When it comes to reliability, KTM motorcycles, especially the Duke 790, have a bit of a mixed reputation. Riders who swear by their KTMs have had trouble-free riding, while others have had frequent issues and dealership visits. Much of the debate revolves around build quality, component longevity, and how often one requires repair versus the Japanese competitors. Individual experiences can vary due to factors such as maintenance habits, riding conditions, and manufacturing variations. We also discuss whether KTM’s performance-oriented design philosophy means more wear and tear or if reports of problems are all over the internet forums. Also in the reliability equation are the cost and availability of parts and service.
