Ktm 790 Duke
The KTM 790 Duke was introduced in 2018 as a mid-displacement naked streetfighter, earning the nickname 'The Scalpel' for its razor-sharp handling and lightweight chassis. It was notable for debuting KTM's all-new parallel-twin LC8c engine platform, filling the gap between the 690 Duke and 1290 Super Duke R. The 790 Duke won widespread acclaim for its class-leading power-to-weight ratio and cornering performance, though it was eventually superseded by the 890 Duke in 2021.

What Buyers Should Know
LC8c Engine Strength
The parallel-twin LC8c engine is praised for its smooth power delivery and longevity when properly maintained. Regular valve checks every 15,000 km are essential to keep it running reliably.
Watch for Recalls
Early 2018-2019 models had known issues with throttle body software and occasional stalling at low speeds. Always verify the VIN has received all KTM service bulletins before buying used.
Strong Resale Value
The 790 Duke holds its value well due to its cult following and the fact that KTM discontinued it in favor of the 890, making clean examples increasingly desirable and sought after.
