Ktm Duke 790

The Ktm Duke 790 has a top speed of 220 km/h (estimated; KTM does not officially publish a top speed figure), produces 95 hp and weighs 169 kg. Motoryk rates it 8.5/10.

La KTM 790 Duke a été présentée à l'EICMA 2017 et a été mise en vente en 2018, ce qui lui a valu le surnom de « The Scalpel » pour sa maniabilité exceptionnelle et ses performances agiles chez les poids moyens. Elle s'est notamment distinguée par l'introduction de la toute nouvelle plate-forme de moteurs LC8c à deux cylindres parallèles de KTM, comblant ainsi l'écart entre la 390 Duke et la 1290 Super Duke, plus grande. Le modèle a finalement été remplacé par le 890 Duke en 2021, qui utilisait une version alésée du même moteur avec une puissance de sortie améliorée.

Ce que les acheteurs doivent savoir

⚙️

Parallel Twin Sweet Spot

The 799cc parallel-twin engine delivers a strong 105hp with a broad powerband, making it unusually versatile for both city riding and track days. It's widely praised as one of the best middleweight engines ever built.

⚠️

Watch for Stator Issues

Early 2018-2019 models had known stator and charging system failures that could leave you stranded. Always check service history and ask if the stator has been replaced or updated before buying used.

📉

Decent Resale Retention

The 790 Duke holds its value reasonably well due to its cult following and the fact KTM discontinued it in favor of the 890 Duke. A clean, low-mileage example commands a premium on the used market.

Experienced riders wanting thrilling, affordable naked performance

"Buy one with full history and never look back."

$6,500-$9,500 used

The 790 Duke is genuinely one of the best middleweight nakeds ever built, and buying one used is arguably smarter than new. KTM sorted most of the early software gremlins through updates, so find a bike that's had those done and you're inheriting a properly sorted machine. The LC8c parallel-twin pulls hard from 3,000rpm and absolutely screams past 8,000 — it feels more alive than the numbers suggest. Ergonomics are aggressive but not punishing for experienced riders. Be honest with yourself about KTM's reliability reputation though. These bikes need their service intervals respected. Check the throttle bodies are balanced, verify the WP suspension hasn't been neglected, and look for signs of track use — plenty of these got hooned hard. The TFT dash and cornering ABS are genuinely brilliant tech for the money. Budget for consumables; Supercorsa front tires don't last forever.
