Short ride, she is very nervous about falling off and can't relax and enjoy the ride. Shock bottomed out once.
On a positive note, we went and test-sat a can am spyder rt, and she liked the more secure feel of that.
When my wife rode with me, I was trying to decide 'Do I get a Wing for that?' or 'Do I spend a little money on my ST1100?'.
I decided to spend the money on a Russell Seat (got the back seat fixed for her, the front for me), new heavy duty rear shock and redid the front end.
Plus I added a trunk with a nice backrest and moved it back a little bit so she would have more room.
She did a test ride on the back of an 1800 Wing said the ST1100 was much more comfortable for her.
Unfortunately now she can't ride due to health issues so in hindsight I am glad I didn't get a Wing.
But you have to do what works for the both of you.
Just a note - the rear shock on ST1100s tends to turn into a pogo stick around 50,000 miles or so.

I used to run Works Pro Racers on the rear til the original owner died.
I tried to have one rebuilt under the 'new' management and it was quite painful and did not work very well.
Now I've swapped to Wilbers like ST1100Y and I am super pleased with them.
And I had GMD Computrack Atlanta rebuild the front ends with the RaceTech springs and gold valves - what a difference!
