Ktm Duke 690
The Ktm Duke 690 has a top speed of 175 km/h, produces 73 hp and weighs 149 kg. Motoryk rates it 7.8/10.
La KTM 690 Duke a été introduite en 2008 en tant que successeur de la 640 Duke, équipée d'un tout nouveau moteur monocylindre LC4 et s'est imposée comme la moto monocylindre de série la plus puissante au monde à l'époque. Il a fait l'objet d'une importante refonte de deuxième génération en 2012 avec une ergonomie et une électronique améliorées, suivie d'une autre mise à jour majeure en 2016 introduisant le roulage par câble, l'ABS dans les virages et l'antipatinage. Il demeure un modèle de streetfighter monocylindre de référence, célèbre pour sa légèreté, son agilité, sa puissance et sa maniabilité inspirée des supermotos.

Ce que les acheteurs doivent savoir
Single-Cylinder Powerhouse
The 690 Duke's LC4 engine is one of the most powerful production single-cylinder motors ever made, producing ~73hp. This unique character gives it aggressive performance rarely found in its class.
Watch the Valves
The LC4 engine requires strict valve clearance checks every 6,000 miles — skipping this is the most common cause of costly engine damage on used examples. Always verify service history before buying.
Strong Resale Value
KTM 690 Dukes hold their value well due to their niche appeal and loyal following, often retaining 70-80% of value after two years. Low production numbers and high demand keep the used market competitive.

Présentation d'un monocylindre LC4 de 654 cm3, d'un cadre en treillis et d'un design de streetfighter nu inspiré du supermoto.
"Une arme urbaine brute et percutante dotée de véritables manières autoroutières."
Le 690 Duke Gen 1 semblait vraiment dérangé de la meilleure façon possible : ce moteur de 654 cm3 à combustion unique est doté d'un aboiement mécanique qui donne aux jumeaux parallèles une sensation de stérilité en comparaison. Le couple atteint ses limites aux alentours de 3 500 tr/min et ne cesse d'augmenter, ce qui signifie que le filtrage de la circulation urbaine est facile et légèrement dangereux. Le cadre en treillis et la géométrie de la supermoto le rendent vraiment clignotant, presque télépathique dans les virages serrés, bien que les vibrations du monocylindre au-dessus de 6 000 tr/min vous engourdissent les mains pendant plus de 90 minutes d'autoroute. Les premiers exemples présentaient des problèmes de fiabilité : les pannes de stator et les problèmes de consommation d'huile étaient des problèmes réels et documentés, et non de la paranoïa des forums.

Évaluation d'un acheteur d'occasion
"Raw, rewarding, and punishing if you buy blind."
$4,500-$7,500 usedThe 690 Duke is one of those bikes that rewards riders who actually want to ride, not just commute. That LC4 single thumps with genuine personality — torquey from idle, surprisingly capable on a back road, and light enough to thread traffic without breaking a sweat. KTM built something genuinely exciting here, and used prices reflect that reputation. Here's the honest part nobody tells you: budget for maintenance before you budget for the bike. The LC4 engine needs valve checks every 15,000km, and previous owners frequently skipped them. Pull the service history or walk away. Pre-2016 bikes also had some throttle body issues and frame cracking reports worth investigating. The 2016 refresh sorted most gremlins, so target those if possible. Ride one back-to-back against a parallel twin and it'll feel raw, even rough. That's not a flaw — that's the entire point. If you want smooth, buy Japanese. If you want engaged, buy this.
