KTM, the Austrian bike manufacturer best known for its fabulous off-road title winning machines, has sets its sights on becoming Europe’s largest motorcycle manufacturer. But, to do so it needs a comprehensive range of machines to compliment its excellent off-road competition machines.
Recent successes on the racetrack show that they now have the technology to move forward and diversify onto the tarmac. Obviously any advances in competition will reflect in its road-based models, meaning they will be—and if the Super Duke is anything to go by,they are—state-of-the-art and able to compete with other larger more established manufacturers.
The Super Duke arrives in Europe just a year after KTM launched its first twin-cylinder motorcycle in the shape of the 950 Adventure. But while based on it, the Super Duke itself is virtually all-new.
KTM has upped the capacity of the Adventure’s 942cc LC8 engine to form the heart of the 990 Super Duke. As you would expect, there is marked performance gain that comes from more than just an increase in cubic capacity to 999cc. New fuel injection and engine management systems are just part of it.
The narrow-angle V-Twin is one of the lightest and most compact twin-cylinder motors on the market, weighing in at 58kg (128 lbs), roughly one-third of the bike’s overall 179kg (395-lb) dry weight. KTM says a further 15kg (33 lbs) can be dropped by making use of the carbon fibre performance parts already on the parts shelves at the factory. Needless to say, these are not cheap!
The cylinders have been strengthened to deal with the larger bores, which have very light pistons running inside them to help reduce the oscillating mass. The head has been worked on to deal with the new 48mm injector bodies (the Adventure uses carbs), new camshafts and the thicker header pipe. At the bottom end, the crankshaft has been changed and a new six-speed transmission has been developed specifically for the street.The Keihin electronic injection system was tailor-made especially for the Super Duke. There are two throttle valves per cylinder feeding the flow-maximized intake ports. These ensure the perfect mixture preparation and optimum torque progression in every riding situation. Lamba sensors, a catalytic converter and secondary air systems ensure that the bike meets all emissions standards across the world with ease. Claimed output is 120 horsepower at 9000 rpm with the maximum torque of 74 lb-ft coming at 7000 rpm.This Bike is all muscle and Grunt!

To further emphasize the idea that the lines of its motorcycles are directly related to the curves of the human form, Ducati has hired photographer Elizabeth Raab to show the relationship in naked light, so to speak. This set of photos really succeeds at setting off the talents of Ducati's designers at nailing the human form in cold steel.
To achieve the brief, Raab threw some nude models atop Ducati's most-desirable models and added delicate lighting, to show off the lines of both subjects just so. The result, as you can probably imagine, will leave both gearheads and non-gearheads thoroughly agog. Think of it as a slightly less-NSFW version of the Pirelli calendar.
While we're sure this calendar has some serious artistic value, and we the photography is undoubtedly brilliant, at the end of the day, it's nude models on top of Ducatis. We can't think of a more thrilling blend of two things we are definitely for. If you want your own copy of the Elizabeth Raab calendar, head over to Ducati's website ASAP, they're selling limited numbers of these things, and we'll bet they're going to move fast.
That’s what modern high-performance sport is like on this purebred enduro: you sit on it and feel that everything is just right – the seating position, handlebars, footrests, it’s simply perfect. Then you look ahead: there’s never been a bike with a more streamlined steering head. What geometry! Almost straight frame tubes – made of the finest steel – right down to the swing arm bearing. And there’s the next highlight: the swing arm and pinion on one shaft – or coaxial as the experts would say. The effect is a tight chain in every situation on the road, whether the suspension is on full rebound or compression. And that means traction at all times! And then you understand the principle of this unique construction: the distance saved between the pinion and the swing arm bearing fully benefits the swing arm length, which means even more traction! Greater length at the rear allows for a steeper fork at the front – making the machine agile but with excellent directional stability! Then there’s the engine: fuel injection, an almost straight intake tract, maximum efficiency with the most compact layout. BMW intelligence is seen here once again: the clutch on the crankshaft, making the engine extremely short in length!We could go on like this for pages – low centre of gravity due to fuel tank under seat, coloured mounted parts, fine quality components, compliance with EU-3 and street-legal. But why bother – when you can just sit on it, and all you will want to do is ride. And you’ll see why our engineers went to so much trouble. Get hold of your start number, because that’s what this bike is built for. Simply unstoppable!
