  • The KTM 790 Duke cooling system capacity increased from 1.2 liters in the 2017-2021 configuration to 1.6 liters in the 2022 configuration, representing a 0.4-liter difference between the two generations.
  • The 2017-2021 790 Duke carries a coolant change interval of 24 months under normal use conditions.
  • The 2022 790 Duke doubles the coolant change interval to 48 months under normal use conditions, compared to the 24-month interval of the earlier generation.
  • The 2022 EU variant of the 790 Duke shares identical cooling system specifications with the standard 2022 configuration, with a 1.6-liter capacity and a 48-month change interval under normal use conditions.
  • A coolant capacity of 1.6 liters is a full cooling system service fill figure, meaning the value reflects the total volume required when the system is drained and refilled completely.
