In 2010 (last year available) AMA received 44 reports of incidents (37 property damage + 7 personal injury) and had 27 liability claims field (23 property damage + 4 personal injury). Over that time frame I do not recall hearing or reading about any incidents associated with a loss of control at an event or otherwise. Not saying it did not happen, but I do not recall any being reported on the forums. I am betting that if there were any they would have made the news as it were.

Not having seen the Hahn article yet, for those that have, does Greg cite actual accident statistics to back up the rumor that AMA sees issues with 2.4?
