I guess it depends on your definition of crash!
I have dropped my bike off road a dozen times, got rear ended at a stop sign in 1984, and dropped my R1100GS turning right when a guy illegally u-turned in front of me. How many crashes is that?
On the other hand, my brother was learning to ride and dropped his bike in the parking lot half a dozen times. One weekend, when he had 3000 miles experience, he crashed three times, twice over cooking a corner, and the last a high side from not seeing me stopping in front of him and locking up the rear brake. He totaled it that time and hung up his helmet for good. Proof some should not ride.
