At the heart of the KTM 390 Duke lies a 399cc, single-cylinder, liquid-cooled, DOHC engine that delivers a robust 46 PS @ 8500 rpm and 39 Nm of torque @ 6500 rpm. This powerplant is paired with a 6-speed gearbox featuring an assist & slipper clutch and a quick shifter, allowing lightning-fast gear changes without clutch use.
The bike’s high compression ratio of 12.71:1 and Bosch EFI system ensure crisp throttle response and efficient fuel delivery, making it equally capable in stop-and-go city traffic or open highways.
