Additional Notes
- The KTM 1390 Super Duke R and 1390 Super Duke R EVO share an identical cooling system capacity of 3.2 liters, which reflects a full system fill volume rather than a partial service top-up.
- A 3.2-liter coolant capacity is relatively substantial for a motorcycle, consistent with the demands of a high-displacement, high-performance liquid-cooled engine.
- Both the 1390 Super Duke R and 1390 Super Duke R EVO specify a coolant change interval of 48 months under normal use conditions, meaning standard riding environments without the added stress of extreme heat, track use, or harsh climates.
- The 48-month interval is a time-based specification rather than a mileage-based one, so elapsed calendar time governs the service schedule regardless of how many kilometers have been accumulated.
- The cooling system specifications for the 1390 Super Duke R and 1390 Super Duke R EVO introduced from 2023 are identical across both variants, indicating no differentiation in cooling system design between the standard and EVO configurations.
