Helmets should fit according to the manufacturer�s specifications.  Helmets must be worn and properly fastened during all track sessions. Damaged helmets may be refused at any time. The helmet visor must be in the down (closed) position any time a kart is in motion.

Modifications: No helmet may be modified from its specification as manufactured, except in compliance with instructions approved by the manufacturer and one of the FIA listed standards organizations, which certified the model concerned.

Any other modification will render the helmet unacceptable for the requirements of the present article.

HANS devices or similar devices are not allowed for kart racing.

Maximum Weight: The weight of helmets may be checked at any time during an event and must not exceed 1800 grams or 1550 grams for Juniors.

Decoration: Paint can react with helmet shell material and affect its protective capacity, therefore, where a manufacturer provides guidelines or restrictions on the painting or decoration of helmets, these must be followed, using only paint specified by them (air drying acrylic, polyurethane enamel or others) and preferably a painter having their approval.

This is particularly important for injection moulded shells which are not usually suitable for painting.

The shell being painted should be efficiently masked as paint penetrating the interior can affect the performance of the helmet liner. Paints requiring heat curing should not be used and any process should not exceed the maximum temperature of conditioning of the helmet in the standard to which it is approved.

The manufacturer's instructions should also be consulted for any considerations on the use of stickers and transfers.

Typical Helmet Design
