Back Rest for CB1100

[Bighonda14_imp]

I hope to locate a CB1100 this summer, and once familiar with the bike invite my almost 10-year old daughter to join me on some rides. For other parents who are members here a few questions:

Any suggestions on the best back rest to attach to this bike? Would like something that gives her a bit more confidence that she won't slide off.

Does 10 years old sound like a reasonable age for a first experience on the back of a motorcycle?

Any other suggestions/comments related to riding with a child on the back?

Thanks!
