KTM 390 Duke 2021

KTM 390 Duke 2021

The KTM 390 Duke is a "real" Duke. The trademark: Extremely agile handling that makes for powerful riding fun. The flyweight 390 can be precisely controlled with its narrow waist and wide handlebars and feels most at home in tight corners. Especially with the Supermoto mode, it is a fun machine without equal. Unfortunately, only the brakes and suspension of the 390 cannot maintain the same, very high performance level as on the 125 Duke or 890 Duke. They feel a bit spongy and not optimally tuned, especially when the rider weighs in a bit more. The equipment is otherwise tip-top, especially when you consider the price of the 390 Duke. In terms of riding pleasure/euros, it outperforms most, including its Duke sisters.

Typical Duke ergonomics that are also suitable for taller riders

Sporty engine with great handling

Modern TFT display with smartphone connectivity

Supermoto mode is a pleasure

In a direct comparison, the KTM 990 Duke is the more sensible choice, without feeling sensible or even boring. Its 123 Horsepower twin-cylinder engine delivers the same powerful grunt from low revs as the R, runs smoothly and is hardly any less fun on country roads. The softer WP suspension also offers sufficient support for a very sporty pace, whilst remaining slightly more accessible in everyday use and on longer journeys. For most riders, the standard Duke is perfectly adequate. It’s only during very hard braking manoeuvres, at high cornering speeds or with regular track use that it reaches its limits sooner than the R. Those who can do without the more modern touchscreen get a powerful, versatile naked bike with surprisingly good long-distance capabilities.
