Pros and Cons in comparison

KTM 690 Duke 2018

KTM 690 Duke 2018

Considering where the KTM Duke family once started, the 690 Duke is an incredible step forward. The engine is extremely refined and at the same time husky for a street-legal single-cylinder. Despite all the technology on board, it is still a very light motorbike and can almost be called a toy (in a good sense). Only its seating position divides opinions, because with the Duke 4 in 2012, the former supermotos became an almost tame naked bike with a front-wheel-oriented seating position. The advantage: everyday life and long tours should not be a problem on the current Duke.

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.
