Description

Two decades ago, the original Duke was nothing short of revolutionary. The first single-cylinder urban KTM motorcycle became a cult classic, adding extreme fun to a wild and radical concept. Today the 690 DUKE remains true to the character of its ancestor, but adding some futuristic improvements: impressive smoothness, advanced electronics, improved ergonomics and tons of punch. This secures the already strong foundation of the world’s strongest single-cylinder series production motorcycle, at the forefront of engineering. Long live the Duke!

The brilliant LC4 engine exhibits twenty-four carats of fun. With its powerful and lightweight single-cylinder engine combined with a sophisticated electronic engine management system, double-spark ignition with selectable maps and a second balance shaft, the results are maximum refined feel, a wide power band and maximum power output. 54 kW (73 hp).

Both the lightweight 9kg multi-tubular chrome-molybdenum steel chassis and the equally lightweight die-cast aluminum swingarm impress with their extreme levels of torsional stiffness, giving the Duke of 148.5kg a excellent directional stability as well as a continuous flow of information to the pilot. And you will notice. You will notice.

Despite its unbridled passion for cornering, the 690 DUKE is also highly versatile in the real world. In daily use, the two-seater seat will be a valuable ally. It is comfortable and spacious, and at the same time designed for any dynamic riding situation. The position in the seat and the freedom of movement behind the wide aluminum handlebars are the perfect support for the control of the motorcycle both in the hell of urban traffic jams and in the sky of the attack to the curves. On the daily commute or on the weekend getaways: the 690 DUKE will always be by your side.

If the LED lights, the exceptional finishes and the DUKE genetics are not yet enough to transmit the message, the intense orange of its rims together with the new color and decoration will do the rest so that your motorcycle stands out from the rest. Because it deserves it.

The great variety of high technology that it incorporates reflects the high quality standards of the KTM 690 Duke.
