The KTM 390 Duke takes the strengths of the 250 Duke and amplifies them. Boasting a more powerful 373.2cc single-cylinder engine, the 390 Duke offers significantly more performance, making it capable of quicker acceleration and higher top speeds. Despite the increased power, it retains the sharp handling and agile characteristics of its smaller sibling. Furthermore, the 390 Duke often incorporates more advanced features, such as ride-by-wire throttle and sophisticated rider aids like traction control, further enhancing safety and rider experience. Its design is similarly aggressive and modern, often featuring upgraded components like higher-specification brakes and suspension. While slightly more expensive than the 250 Duke, the 390 Duke delivers a significant upgrade in performance and features, making it an attractive option for riders seeking a more powerful and feature-rich motorcycle.
