I think the only difference in SA and MC helmetsd is the SA helmets are fire resistant. I believe they are the same other than that but...I am not 100% sure.The differences are:
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.
