A good seta and a sissy/pillion backrest will make a world of difference in their comfort to be on the back. I had a pillion sleep on the back once on a long haul trip...wondered why her helmet kept tapping be in the back of the head. lol
Tell them to punch you in the kidneys if they get scared, and not to bother yelling at you. That way you'll learn pretty quick. Make sure you have a pillion seat and footpegs on the bike. Sissy bar or pillion backrest is a very good idea if you want them to come back for a second ride.
LOL....you lunatic Steve
Well I try! But seriously, it's no good a pillion yelling at you, you're not gonna hear, so the punch in the kidneys is an effective way of them expressing their concern. And make sure you have a seat and footpegs? I've seen a woman sit on a cushion bungied to the back of WLA from Maleny to Maidenwell. Not only no seat or footpegs, no suspension either.
Ha Ha you did mention "bacon" that could be offensive to some...
