An incredibly well-designed motorbike. A lot of test work and attention to detail went into it. It has exactly the right power, exactly the right chassis and exactly the right look. An all-round successful naked bike that will make you happy for a long time. If you like, you can ride it simply and faithfully, but if you want, you can also ride it really fast and it wheels like hell. Great!

KTM 890 Duke 2021

KTM 890 Duke 2021

The predecessor 790 Duke already proved that KTM knows how to build a mid-range naked bike for the road. The new 890 carries the torch with a puffy chest and once again lives up to its scalpel nickname. Lively, it pulls the radii and gives off a certain nervousness that can be interpreted as a wild character. The equipment is almost complete - but only almost. Why do you have to pay extra for the quickshifter when it was standard on the predecessor? It is all the more annoying that the clutchless upshifting and downshifting functions as smoothly as butter and that one would not want to do without it.

does not arouse a desire for the R version on the country road.
