Holmes, Jim,
You do do raise some good points here in our discussion, and you seem very knowledgeable about the sport of MC riding, and while I may not be 100 percent correct on everything, I am a dare devel, and a risk taker, and have had a great time engaging these kind of activities.
If you get Additional information on the safety of our sports, please post it here, sometimes I think industries who are against motorsports of all kinds come up with things. Even Mark Twain, distrusted statistics, and that was in the 19th century.
If you still ride, stay safe. I think any two wheel activity is risky, and with that the fun.
Best,
Holmes Red LED
