i've crashed a good 20+ times over the past 5 years... haha (most in my first year of racing)
most at a fairly low speed on 100cc bikes though. only 2 that i can think of that were above 50mph, but that one gave me a slight concussion. only injuries i've had is a broken collar bone, a half dozen cracked ribs and a cracked tailbone. not a bad average really. main reason for all the cracked ribs is that i have
11 vertebrae fused (scoliosis). my body doesn't bend and flex when i hit the ground like its suppose to.
