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.

Yamaha MT-03 2019

The MT-03 remains Yamaha's most accessible and pragmatic Hyper Naked in the segment. It scores with its low seat height, the easily controllable power of the two-cylinder and at the same time offers enough comfort for commuters. What it may lack in sportiness, it makes up for in comfort, making it perfect for people looking for a well-functioning motorbike with a brutal look. However, you shouldn't be too big, and you shouldn't aspire to keep up with the other models in the MT range at the angle - because that's not what it was designed for. The 2020 model year is thus a coherent update that is sure to make its buyers happy.
