2014 KTM 690 Duke Full Review and Specs
This year KTM revived pure, pure single-cylinder motor with the engine in the form of the design Of the “original”. Judging from this latest 690 Duke design that stands before us today, many of the changes from the series before him, subtlety, space for a pillion passenger, long-distance capabilities. But what he never lost the intensive dinamikanya and riding. Most current series production single-cylinder engine of our time and precision chassis with a wealth of superb components changes every trip in the 690 Duke became an unparalleled experience and unforgettable horseback riding.
Design Single-cylinder, 4-stroke, spark-ignition engine, liquid-cooled
Displacement 690 cm³
Performance 50 kW (67 hp)
Weight without fuel approx. 149.5 kg
The finely balanced crank drive of the 690 single-cylinder converts terrific combustion pressure into unrivalled single-power – thanks to its balancer shaft, which eliminates vibration even better than ever without having any detrimental effect on the life of the super-single.
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 ride-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 slipper clutch that effectively prevents rear wheel chatter when down-shifting hard.
The disengageable 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.
INJECTION / ENGINE MANAGEMENT / RIDE-BY-WIRE
The electronic engine management system always gets optimum performance out of the ingenious LC4 engine. More advanced technology than ever is taken advantage of in 2012 for this purpose: Twin ignition with individual mapping for each spark plug ensures that the mixture is always burned effectively, irrespective of load and engine speed. And then genuine ride-by-wire, in other words electronically controlled throttle valve actuation without any mechanical linkage. So that the electronics always apply the power as perfectly and therefore smoothly as possible, above all on transition from throttle closed to throttle open. How good does that feel? Simply indescribable. So check it out!
INJECTION / ENGINE MANAGEMENT / RIDE-BY-WIRE
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.
CENTRALISATION OF MASSES
The Duke not only impresses with low weight and perfect chassis geometry; the centralisation of masses – for example, by positioning the brushed stainless steel pre-silencer under the engine – also contributes to its playful handling and razor-sharp precision.
FRAME AND SWINGARM
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.
Well-equipped for every situation: 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.
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.
NEW RIMS IN THE KTM DESIGN
New rims may not appear to be such an innovation at first sight nowadays. What new rims mean for a manufacturer perhaps becomes rather clearer measured against the present-day degree of perfection of practically all the parts of a motorbike: But major improvements don’t just take a couple of minutes these days. 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. Cool, don’t you think?
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.
GREATER RIDING PLEASURE YET EVEN MORE SAFETY – KTM 390 DUKE AND LC4 MODELS ABSOLUTELY A2-COMPLIANT!
Due to ambiguous or even incorrect press reports, confusion currently prevails in the KTM community throughout the EU regarding the A2-compliancy of the following models:
• 390 Duke
• 690 Duke
• 690 Duke R
• 690 SMC R
• 690 Enduro R
The corresponding press reports convey the impression that the mentioned models are too light and hence not approved for A2 beginners. This impression is inconsistent with the truth. The A2 driving licence prescribes a minimum power-to-weight ratio of 0.2 kW/kg, which is why KTM has homologated performance mappings for all the aforementioned models to make them A2-compliant. Thanks to the mappings, all the listed models achieve the minimum power-to-weight ratio precisely – quite the contrary to most of the overweight competition. Assisted by the mappings, every A2 beginner can benefit from the dynamic advantage of the models being so light – whether it be due to increased riding pleasure when accelerating, when riding demanding trails or due to the much more significant safety factor when braking, in general vehicle control or when evading sudden hazards. The models are therefore not only A2-compliant, but also highly recommendable for novice riders, since they guarantee greater riding pleasure yet even more safety.
