When my wife got on my Sprint, she asked me what the grab rails were for, I said just something hang on to. Now I would assume anyone at all, even if they never rode before, would know a female passenger puts her arms around the rider to hold on. I told her hold on, and took a quick blast to 120 and back down before pulling in to get gas. She said the wind blast almost took her off the bike, she was holding on to the grab rails but the wind had her laid out straight on her back, she said she almost threw up in her helmet, she was so scared . She never got on that bike again, she said just seeing the bike makes her sick to her stomach. My fault, I just assumed anyone would know that.
