Well, I finally took my significant other for a ride on my Ninja ZX 6R twice this past weekend (fantastic weather). Just a simple spin out to UBC and around Stanley Park. It was my first time 2-up and I didn't want to do anything too crazy.
It was great, she really liked it. But she complained of wrist fatigue. I told her to put one arm on the tank and the other arm around me, but she found that both hands on the tank was better (and worked out well for me since she didn't keep sliding into me when I stopped).
But she said everytime I slowed down or stopped (and I stopped slowly, no sudden stops), she would have to push against the tank with her arms/wrist. And her wrists felt sore and tired shortly after.
Is this normal? Any advice on how to avoid this?
Thanks for the previous tips on 2-up riding for novices, it was very helpful.
