Professionally developed, the Tech-Air® 5 System is Alpinestars’ most advanced motorcycle airbag for road riders, delivering autonomous upper‑body protection in a vest. Six sensors and an AI algorithm trigger 20–40ms inflation, reducing impact forces by up to 95% and covering shoulders, chest, ribs, and full back. Worn under textile or leather jackets with 4 cm chest expansion, it offers comfort and confidence; Tech-Air® App enables STREET and RACE (closed‑course) modes.
