Everything will need maintenance and repairs. Doesn’t matter if it’s a motorcycle, a car or truck, a boat, a house, or whatever. While some things are easier or cost a little less for upkeep I generally wouldn’t factor that into my decision too much.

Oh, and just to muddy the waters and perhaps ruffle a few feathers, the reason I have never owned a dual sport is simple. It’s too much of a road bike to really be good off road and it’s too much of a dirt bike to be really good on the road.
