I'm cruising along at about 70 behind a truck pulling a big camping trailer this evening, and the right rear tire comes apart, beating chunks of fiberglass & aluminum off of the side of the trailer and flinging it directly at me and my 919.
It seemed like everything was happening in slow motion, and I can remember dodging several large chunks of tire & trailer intentionally as I changed lanes and nailed the throttle, although it could have only been a couple of seconds before I was around him. I didn't get through completely unscathed, though, as I can remember watching one chunk bounce off the fairing and go over my head, followed by a chunk that caught my helmet in the middle of the forehead (snapped my head back pretty good, I'm sure pleased with my fairing and that helmet
) I also caught a small piece of tire in the left shin, which I'm pretty sure is going to leave a bruise. No damage to the bike.
So, when I got home, I picked up my 7 yr old son, we both geared up and rode out to bike night at Hooters to celebrate cinco de mayo for "guy's night out" (mom was at church game night.)
Point of the story: It doesn't matter how long you've been riding or how experienced your are, if a chunk of tire hits you in the forehead at 70 mph with no helmet on, it's definitely going to ruin your day, through no fault of your own. I'm sure glad I got to go to Hooters with m'boy.
