Well, auto helmets are typically...
more expensive
have smaller eye ports
have nomex lined interior ( see the pale yellow coloured strap as clue )
have a thicker 3mm thick visor
a clip on the visor for a more secure closing
possibly have less ventilation openings on some models
and most often comes in white colour only....
Bike helmets have opposite of the above although maybe some higher end nike helmet models are not cheap either.
More important, choose one which fits ur end and make sure u know how to strap it safely....dun laugh, I have seen a kid's helmet fly off at impact....
Why have 300hp when you cannot handle a kart's 30hp?
