My wife and I ride all the time together and it's gotten to the point that I can't tell when she's back there. She'll give me the nudge when she gets antsy about the speed usually around 150-160. Cruising around though she doesn't mind 80-100 and actually complains when we do the speed limit. There's not too many like her out there though. Soon though she'll be riding her own bike. Just have to get her through a MSF course.
