Airbag publicity has blown up recently, but I’m not holding my breath for more independent research. There’s a longstanding lack of itThe Spin Doctor wrote: ↑Sat Dec 03, 2022 11:53 am There's a lot of pro-airbag publicity but I haven't seen the IoM races getting any safer over the last decade!
In MotoGP, collarbone injuries have declined since airbags arrived. But the IoM races must be a more relevant test bed for road riding — albeit, IoM speeds may be too high for regular road crash relevancy.
Regarding regular riders, not all airbags are created equal. Some systems provide relatively comprehensive coverage (e.g. Helite, Astars Tech-Air Race and Street). Others only protect the chest.
Protection varies, too. How many systems achieve CE Airbag Level 2? Unusually for Dainese, I think it might be the only manufacturer with Level 2 airbags (e.g. the Racing 3 D-Air jacket).
