Additional Notes
- The KTM 990 Duke cooling system holds 1.77 liters of coolant, a figure that reflects the total system fill volume rather than a partial or overflow-only quantity.
- The 48-month change interval applies under normal use conditions, meaning standard riding environments without the added thermal and contamination stress associated with severe use classifications.
- A 48-month coolant service interval is relatively extended compared to many motorcycle cooling systems, which is consistent with modern long-life coolant formulations that resist degradation and corrosion over multi-year periods.
