All good advice so far, my wife has been my passenger for over a hundred thousand miles,
quite a accomplishment considering she had never been on a motorcycle before she met me.
One of the best things I ever added to my bike was the intercom system,
it made our time on the bike together more intimate and enjoyable,
it also provided her with opportunities to tell me how not to drive to fast,
where she wants to shop, eat or stop for bathroom breaks
It's all worth it to have her with me.
When we depart, I get seated on the bike with both of my hands on the handlebars,
I give her the go ahead, she climbs on, grabs the handles on both sides and we ride away,
same thing dismounting, I will usually deploy the centerstand while we are both still seated,
then I give her the go ahead, she dismounts first, then I do.
The only thing I would like to add to that is stop often and make sure it is nothing but enjoyable for her.
I'll give you an example,
when I was single I would do as many BMW rallies as my schedule allowed,
When we were dating, I took my wife to the north Georgia rally,
(her first camping and rally experience)
it rained for three days, we left early and went to a motel,
it took almost two days to get all our gear dried out,
because of that she doesn't camp or go to motorcycle rallies,
if I want to go I go alone.
