My motorcycle instructor when I first got my license said if you don't drink, if you ride below your limit and you wear a helmet, your likelihood of dying on a motorcycle is almost zero. This was possibly an experienced rider but they were drinking and she wasn't wearing a helmet and if she leaned against the bike as the rider says she did, she wasn't given proper instruction on how to be a rider. You don't just let someone hop on your bike without knowing some basic principles. Tragic. The rider was at fault here.
