The 2023 KTM 390 Duke Is An Excellent Entry Level Naked Bike

KTM’s 2023 model lineup certainly wouldn’t be complete without a handful of Duke naked bikes, and the European manufacturer didn’t disappoint. Coming just shy of the smallest KTM available for purchase is the 2023 390 Duke, which shares its powerplant with its fully-faired brother: the RC 390. While this entry-level naked bike is small in stature, it certainly isn’t a slouch, featuring competitive power, excellent handling, and KTM-level refinement, all with a starting price under $6,000 USD.

This little rocket features a single-cylinder engine, making a claimed 44hp and 27 lb-ft of torque. Weighing in at just 328 lbs (dry), this naked-sport shouldn’t have any trouble getting up to speed. While many riders shy away from entry-level bikes because they are afraid of looking like a giant, that shouldn’t be a worry here, the 390 Duke sits with a seat height of 32.3 inches – less than an inch shorter than the full-sized 890 Duke and making it approachable for riders of all sizes.

KTM’s motto is “Ready To Race”, and while the 390 Duke may not appear to be the most track-ready machine on the market, or even in KTM’s lineup, it’s clearly taken cues from the RC16 bike currently being ridden by Jack Miller and Brad Binder in MotoGP. For starters, the 390 comes standard fitted with features like adjustable rear suspension, a slipper clutch, and a suite of rider aids. ABS is standard, and the bike even gets a “supermoto mode” which disables ABS in the rear to allow for some tire sliding around corners. Sounds like a blast.

Euro bikes are known for their flare just as much as their performance, and this little Duke is no exception – an aggressive LED headlight is the focal point of the front of this bike, with sharp lines carrying all the way back past the 3.5-gallon fuel tank to the pillion seat. The 390 Duke is available in either black or grey, both with a KTM orange frame.

The 2023 KTM 390 Duke starts at $5,899 USD / $6,599 CAD.

2023 KTM 390 Duke Features


The KTM 390 DUKE engine not only delivers arm-wrenching torque and hair-raising acceleration, but also good manners in everyday use, all with outstanding fuel economy. This lightweight, compact engine really packs a punch and with 32 kW (44 hp) it’s one of the most powerful options out there for A2 riders. Thanks to the ingenious intake design and the meticulous fuel injection system, the KTM 390 DUKE is ready and waiting to tear-up the streets and the circuits alike.


The KTM 390 DUKE comes as standard with ultra-lightweight, high-performance upside-down WP forks. Using the latest open-cartridge technology, these forks not only perform above expectations when pushed to the limits, but are also nice and easy to maintain. This makes them perfect for all aspects of riding, from relaxed cruising to hammering around on closed circuits and everything in between.

Shock absorber

Thanks to its progressive 150 mm spring, the KTM 390 DUKE will perform in any environment you can throw at it. The preload is adjustable, so you can count on well-balanced suspension whether you’re riding solo or two-up, with or without luggage, on road or on track. The choice is yours.


As light as they are stable, the 17-inch cast alloy racing wheels help you put the power down with confidence, utilizing a 110 mm wide tire at the front and an impressive 150 mm at the rear. Wrapped in premium rubber, the pro-spec tires will keep your KTM 390 DUKE glued to the road. They offer outstanding grip in both wet and dry conditions, as well as providing supreme durability, even for riders that know how to push tires to their absolute limits.


A high-tech BYBRE braking system works in perfect harmony with the advanced ABS, providing riders with firm, controlled stopping power when they need it most. With a 320 mm brake disc on the front, paired with a 230 mm disc on the rear, the KTM 390 DUKE delivers exceptional pro-level stopping power, and you know what they say: “braking harder makes you faster!”

Fuel tank

The innovative and ergonomic 13.4 liter (3.5 gal) steel fuel tank not only provides riders with perfect knee contact for attacking every corner, but also with an unbelievably long range, even when you ride as fast as you dare all day long.


The two-part seat offers first class sport riding ergonomics with perfect support for both rider and pillion.  A seat height of 820 mm (32.3 in) enables riders to have a super-secure position, whilst also being high enough for ultimate cornering fun. The pillion seat has been integrated into the bodywork so as not to compromise the stunt-ready look of the KTM 390 DUKE, whilst also ensuring excellent comfort for the passenger.


Hi-tech upright handlebars offer KTM 390 DUKE riders a controlled yet aggressive body position, allowing you to dominate in all aspects of riding. From destroying corners to pulling the perfect stoppie, these bars will give you the balance and confidence you need to attack the road like never before. Clutch and brake levers are fully adjustable, allowing you to customize your cockpit to suit your individual riding style.

TFT color dashboard

As an absolute first in its class, the KTM 390 DUKE boasts an innovative multicolor TFT display, presenting all the data you need to go faster in a clear-cut, uncluttered way. As you rev the engine, the display bars change color, either spurring you on or telling you to back off when the engine’s still cold. The display also automatically adapts its color to best suit the light conditions around you. Innovation at its best!!!
