KTM has given the 790 Duke its most comprehensive refresh since the model first arrived in 2018, aiming to sharpen handling and daily usability without stripping away the bike’s trademark edge. The 2026 update brings new styling, revised ergonomics, upgraded suspension and brakes, a new TFT screen and a raft of small changes intended to make the middleweight more versatile on the road.
What’s changed for 2026
The revision keeps the same headline numbers—about 105hp and roughly 87Nm (64lb‑ft)—but touches nearly every component. KTM fitted a lighter subframe, redesigned bars and footpeg positions, a new exhaust and revised ergonomics. Rear-wheel travel increases by 20mm and the seat is broader and more supportive.
Electronics receive a notable update: a new colour TFT display, improved switchgear and four riding modes. Cruise control now comes as standard, while a quickshifter remains optional or bundled in a Tech Pack.

First impressions
Visually the Duke is sharper and more aggressive, moving the look closer to KTM’s current family style. Proportions remain compact; the bike still reads as ready to pounce.
Climbing on, riders notice a slimmer waist and easier floor reach despite an unchanged seat height. Handlebars are straighter, encouraging a more assertive stance, and the new bar risers can be flipped for a slightly more relaxed position. Small changes to peg placement—7mm further back and 2mm higher—nudge the ergonomics toward a sportier feel without making the bike uncomfortable for everyday use.
On the road
Riding around the Austrian Alps, the updated chassis feels perkier and more willing to change direction. KTM’s modest 2kg weight reduction is tangible; the bike turns with less effort and rewards an active riding style.
The revised WP suspension is the biggest contributor to that composure. With longer rear travel and adjustable fork and shock, the standard settings balance support and comfort well. Rough surfaces are absorbed more kindly now, yet the bike remains lively and communicative through corners.
The engine hasn’t been radically altered, but throttle response is smoother at low speeds and less abrupt than earlier 790s. There’s still strong midrange shove that keeps the Duke engaging on fast roads, though the very top end remains a touch limited compared with some rivals.
Tech and usability
The new TFT display is a step up: readable in bright light and quick to navigate. Riders get four modes—Rain, Street, Sport and Track—with Street and Sport covering most everyday needs. Track mode is highly interventionist and better suited to closed circuits than public roads.
Cruise control is now standard. The quickshifter generally works well, but the test revealed occasional hesitation in low‑gear upshifts and a few false neutrals under heavy use—issues to be aware of for riders who change gear frequently.
WP brakes steal the show
Arguably the headline mechanical change is the switch to WP‑developed braking hardware. KTM has replaced the previous setup with in‑house WP calipers and master cylinders, pairing twin four‑piston front calipers with 300mm discs and a 240mm rear disc.
The result is unexpectedly accomplished. Lever progression lets you meter force precisely while trail braking. The bite firms up predictably as you compress harder, and outright stopping power is strong and immediate. Reach adjustment on the levers is almost stepless, which helps riders with smaller hands find a comfortable position quickly.
Pros and cons
- Pros: Superb new WP brakes with a premium feel; sharper handling without losing comfort; improved day‑to‑day refinement.
- Cons: Quickshifter can be hesitant in lower gears; Track mode is overly aggressive for road use; the top end still feels a bit constrained.
Verdict
The 2026 KTM 790 Duke keeps the mischievous spirit that made the model popular while wrapping it in a more polished package. Handling remains its strongest suit, but suspension, brakes, ergonomics and electronics now make it easier to live with off the limit‑pushing rides.
In short, the Duke is still a playful, corner‑hungry middleweight—only now it arrives with a few more refinements that broaden its appeal without dulling its character.
