This nameplate marks KTM’s return to the 990-class middleweight naked bike segment, introduced for the 2024 model year as an all-new streetfighter positioned above the 790 and below the larger Super Duke family. It is not a continuation of an earlier 990 Duke model but a fresh modern entry that uses KTM’s current parallel-twin platform and a completely new chassis and electronics package. KTM has kept it in production through the 2025 and 2026 model years, and it continues into the current lineup, so there is no confirmed end year to record.
In KTM’s Duke family, this model sits as the core performance-oriented road bike for riders who want sharper handling and a more aggressive character than the smaller Duke models, but without moving into the extreme upper echelon of the Super Duke range. Its launch also helped re-establish the 990 displacement number in KTM road bikes after years in which that designation was absent from the lineup. The bike’s history is therefore best understood as a modern revival of the 990 badge in a new-generation form rather than a long-running carryover of an older machine.
For enthusiasts, the importance of this model lies in the way KTM used it to reset the middle of its naked-bike range: new styling, new architecture, and a more focused street performance brief, while retaining the Duke family’s reputation for agile, minimalist sport riding. It has also served as the basis for a separate higher-spec Duke R variant, reinforcing the 990 platform as a key part of KTM’s contemporary road lineup.
