Vehicle Information
KTM 390 Duke Motorcycle - Street (2015-2026)
The KTM 390 Duke, an agile and high-performance naked street bike, was produced from 2015 to 2026. Renowned for its nimble handling and single-cylinder engine, it established itself as a benchmark in its category. Initially powered by a 373 cc engine producing around 43-44 horsepower, it underwent continuous evolution. A significant mid-cycle update occurred in 2017, introducing an LED headlight, a TFT display, a ride-by-wire system, and a larger fuel tank. However, the true generational break arrived in 2024. This new model, considered 90% new, featured a more powerful 399 cc LC4c engine (around 45 hp), a completely redesigned chassis, adjustable suspension, and advanced electronic aids like cornering ABS and traction control. Throughout this period, the 390 Duke was offered as a single model, without distinct trim levels. FAQ:
