  • The Yamaha NS Aerox R cooling system carries a total split capacity across two separate volumes: 0.52 liter for the radiator and 0.26 liter for the reservoir, giving a combined figure of 0.78 liter when both are filled.
  • The radiator capacity of 0.52 liter reflects the primary circuit volume, which is the portion of the cooling system that circulates coolant directly through the engine and radiator core under normal operating pressure.
  • The reservoir holds 0.26 liter, representing exactly half the radiator volume. The reservoir functions as an overflow and expansion tank, accommodating coolant displaced by thermal expansion during engine operation.
  • A 36-month change interval applies to the Aerox R 4T, NS50F across the 2014-2020 model years under normal use conditions, meaning the coolant is rated for a three-year service life in standard riding environments rather than shortened intervals associated with severe use.
