M rated helmets have a larger peripheral vision.

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:

The SA standard requires flammability test while the M and K standards do not.

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).

The SA and K standards include a rollbar multi-impact test while the M standard does not.
