I'm not sure what's going on with the helmet issue in the US but a suomy doesn't carry snell in OZ so you can't where them in Drag Racing as they only recognise Snell for Group 1 motorcycles, problem here is the rest of the countries motorcycle groups don't recognise Snell , so the manufacturers of High End motorcycle helmets don't build the helmets to or pay snell for certification, So a top of the line European or Asian Helmet usually only carries British or Australian Standard, which caters for almost every quality of helmet,,,here
It would be good if we had an international recognised helmet standard just for racing purposes,
My expensive non compliant helmet is certainly a much better helmet than my compliant one...
My other argument is no one ever checks if the helmet you present to scruteneering actually fits your cranium, I can recall a Famous Australia Racing Car driver pull a lose helmet off over the top of his glass's for a television interview at the end of a race,
My point being is the best helmet in the world ain't going to save you if it don't fit your head, I've seen many racers share helmets before,,,
