I've gone back and forth between ST1300's and Goldwings. I think I've had three ST1300's and two Goldwings. If I could get either one, brand new, for the same price, it would be a tough decision. The ST1300 is sportier (obviously) but the Goldwing is more comfortable. I'm 57. The older I get the more I like the Goldwing. Plus in Florida there are many more used Goldwings available than ST1300's. So I'm back on a Goldwing right now. I'd cross the country with either one. And both work great alone or two up. You can tow a trailer with either one too. And they are both dead reliable. I wish they sold a less expensive version of the Wing that didn't have so many bells and whistles on it. That would be the bike for me!
Have you looked at the CTX 1300? Same drivetrain as the ST. I have one for sale in Las Vegas.
I went with an ST 1300 about four years ago because I wanted something that weighed less than my wing. now everyone is telling me to get a new wing but that would mean a heavier bike and smaller gas tank, two things I don't want
