Additional Notes

  • The KTM 390 Duke cooling system capacity across the 2013-2014 model years is 1.1 liters, while the 2015-2023 models share a slightly larger 1.2-liter capacity, and the 2024 model returns to a reduced 1.0-liter figure.
  • The 2013-2014 service interval is expressed as a check at 7,500 km or 12 months, whichever comes first. A check interval differs from a change interval in that coolant condition and level are inspected rather than the fluid being automatically replaced.
  • From 2015 onward, the service action shifts from a periodic check to a full coolant change on a 48-month interval. A 48-month change cycle is a time-based replacement schedule independent of mileage accumulation.
  • The 1.2-liter cooling system capacity applies across a notably wide span of model years, covering 2015-2023, which reflects the same basic liquid-cooled single-cylinder engine architecture across those generations.
  • The 2024 model's 1.0-liter cooling system capacity is the smallest figure listed across all years in the specifications, representing a reduction of 0.2 liters compared to the 2015-2023 figure.
  • All rows carry a normal use condition, meaning none of the listed capacities or intervals are adjusted for severe operating conditions such as extreme heat, dusty environments, or frequent short-trip riding.
  • The 2013 and 2014 rows each carry identical specifications despite being listed as separate entries, both showing a 1.1-liter capacity with a check interval of 7,500 km or 12 months under normal use.
