As stated on the Snell Foundation’s website, the main difference between these standards are as follows: “The SA standard is designed for competitive auto racing. The M standard is for motorcycling and other motorsports. The K standard is issued to accommodate helmets used in karting. There are two major differences among 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. This means that some SA and K certified helmets may not be street legal.“
Please note, Youth Helmets are designed for racers under the age of 15 and should not be worn by adults. Sizing for youth helmets is down to the shell size of the helmet and this differs greatly between the Youth CMR Helmets and the adult helmets. As such a 57cm Youth Helmet will not fit the same as a 57cm adult helmet. We therefore WOULD NOT ADVISE buying a Youth CMR helmet if you are over the age of 15.
That being said, for younger drivers who have grown out of their 57cm Youth Helmet, we suggest that you will require an ADULT size SMALL helmet.
Which helmet do I need?
Answer: Check with your event organiser on the standard of helmet required as they can differ. Any helmet with the FIA 8859-2015 standard inside will be suitable for the majority of national motorsports, unless the higher FIA 8860 standard is stipulated as a requirement. These are only generally required for FIA sanctioned series’ which are at the highest level of motorsport.
What happens if my new helmet from Zamp Helmets doesn’t fit?

Will my helmet last longer if it is Snell SA2020 rather than Snell SA2015 if both helmets also have the FIA 8859-2015 approval?
Answer: No. The Snell SA2015 or SA2020 standard only really has relevance in the USA. The FIA 8859-2015 approval overrules the Snell approval for national and the large majority of international motorsport today. In fact, several manufacturers today produce their helmets with just the one FIA 8859-2015 safety standard.
Can I fit HANS/FHR posts myself to my current, but in date helmet?

Can I use an ECE approved helmet for motorsport?
