Your evaluation on the subject is just about the same experience that I have had.
I have owned 3 new Harley's in the past. Each one developed it's own set troubling maintenance issues.
The Wing is rock solid. Oil changes are easy. The only downside involves the removal and reinstallation of the "tupperware" for any other maintenance beyond oil changes such as steering head bearings adjustment or replacement, air filter replacement, cruise control adjustments and such. The removal/replacement process of the "tupperware" has a learning curve that requires some patience.
