Vehicle Information
KTM 790 Duke Motorcycle - Street (2018-2024)
The KTM 790 Duke, affectionately known as "The Scalpel," carved out a significant niche in KTM's lineup from 2018 to 2024. This aggressive naked bike is powered by a consistent 799cc LC8c parallel-twin engine across all model years. Initially launched in 2018 (for the US market), it delivered 105 hp for most regions, with a 95 hp "790 Duke L" version available in Europe for A2 license holders. A notable shift occurred in 2021 when the 790 Duke was largely phased out due to stricter Euro 5 emissions standards, making way for the 890 Duke. However, it made a strategic comeback in 2022, facilitated by a production partnership with CFMoto. This reintroduction saw the 790 Duke retain its original 799cc engine and 105 hp output (with the 95 hp A2 version still offered in Europe), positioning it as an accessible middleweight option. The model continued with these core characteristics through 2024, with potential cosmetic updates and component changes anticipated for future iterations beyond this range.
