The KTM Duke 790 is loved for its performance and handling, but some owners have had problems with their bike. The problems can be anything from a minor annoyance to a serious mechanical failure. Knowing what common problems are can help potential buyers make an informed decision, and owners already owning a 7 Series can prepare themselves for any future issues. It’s also interesting to see how these issues compare to other bikes in the class and whether they are deal breakers or just part of the ownership experience. Others say the 790's problems are blown out of proportion, while still others argue they're just symptomatic of KTM's overall build quality and reliability.
