KTM 790 Duke 2018

The KTM 790 Duke L is an absolutely sporty naked bike with a high fun factor. Whether a beginner rider can handle it depends very much on his or her personality and riding behaviour. There are certainly motorbikes better suited for learning, but sporty radius hunters will hardly be satisfied with anything else. The 790 Duke L is also rather unenthusiastic about everyday rides in the city. On the country road, however, it's a blast, even with only 48 hp. Simply a fun bike as it is written in the book.

The ingredients for the 2021 update are right: More power, more equipment, more electronics, less weight. If you take a look at the key data of the latest MT-09, including its over-complete standard equipment, "mid-range naked bike" almost sounds a bit pejorative. The Japanese engineers have made improvements exactly where they were needed. The swaying chassis is now a thing of the past and the load change reactions have also been eliminated from the revised three-cylinder engine. The additional power paired with a little more pressure in the mid-range gives a sovereign riding feeling. The MT-09 offers a lot of equipment and enormous riding pleasure at a very attractive price. If you like the look, you can buy it without hesitation.
