You will gain stability that you done have on two wheels. You will undoubtedly loose a bunch of buttons and switches you never used on your Goldwing. As for handling in the corners, you will struggle at first, as it is a whole different way to ryde. Once you get a couple thousand miles under your belt you will be pleased as to how well it handles in turns. As for passing, the Spyder can pass anything on the road with ease! Plenty of power to handle what you need!
Never had a Goldwing. My Valkyrie was as close as I ever got to one. But if your experience is like mine. You will hate your new Spyder at first. Your 2 wheeled brain will think you are on a motorcycle and it won't like what it does. It will feel twitchy and somewhat uncontrollable to you at first. But knowing that it is you and not the machine really helps a lot.
The 'Do's and Don't's' list people mention will help you over the learning curve more quickly. And this is the key. Some give up right away and never experience the great ride the Spyder provides.
Once you get the hang of it you will be really glad you did. It's a great experience and worth the effort.
Hopefully, you won't struggle like I did. Not everyone does. But if you do. Just take your time and you can always come back here for some specific answers if needed.
Good Luck! :thumbup:
