After the very special 690 Supermoto, and its duck nose very « original », KTM continues the renewal of its monocylinder range.
Its on the 690 Supermoto base that engineers started to work, as the result of a duke festured with the beautiful looking treillis frame.
Its also powered by the same engine of its sister, the 654cc monocylinder four valves who delivers 65 Hp at 75°00 Rpm and 67 Nm of Toorque at 5500 Rpm.
The others evolutions of the austrian beast are that its now featured with a whole new exhaust system. Exit the two silencers under the seat, welcome a bige silencer under the engine, Buell Styled.
The seat is also new, now low-cut, this new seat will not any more allow the rider to move on the bike, but will certainly be more comfortable for the back and the bottom...
For the suspensions and brakes, KTM decided to keep the same suspensions as the Supermoto, WP 43mm upside down front fork and rear damper WP. The new Duke is featured with a four pot Brembo front caliper radial mounted on a 320mm disc.
At last, talk about the look, the new Duke is always as it was, and even closer to the KTM style, sharpen lines, angular, it os now featured with a small engine boot.
