KTM North America announced it is bringing the updated 390 Duke and 250 Duke to the U.S. and Canada, bolstering its naked lineup for these markets. Both Singles were announced in other markets over the summer, along with an updated 125 Duke, but it’s now official that the 390 and 250 will be coming to North America.

Both models are all new, replacing the previous generation 390 Duke and 200 Duke, respectively, with new engines, new two-piece frames, updated styling, plus other updates.

The bodywork is even more aggressive-looking than the previous design, and a new headlight with LED daytime running lights now surrounding the main headlight.

The 2024 390 Duke is powered by a new 399cc DOHC Single dubbed the LC4c, offering a larger displacement than the 373cc powerplant in the previous generation model, as well as the 390 Adventure and RC 390.

KTM claims a peak output of 44.3 hp at 8,500 rpm and 28.8 lb-ft. at 6,750 rpm, which is an increase compared to the 373cc version which was certified with an output of 42.9 hp at 9,000 rpm and 26.6 lb-ft. at 7,000 rpm.

The chassis is a new two-piece design, combining a new steel trellis main frame and a die-cast aluminum subframe. KTM says this combination augments torsional rigidity, while improving agility and providing more feedback. The new triple clamps have a revised offset, with KTM claiming improved control and stability.

The front suspension remains the same 43mm WP APEX open cartridge inverted fork as the 2023 model, offering a five-click adjustment on rebound and compression. The rear suspension is a similar WP APEX monoshock with adjustable preload and rebound as the previous model, but it has been repositioned off-center to make room for a larger airbox. This also required a new curved swingarm design. An added benefit of the repositioned shock and new subframe is a 32.3-inch seat height, compared to the previous 32.7-inch height. The height can further be lowered to 31.4 inches by removing a seat spacer.

The front wheel is equipped with a single four-piston radial caliper with a 320mm disc, while the rear wheel comes with a single-piston floating caliper and 230 mm disc. A Bosch 9.1MP Two-Channel cornering ABS comes standard, as does the selectable Supermoto ABS mode that disables the cornering function, turns off rear wheel ABS, and deactivates rear wheel lift prevention.

The 2024 390 Duke comes with three selectable ride modes. The Street and Rain modes from the previous generation return, joined by a new track mode. The new mode enables launch control while altering the display on the new 5” TFT screen to show an enlarged tachometer.

The TFT display offers smartphone connectivity for playing music, answering calls or providing turn-by-turn navigation. Infotainment functions are controlled via new switchgear with a four-way menu switch.

Other updates include a new fuel tank, new forged aluminum footpeg hangers,self-cancelling turn signals, and a claimed curb weight of 363.7 pounds.

The 2024 KTM 390 Duke will be available in U.S. showrooms in December with a choice of Signature Electronic Orange or Atlantic Blue. Pricing remains to be announced.

The 2024 KTM 250 Duke shares many of the same components as the 390, but with a few notable differences.

The engine is a smaller 249cc Single, with just a single overhead cam (SOHC), claiming a peak output of 30.8 hp. The engine is joined by a six-speed transmission, along with a PASC slipper clutch.

The suspension system consists of a 43mm WP APEX Open Cartridge fork and WP APEX Emulsion rear shock, all non-adjustable except for rear preload. The braking system is the same as the 390, including Cornering ABS with Supermoto ABS mode.

The 250 Duke also comes with a smartphone-compatible 5” TFT and a ride-by-wire throttle, but without selectable ride modes. The LED headlight also lacks the 390's separate daytime running lights.

Other features include a steel tapered handlebar (instead of aluminum as on the 390 Duke), and the lowered 31.4-inch seat height as standard.

The KTM 250 Duke is expected to arrive in early 2024, with a choice of Electronic Orange or Ceramic White colors. U.S. pricing has not been released.

    How many displacements does KTM need? Starting to become a joke. At least they introduced the option to reduce the seat height on this beginner bike.
