Le mie ricerche di un casco con look classic si sono sempre scontrate con i divieti e le paure legate all'omologazione. Ho trovato proprio sul forum RAT UK una lettera spedita da una rivenditrice di DAVIDA ad "uno di noi" che chiedeva proprio nformazioni sull'omologazione dei caschi...
Ho pensato potesse interessarvi...
Se poi qualche "anglofono" avesse la pazienza di tradurre la lettera farebbe un grande favore!!
Thank you for writing. Helmet manufacturers actually build a helmet to meet the standards of the certification entity of their target market. Most helmet safety certifications are best described as a collection of ‘standards’ that often have little to do with ‘real life’ safety. For example U.S. D.O.T. 218 certification requires a helmet to pass a ‘spike drop’ test. Basically a steel spike is dropped from a measured distance on the very top / center area of a helmet and tip of the spike must not extend through the polystyrene shock absorbing liner to pass the test. A totally absurd requirement as the chance of getting ‘spiked’ at the very top of the helmet is slim at best. Most manufacturers comply by simply putting a pad of some dense material at the very top of the helmet where it is (in my opinion) otherwise useless.
To answer your questions to the best of my ability; I do not know the letter of Nordic Safety Standards SIS 882411 and DS 2124.1 to which the Speedster is built. I can tell you that the shell material (fiberglass composite) and thickness is the same as in the D.O.T. certified Davida Classic Jet. The Speedster also uses the same molded polystyrene shock absorbing liner material as the Classic Jet, but it is a bit thinner (about ¾” vs. 1” in the CJ). Although the Davida Classic Jet is the most compact D.O.T. open face helmet available I personally prefer and ride with a Speedster as it is even more compact and lighter yet offers (in my opinion) a high degree of safety for my valuable head. I wear a size small helmet so I don’t care for the ‘mushroom head’ look either.
In a nut shell, to the best of my knowledge the European ECE R22-05 certification is the most stringent, followed by the unofficial Snell, followed by D.O.T., followed by SIS & DS (Speedster) and finally the Japanese and other standards. I hope I have been of some assistance!
P.S. ho scoperto che lo standard DS 2124.1 risale al 1975.........
