For karting, a Snell/FIA CMR or CMS youth helmet, or one rated SFI 24.1. Our 2026 karting rules guide shows SKUSA, USPKS, WKA and AKRA accepting all three, and SKUSA, USPKS and AKRA list CMR and CMS as valid for 10 years from the manufacture date. Age and class rules vary, so check your rulebook before you buy. Shop youth and kids karting helmets.
