My wife will only ride the Rocket, because she has a backrest,my fault. We went for a ride on my Sprint once, getting on, she asked what the grab rails on the seat were for, I said just something to hang on to, without a thought. Now anyone in the world, rider or not, has seen a million times, even if just pictures, a girl on the back holding on to a guy. But my wife is very blonde, and very literal. On a straight, I said, hang on, and did a 60=120 or so, and back to 60 blast as we approached a bar we were going to for lunch. When we got off she looked really sick and shaken, I hadn't noticed she hadnt put her arms around me, she thought she was supposed to hang on to the rails on the side of the seat, she said the wind blast pushed her horizontal off the back of the bike, scaredest she'd ever been in her life, almost threw up in her helmet.Says she still gets sick to her stomach if she goes near that bike.
