Re: Roebling Road -- Helmet question

[John_Torello@domain.elided]

This info comes directly from the Snell website (www.smf.org)
for anyone interested in the differences between the motorcycle and auto
racing helmet applications

"What are the differences between the SA and M standards?
 SA Standard was designed for auto racing while M Standard was for
motorcycling and other motorsports.
There are three major differences between them:
(1) SA standard requires flammability test while the M standard does not;
(2) SA standard allows narrower visual field than M standard (Some SA
helmets may not be street legal);
(3) SA standard has rollbar impact test while M standard does not. "

Hope this helps
