Both must meet the same Snell impact limits. Snell SA2025 adds two auto racing requirements: flame resistance, and metal M6 inserts for HANS / FHR anchors. Snell K2025 tests neither, so a K2025 kart helmet is not certified for car racing. An SA2025 helmet can also race karts where your league allows it. Compare the Bell RS7-K (K2025) and RS7 PRO (SA2025). Shop kart helmets.
