Additional Notes

  • The KTM 790 Adventure cooling system holds 1.6 liters across all listed variants, a capacity consistent with a liquid-cooled parallel-twin engine of this displacement class where the circuit covers the engine block, cylinder head, and radiator.
  • The 790 Adventure and 790 Adventure R share identical cooling system capacities of 1.6 liters, indicating no meaningful difference in the cooling circuit volume between the standard and off-road-oriented R variant.
  • The 790 Adventure R Rally, produced for 2020-2021, carries the same 1.6-liter cooling system capacity as the broader 790 Adventure lineup, placing the Rally variant within the same engine and cooling architecture.
  • A 48-month change interval applies to all listed variants under normal use conditions. A time-based interval of this length reflects the degradation rate of coolant additives, particularly corrosion inhibitors, which break down over time regardless of mileage accumulation.
  • The 790 Adventure introduced from 2022 onward retains the same 1.6-liter capacity and 48-month change interval as the 2019-2021 model, indicating no revision to the cooling system specification between those generations.
