Welcome to the GWO forums, calmonk1!
The 'Wing can be a little tougher at slower speeds, for sure, but....practice makes it better. 2-up riding requires cooperation, too. I always tell Mama "No sudden moves, if I lean you lean, and don't slap me like you do in the car..." LOL!
I rode a "nekkid" "wing back when they first came out in '75. It was simply too big a bike for me then, so I went to a smaller 750. I only weighed about 145lbs at the time. I've put on a few pounds since then, and now the Goldwing isn't such a handful for me. I bought the '81 IS last June, and I've gotten fairly comfortable on it since then, so parking lots, or Mama on the back don't pose as much of a problem as they did then.
Keep on riding, and have fun!
