Dainese’s D-air Racing systems focus on protecting collarbones and shoulders. They deploy on highsides, and lowsides if the wearer starts to roll. The D-air Road system also protects the chest and detects lowsides with or without rolling, highsides, head-on and lateral (T-bone) collisions. Dainese’s Street airbags use an ‘M Kit’ – four sensors on the bike that recognise crash conditions and order the ‘J kit’ – an airbag gilet – to inflate. Alpinestars’ Tech-air also comes in two versions: Street and Race. Both are designed to deploy in the event of impact, collision or loss of control, and they cover the back, collarbones and chest.
