Jump to Full Specifications ↓First Impressions & Ride Summary
The 790 Duke instantly feels like an extension of your body — incredibly light, flickable and responsive. The parallel twin delivers smooth torque off idle that builds to an exhilarating top-end rush. It’s playful but disciplined — a naked that thrives on precision.
From urban rides to fast twisties, the 790 offers balance and feedback rarely found in this segment. KTM didn’t exaggerate calling it “The Scalpel.”
Design & Ergonomics
The 790 channels KTM’s aggressive design language with clean, minimalistic bodywork and an exposed trellis frame. The twin-headlight / sculpted tank combo and compact tail give it a pure streetfighter attitude.
Ergonomically it’s neutral and confidence-inspiring — seat height at 825 mm and upright bars make it comfortable for daily use while remaining ready for spirited cornering.
Engine & Performance
The 799 cc parallel twin is compact and torquey — producing between 95–105 PS depending on market, with 87 Nm @ 8,000 rpm. Power delivery is linear, sharp and usable, giving a thrilling midrange and an eager top end.
Transmission is a 6-speed with quickshifter and slipper clutch; throttle mapping and ride modes make it adaptable from relaxed commute to aggressive canyon work. The exhaust note is mechanical and rewarding through the rev range.
Handling & Chassis
Handling is where the 790 earns its nickname — “The Scalpel.” The chromoly trellis frame and WP suspension deliver razor-sharp turn-in, precise mid-corner balance and confidence when you push the pace.
Despite its punch, the 790 feels light and intuitive. Wheelbase of 1475 mm and ground clearance of 186 mm combine for a stable yet agile platform.
Braking
Stopping duties come from twin 300 mm front discs with 4-piston radials and a 240 mm rear disc, paired with lean-sensitive cornering ABS and Supermoto mode. Lever feel is progressive and powerful, allowing precise control during spirited riding.
The electronics are well-integrated — they help keep things safe while preserving the bike’s dynamic character.
Owner Experience & Community Opinion
Riders praise the 790 for its lightweight handling and daily usability. It’s easy to ride fast, flickable through corners and practical enough for commutes. Many owners call it the perfect midpoint between the nimble 390 and the ferocious 1290 Super Duke R.
