And the most asked question about the ratings.
What are the differences between the SA, M and K standards?
The SA standard was designed for competitive auto racing while 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 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 M standard does not.
