Functionality & Safety
The Tech-Air® MX provides comprehensive airbag protection for the shoulders, chest, and back, and delivers more than four times the impact protection of conventional passive protectors. The CE-certified airbag (Category II, EN1621-4:2013) fully deploys within 40 ms to 5 s after an impact. The system is certified for up to six deployments, provided the airbag remains undamaged. Active protection is complemented by a CE Level 1 chest and back protector with adjustable straps for a perfect fit. Three accelerometers and three gyroscopes in the ECU ensure precise crash detection even under dynamic MX conditions.
Transport & Storage
A transport lock switch on the ECU puts the system into sleep mode. This completely disconnects the battery from the system – for air travel, long-term storage, or shipping. Upon delivery, the airbag system is in shipping mode and must be activated before first use (by operating the switch).

The Alpinestars Tech-Air® MX is one of the most advanced airbag systems for motocross and supercross. Compact, lightweight, and autonomously integrated, it offers fast, precise protection for the upper body, shoulders, chest, and back. With its customizable riding modes, advanced sensor technology, and CE-certified protection, it is the ideal choice for off-road riders who want to combine maximum safety with unrestricted freedom of movement and versatility on any track.
