The KTM 390 DUKE has big features in a smaller package. Aggressive styling proclaims that the 390 DUKE is a READY TO RACE naked motorcycle with performance and handling to back it up. The bodywork is sharp and modern with a slammed, predatory stance.  Up font a LED headlight and bright, full-color TFT digital dash boast features not found in this class of motorcycle. At the rear the exposed bolt-on subframe sits below the redesigned seat and pillion. A form-fitting 3.5 gallon steel fuel tank increases the 390 DUKE’s range.   

Underneath the aggressive look, a compact DOHC 373cc single pumps out class-leading power and torque for a ride that only a DUKE can provide. Putting the power to the ground is smooth and controllable thanks to the ride-by-wire throttle. That power combined with a steel trellis frame, a 43mm WP upside-down fork and a larger, more powerful 320mm front brake rotor take the ride to the next level. The 2018 KTM 390 DUKE is truly a corner rocket.
