The 2013 KTM 690 Duke is powered by most cutting-edge series production single-cylinder of our times – a single-cylinder, 4-stroke, spark-ignition liquid-cooled engine that cranks out 67 hp. The engine features plug-selective mapping for the best and most effective combustion, plus extended service intervals of 10,000 km.
As far as ergonomics go, the new 690 Duke comes with a comfortable two piece seat which offers freedom of movement and an ideally angled aluminium handlebar which helps you maneuver the bike with agility. For a sharp stopping power the motorcycle is equipped with a disconnectable dual-circuit ABS system with 9M+ modulator tuned in cooperation with Bosch.
Back then, KTM revived the pure, unadulterated single-cylinder motorcycle in the form of the "original" Duke. Judging by the latest 690 Duke that stands before us today, much has been gained: smoothness, room for a pillion passenger, long-distance ability. But what it has never lost is its intensive and elemental ride dynamics. The most cutting-edge series production single-cylinder of our times and a precision chassis with a wealth of outstanding components turn every trip on the 690 Duke into an incomparable and unforgettable riding experience.
Lightweight components in a large, lightweight entirety: The 9 kg lightweight tubular space frame made from chrome-molybdenum steel and the 4 kg lightweight, high-quality, pin-jointed, die-cast swingarm impress with extreme levels of torsional stiffness, providing the less than 150 kg 690 Duke with excellent tracking stability.
The WP upside-down fork on the Duke with a 43 mm upright tube diameter and the pivot-arm articulated WP pressurised-gas monoshock excel with perfect tuning and an unbelievably broad spectrum of use for all demands, from relaxed cruising to racing around closed circuits.
KTM has nevertheless allowed the best technicians to play around with very clever computation software until an extremely lightweight, aesthetically elegant but still very stable and durable set of rims emerged from the casting die. Slightly lighter, but far less rotationally inert because the weight was saved predominantly at the rim ring. The result? Faster acceleration, shorter braking distance, quicker changes of direction – simply a faster motorbike.
The Duke’s extremely powerful and easily applied Brembo® brakes impress with outstanding controllability. At the front wheel, a radially-mounted, four-piston, fixed brake calliper bites onto a floating, 320 mm brake disc.
The disconnectable dual-circuit ABS system with 9M+ modulator tuned in cooperation with Bosch offers total protection against over-braking, while maintaining the full effect and perfect feedback of a genuine sports brake thanks to very fine sensors. Weighing no more than one kilogramme, the ABS system therefore allows extremely sporty braking. And prevents nose-overs actively and effectively.
The new 690 Duke inherits many of the benefits of its predecessor: for example, the low weight of less than 150 kg, the first-class handling and the outstanding brakes. Particularly pleasant is the place of work on the two-piece seat: Comfortable while still being set up for all dynamic riding situations, because the gathered sitting position and freedom of movement behind the ideally angled, wide aluminium handlebar provide perfect support for controlling the bike.
Thanks to the mechanical and electrical refinements, the new 690 Duke uses even less fuel than ever. Even though the last Duke had already won international consumption comparison test rides with ease. Duke riding will therefore be even more economical and environmentally friendly, while remaining unashamedly fleet-footed, sporty and dynamic.
The new Duke is equipped with the latest version of the legendary LC4: A whole 690 cm³ of displacement, twin ignition featuring plug-selective mapping for the best and most effective combustion, plus extended service intervals of 10,000 km and even lower fuel consumption – never has it been as elegant, cultivated, sporty and effective to be powered by one cylinder.
And never has the need for more cylinders been more questionable. 50 kW (68 PS) provide, thanks also to drive-by-wire, extremely powerful and free-revving thrust at all engine speeds, hence making light work of the equally lightweight 690 Duke. It has adopted such well-known standard production goodies such as active engine casing ventilation and the anti-hopping clutch that effectively prevents rear wheel chatter when down-shifting hard.
