Looks to retro for my taste, a nice hi-back would offer up the nastalgic appearance and age or vintage look. My Chief is solo, so for now and maybe for ever I’ll just use a couple of interchangeable back rests I’ve made. If your mate or whoever rides with you fell asleep I’d be worried. I use to use a harness for my daughter, a belt goes around both of us and keeps us tighter together. She’d be wide awake on our take offs and the ride, when I said time for home, her lights would go out.
