It would have a cord coming from the helmet to the bike for power would be the only problem I see from a race perspective. Other than that it has the standard D ring attachment and meets ECE 22-05 safety standard so even with that big brick on the back it seems to pass the crash tests.

How much cooler will the Feher helmet be than my regular helmet?
The Feher ACH-1 helmet is not designed to give you an “ice cream headache” or create a cooled environment around your face like when riding in a car. It is designed to reduce the interior temperature around your skull during hot rides compared to using a traditional helmet. That temperature variance will be more significant in higher temperatures and can be up to ten to fifteen degrees cooler. Keeping your head cooler will make your body feel less impacted by the heat and make for a more comfortable ride in hot conditions than riding with your regular helmet.
What powers the Feher air conditioning unit?
The Feher helmet is powered by your motorcycle battery. It comes with the necessary harness to connect to the battery and a quick disconnect cord with a switch. It is also possible to power the unit with battery packs that can be purchased separately online.
On a separate note the Rule book states helmets need to meet ECE 22.05 "P" standards, that P standard only applies to the modular flip up helmets to denote the chin guard is designed to provide some protection. Do we even allow modular flip up helmets?
