Okay, here's the deal. I have been riding, off and on, for forty+ years. Started on two Hondas and then switched to two Harley shoveheads. A 1973 FLH and a 1977 Superglide FXE. The FXE is my current bike. I love this bike but my wife hates it. The ride for her is horrible, to hear her tell it. Admittedly, the constant maintenance is finally starting to wear thin on me, also. But it is a forty year old bike and it kinda goes with the territory.
I will be selling it and moving in the Honda direction for what will be my last bike(s). I am not concerned about me and my comfort as much as I am my wife's. She has Parkinson's and needs a comfortable seat, boards and windbreak. I know I should be looking at a Goldwing but I really don't want to go there if I can make a '14 Valkyrie work comfort wise. If I could strip the bags off the GW and if it would still look like a motorcycle I would probably go for it. The 1500 Valkyries look better than a GW in my opinion and I might go in that direction. A 1500 GW and a 1500 Valkyrie could probably be had for the same money as a 2014 (I love the looks of this bike) Valkyrie. Old bikes don't bother me as long as they are dependable.
Long winded, I know. End result is a bike that will relatively wrench free and comfortable enough to keep my wife on the seat behind me. Which she really wants to do but not on a shovel. People are so spoiled nowadays.
I live in Tucson.
First off. You got a 77 Harley ? My hats off to you. That's no small feat in itself.

I think either the Valkyrie or the GW is going to seem like heaven to your wife. I only know 2 new Valkyries in the state. But I don't think either carries passengers. Do you ride that Harley as far as Prescott ? If so, you should ride up to the gathering next month. They might be there. I've decided at my age, I'm figuring in the price of a Russell seat in the purchase price. Will never go back now.

Good luck in your search. Get the Valkyrie, a seat, back rests, arm rests for your wife. Take them off when solo.
