Awesome bike, but it’s massively heavy and not at all conducive to learning. It’s really a purpose-built bike, and that purpose is touring. If I was retired and planning to take some multi-week trips or weeklong trips with a passenger, the Goldwing would be on my short list. But if my goal was a 15 mile commute and a weekend trip here or there, it’s overkill and cumbersome (IMO).
I ride a Concours (1000cc sport tourer). It’s significantly smaller than the Goldwing, but still feels like overkill on my daily commute (90+ miles RT).
Assuming you like the standard ergo (Goldwing), I’d suggest looking at the Suzuki 500, maybe the SV650 or WeeStrom, the Ninja 500, maybe the Ninja 650 or sisterbike Versys. Many of these are typically better as 2nd bikes, but they are also considered to be manageable to more mature riders with off-road experience. All will also offer comfort for commutes and weekend rides, as well as the ability to carry the occasional passenger (although you really should put that out of your mind until you have many months of riding under your butt).
And FYI: height is no advantage on a Goldwing. The seat height is no challenge for most. Folks are not typically dropping their bikes because they are too short or too weak, it’s because they don’t know what the hell they are doing and/or are way over their heads in terms of ability.
