What is CMR Homologation? A Guide for Kart Racers and Parents

If you're buying a helmet for karting, you'll see the term CMR on approved helmets. Here's what it means, why it matters, and how to choose the right helmet.

What Does CMR Stand For?

CMR stands for Casque Moto Racing — the FIA's homologation standard specifically developed for racing karts. The current standard is CMR 2016, introduced to replace the older CMS standard and bring karting helmets in line with modern impact protection requirements.

Why Does Karting Have Its Own Standard?

Karting presents a unique set of safety challenges compared to circuit racing in closed cars. Kart drivers sit much closer to the ground, are exposed to debris, and experience different impact dynamics than car racers. The CMR standard is specifically engineered for these conditions — it is not simply a lower version of FIA 8860.

A helmet homologated to FIA 8860-2018 is not automatically approved for CMR-regulated karting. You need a helmet specifically homologated to CMR 2016.

Which Schuberth Helmets Are CMR Homologated?

Schuberth produces two CMR 2016 helmets:

• SK1 Hybrid — carbon/composite hybrid shell, excellent value for serious kart racers
• SK1 Carbon — hand-laid autoclave-cured carbon fibre shell, the premium option

Both are approved for racing kart use in CMR-regulated series.

Who Needs a CMR Helmet?

If you are competing in any of the following, you need a CMR-homologated helmet:

• CIK-FIA karting championships
• National karting series (most require CMR 2016 or equivalent)
• Club karting events where FIA homologation is required

Always check your specific series regulations — some club events accept a broader range of standards, while national and international events will specify CMR 2016.

CMR vs CMS — What's the Difference?

The older CMS standard has been phased out in most regulated series. If you have an older helmet with CMS homologation, check with your series organiser whether it is still accepted. For any new purchase, CMR 2016 is the correct standard.

Sizing for Junior and Adult Drivers

Both the SK1 Hybrid and SK1 Carbon are available in sizes from XXS (52–53 cm) through L+ (59+ cm), covering junior drivers through to adult and gentleman drivers. Schuberth uses two shell sizes to maintain the correct proportions across the size range.
