Hey, GfS - My friend Raptor embedded his Harley in the wall of a local ice cream store last summer. The bike did not survive. He did....just barely. It probably happened because he hit a bump, got off balance, and unintentionally accelerated the bike and lost control of it. (this has happened to more than a few people) His recovery has been gradual, but steady, and his Harley-riding days are over.
