What are the differences between the SA, M and K standards? The SA standard was designed for competitive auto racing while the M standard was for motorcycling and other motorsports. The K standard was released to accommodate helmets used in karting. There are three major differences between them: 1.The SA standard requires flammability test while the M and K standards do not. 2.The SA and K standards allow for a narrower visual field than the M standard (Some SA and K certified helmets may not be street legal). 3.The SA and K standards include a rollbar multi-impact test while the M standard does not.
