2023 KTM 390 Duke

The 2023 KTM 390 Duke is a lightweight street bike that packs a surprising amount of performance into a compact, aggressive package. With its sharp styling, punchy single-cylinder engine, and nimble handling, the 390 Duke is a great fit for riders who want something that's easy to ride around town but still has plenty of personality when the road starts to get twisty.
Power comes from KTM's 373cc liquid-cooled, single-cylinder four-stroke engine, producing around 44 horsepower. The engine delivers strong low- and mid-range torque while still being happy to rev, giving the Duke an energetic feel without making it overwhelming for newer riders. Its six-speed transmission gives you plenty of flexibility, whether you're commuting through traffic or enjoying a weekend ride.
One of the biggest strengths of the 390 Duke is its lightweight chassis and responsive handling. The steel trellis frame keeps the bike compact and helps give it that quick, agile feel KTM is known for. At roughly 330 pounds ready to ride, the Duke is easy to maneuver at low speeds and feels lively when you're carving through corners. The upright riding position also gives you a good view of traffic while keeping the bike comfortable enough for everyday riding.
Suspension comes from WP components, with an inverted front fork and rear monoshock designed to balance sporty handling with everyday usability. The suspension gives the bike a planted feel through corners while still handling bumps and imperfect pavement reasonably well.
Stopping power comes from Brembo-owned ByBre brakes, including a four-piston front caliper and rear disc brake. Bosch cornering ABS adds another layer of confidence, helping provide controlled braking performance while allowing the rider to enjoy the bike's sporty character.
The 390 Duke also comes with a useful collection of modern electronics. Ride-by-wire throttle control, multiple ride modes, traction control, and a color TFT display help give the bike a more premium feel than you might expect from a lightweight motorcycle. The electronics can be adjusted to suit different riding conditions, while the TFT display keeps important information easy to see.
Styling is unmistakably KTM, with sharp bodywork, an exposed trellis frame, angular LED lighting, and an aggressive streetfighter appearance. The compact proportions and minimal bodywork give the Duke a purposeful look while also making it easy for the rider to move around on the bike.
Whether you're looking for a fun commuter, a first performance-oriented motorcycle, or simply a lightweight bike that's entertaining on a back road, the 2023 KTM 390 Duke checks a lot of boxes. It's quick, lightweight, economical, and packed with technology, making it a motorcycle that's just as comfortable navigating the city as it is attacking a winding road.
