If you are struggling to hold her up it's time to think hard about letting her go. What scares me about this is not the bike falling but the possibilities that stem from mature hips, knees, ankles, shoulders being put under too much stress if she goes over in a carpark that might put an end to the fun for quite some time. After the ST I'm, not sure that a smaller tourer would do the trick 2 up. I've ridden the CFMoto a bit and while it'd be great as a cheap 1 person tourer it'd struggle with 2 on it. The 800 beemer, maybe. The spyder, great idea if you enjoy it on the test ride.
