About Alpinestars Stella Tech-Air® 3 System

Alpinestars Stella Tech-Air® 3 System

Alpinestars Stella Tech-Air® 3 Airbag System is an ‘over’ the jacket solution for commuters and younger riders and offers effective upper body protection by covering the rider’s full chest and full back, and is equipped with an ergonomically optimized women’s tailored female fit with a tapered cut for enhanced comfort.
Featuring a water resistant man chaisis and a waterproof ECU and electronics, this slim, self-contained system can also be worn under a motorcycle jacket, including any Alpinestars’ compatible jacket, any leather or textile jacket, providing that the jacket has sufficient space to accommodate the inflation of the airbag.
Alpinestars’ crash detection triggering algorithm has been developed and refined with over 2 million kilometers of riding data and over 2,000 crashes, allowing the system to accurately assess when to deploy the airbag ahead of an impact or other dangerous situation like a lowside or highside crash, and in the event that Tech-Air® 3 detects the start of a crash, the system will activate the protective airbag, with an average inflation time of 50ms, depending on the size of the airbag.
