What helmet is required for BMX racing?

Under the 2026 BMX racing regulations:

• Every rider must wear a helmet meeting AS2063/NZ 2063 or an accepted equivalent (NSI Z90.4, Snell B or N series, ASTM F1447, Canadian CAN/CSAD113.2M, US CPSC or European EN1078). It must carry the manufacturer's mark stating it complies, and a Commissaire may inspect it at any time.
• Full-face helmets with a fixed non-detachable mouthpiece are mandatory at all AusCycling sanctioned events.
• If a rider's helmet comes off for any reason between the start of a heat or run and the finish line, the rider is considered to have abandoned the heat or run and is scored Did Not Finish (DNF).
