Hay Kami,
part of the training I gave my kids when I tot them to ride street bikes was me, with ALL my gear on, and them riding me around town. After a few times, and them getting some confedence, I would tell them "Im going to shift my wate." Giving them a heads up of me being a bad passenger. Wow that helped them be better riders. Now, they can tell there passenger if they are doing somthing wrong to stop it.
Get one of you buds to do that for you. The more leather they have one, the less you will be afraid they will get hurt in a tip over.
Just a thought?
