The Motorcycle Safety Foundation has a very useful library of
downloadable documents, covering subjects such as a pre-ride
checklist, how a helmet works, and the rider handbooks for the MSF
courses. There is also a link to the International Conference on
Motorcycle Safety, which has papers examining topics such as should
you swerve or brake and a comparison of helmet qualifying
standards. This is one link that may save your life.
