Is KTM hard to maintain?

Could you elaborate on the maintenance challenges associated with KTM? I've heard varying opinions on its upkeep and I'm curious to know if there are any specific issues that users frequently encounter. Are there common problems with its software updates, network stability, or any other key components? How does the community typically address these issues and what measures can be taken to minimize potential downtime or inefficiencies? Your insights would be greatly appreciated as I'm considering KTM for my next project.
