I was forwarded some information from the Washington DOL and encouraged to share it, so here goes:

I think there is a lot of good information here.

Very interesting data, some of which I haven't seen compiled before.

The unique climate of Washington permits a measure of motorcycling exposure--dry days per month--that helps understand variations both within a year and between years.

60% of newly endorsed riders are trained. But among endorsed riders killed, only 41% were trained. This suggests a significant benefit of training. However, the percentage of trained riders among all endorsees (not just the noobs) isn't reported, so the question is open.

As Hurt and MAIDS both found, experience is a highly significant factor in reducing crash risk. Comparing experience (presumably via years endorsed) for riders in fatal crashes vs. all Washington endorsees in 2012, riders with < 3 years experience were overrepresented by a factor of 2. Riders with more experience were approximately equally underrepresented--i.e., the 3-5 year group was about the same as the 21-year+ group. However, this was only one year of data. It would be nice to see a 5- or 10-year compilation.

The "years endorsed" chart (p15) sheds light on the question: How long do riders stick with motorcycling? 44% of endorsees have 0-5 years experience (again, presumably years endorsed), 25% have 6-10 years, 8% have 11-15 years, 6% have 16-20 years, and 16% have 21+ years. There is a substantial self-driven "weeding out". This may help to explain the benefit of experience mentioned above: More experienced riders may be less likely to crash in part because they have demonstrated to their own satisfaction an aptitude for motorcycling.

A positive development in Washington seen in the data I have collected, but not reported in the document, is the falling rate of fatalities per 100,000 registered motorcycles. According to US DOT data, the rate in Washington has fallen by 25% over the past 10 years
