690 Duke 2018


Model Description

Two decades ago, the original Duke was nothing short of revolutionary. KTM's first single-cylinder street bike grew into a cult classic, adding extreme fun to a raw and radical concept. Today's 690 DUKE stays faithful to its ancestor's ways, but adds future-proof refinements: impressive smoothness, sophisticated electronics, improved ergonomics and tons of grunt. This firmly cements the world's strongest single-cylinder production motorcycle at the cutting edge of engineering. Long live the Duke!
The brilliant LC4 showcases twenty-four carats of fun. With its powerful, lightweight single combined with a sophisticated electronic engine management , dual-spark ignition with plug-selective mappings and a second balancer shaft, the results are top refinement, a wide powerband and a full 54 kW (73 hp) of peak power.
The 9 kg tubular trellis frame made from chrome-molybdenum steel and the equally lightweight, smoking hot swingarm, die-cast in aluminum, impress with extreme levels of torsional stiffness, providing the 148.5 kg Duke with excellent tracking stability and a continuous flow of information to the rider. Triple clamps lower the fork offset, which underlines this characteristic even further. You'll notice.
Despite its pronounced lust for cornering, the 690 Duke also presents versatile real-world capabilities. On a daily basis, particularly the two-piece seat will prove a valuable friend. It's comfortable and spacious, while still being set up for all dynamic riding situations. The seating position and freedom of movement behind the wide aluminum handlebar provide perfect support for controlling the bike both in traffic hell as well as cornering heaven. Workday commute or weekend blast: the 690 Duke has your back.
If the LED indicators, state-of-the-art finishing and DUKE genes didn't already convey the message, the intense orange rims together with the new color and graphics will make sure your ride stands out from the crowd. Which it deserves.
KTM know its customers like to modify and to travel, which is why the PowerParts range boasts a huge variety of accessories and luggage options across its Street range of sportmotorcycles – past and present. All PowerParts are developed alongside their chosen machine, meaning that KTM riders only get parts that perfectly complement their ride and provide that important 'factory fit' straight from the dealer.
