Developed over a decade, the Tech-Air® MX System is Alpinestars’ most advanced off-road airbag for motocross and supercross. Featuring AI-powered crash detection and four selectable Riding Modes, it provides CE Category II airbag protection compliant with EN1621‑4:2013, covering shoulders, chest, and back with inflation in ~40 ms. Integrated Nucleon PLASMA back protector, breathable stretch-mesh vest, LED display, and up to 30-hour battery enhance comfort, control, and uptime.
Key Features
- Multiple Riding Modes: Default MX Mode plus dedicated MX RACE, ENDURO, RALLY, and DOWNHILL profiles, selectable via the Tech-Air® App or onboard controls, allowing protection to adapt to different riding disciplines, speeds, and terrains.
- AI Crash Detection: Machine-learning tuned with elite MX/SX ride data to recognize crash dynamics accurately, helping deliver protection when it matters while minimizing nuisance inflations.
- Active Airbag Response: Rapid inflation engages during the crash sequence to absorb impact energy before major contact, supporting confidence over jumps, rhythm sections, and rough terrain.
- System Versatility: Low-profile chassis designed to be worn over or under MX gear; single gas inflator enables one deployment and is easily replaceable where permitted to reduce downtime.
- Battery Life: Up to 30 hours of ride time per charge, with a 1-hour quick charge adding around 8 hours, keeping you covered through race weekends and training days.
- Quick Activation: Automatic power-on/off via the left buckle sensor for simple, glove-friendly operation in the paddock and on the grid.
- Bluetooth Connectivity: Tech-Air® App support for status checks, Riding Mode management, and wireless diagnostics to keep your Tech-Air® MX System ready to ride.
