Ever fall doing 50+. We had a blow out (new tire/tube, no brakes) at that speed on the rear around a bend in the road. The rear decided to try and change places with the front so, I laid the bike down instead of highsiding. The noise was incredible. I didn't get out of the drops the entire 175'. The grinding on the ground was so severe it completely ground down a ti speedplay to the mid way point on the spindle. My wife broke a shoulder and was banged up a bit. My hand now only has an index finger and a thumb with any knuckles. 300 stitches and it was ugly. We now decend at 40mph max. My stoker's to important to take any more chances. We have got away with some crazy things riding the tandem. Some get off lucky. I feel we did. Took a year to get back on.
