You may have been looking at the wrong thing. A 2017 is a GL-1800. Different bike but a 2017 is similar to mine with a car type alternator. You buy the entire alternator.
Yeah, It looks more like a field coil but I guess it is just a stationary stator. (Inside the alternator). Honda calls the part stator in the parts diagram for the 2017 that I looked at. The 1999 has something similar.
My parts supplier shows the 1999 alternator as being available form Honda. Sometimes their availability information is slow to catch up though. Is that the case here?
You can buy internal parts for them. (If not discontinued).
