Ok I tried the search but couldn't find anything on this. I've got comfortable riding solo, but I know my wife is going to want to come along. What should I expect or have to change when I'm riding with her?
Exactly what I was going to say. And don't let her gt in the habit of trying to "help" you because it's hard to break. The first time she does it, stop and talk to her about it. (In a friendly way if you want dinner that evening!) And be aware she might not just lean into the turn further than you would expect, she may also lean OUT of the turn, which will cause you to have to lean the bike more, possibly digging in a footpeg or bar and lifting the tires off the ground.The quickest thing she needs to learn/understand is to not do any leaning. that may come later with experience but an unexpected extra lean from a passenger can put you right down.
The most she should do is move her head so that she can look over your inside shoulder. Other than that she should let you do everything and she should just relax and not try to help.
I know several couples who tour all over the country and their wives sit back there and read a book or go to sleep. They have been at it for years and have the experience. That takes time.
