Icala elingaphakathi le-helmet kufuneka lixhotyiswe nge-liner-resistant-resistant liner. Umgca kufuneka ube ne-ventilation groove enobunzulu obungaphezulu kwe-10 mm ukuqinisekisa ukujikeleza komoya kwisigqoko. Umphezulu womzimba yi-5 mm, kwaye unovakalelo olulula kwaye olukhululekile xa unxibe i-helmet. Ayigxininisi, ibala elibanzi lombono, licacile kwaye alinasiphazamiso, kwaye intsimi yembono ye-angle ayikho ngaphantsi kwe-105 ° kwisimo esimileyo.
Ubunzima be-helmet akufanele budlule i-2 kg. Xa unxibe isigcina-ntloko, unokuva ngokucacileyo kwaye ukwahlule izandi ezivela macala onke. Isigcina-ntloko kufuneka sibonakalise kwaye simelane nemitha yobushushu, kwaye sikhuseleke eluthulini, singangeni manzi kwaye sikhuseleke kwizinambuzane. I-lens yesigqoko kufuneka icace kwaye ingabi mbala, ibe nobunzima obuhle kwaye ingabi lula ukuyiphula.

Amapolisa ezendlela akhumbuza: Xa isithuthi esinamavili amabini sibandakanyeka kwingozi, intloko yenye yezona ndawo zisengozini yomqhubi kunye nomkhweli. Ngoko ke, ukongeza ekuthobeleni imithetho nemigaqo, kufuneka kwakhona ukhumbule ukunxiba izigcina-ntloko zokhuseleko ngokuchanekileyo xa uhamba ngesithuthuthu okanye ngebhayisekile yombane ukunqanda iingozi.
