When sourcing AGV helmets, the most critical factor is ensuring they meet the legal safety standards of the destination country. For the US market, DOT (FMVSS 218) is mandatory, while the European market requires ECE 22.06 (the latest, more stringent standard). For professional racing, look for FIM Racing Homologation. Always request official test reports from third-party labs rather than relying solely on stickers to ensure the shell integrity and impact absorption meet international safety benchmarks.
