Pros and Cons in comparison

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.
