Alpinestars Tech‑Air® Off‑Road Airbag – professional airbag protection for enduro, rally and extreme off‑road riding
The Tech‑Air® Off‑Road System represents the pinnacle of Alpinestars’ airbag development for off‑road, enduro and rally riding. Refined through years of testing in the world’s harshest competitive environments, including the Dakar Rally since 2017, the system is engineered to deliver maximum protection in terrain where unpredictability, high speeds and long stages place unique demands on rider safety. Fully FIM‑homologated and certified under multiple European standards, the Tech‑Air® Off‑Road is designed for riders who require uncompromising performance and reliability.
The airbag provides CE Level 1 coverage for the chest, back, shoulders, collarbones and neck, offering significantly greater impact reduction than traditional passive protectors. The system is certified for ENDURO, RALLY and STREET performance under Dolomiticert protocols, ensuring that it performs consistently across a wide range of off‑road and mixed‑terrain scenarios.
Advanced crash detection engineered for off‑road terrain
At the heart of the Tech‑Air® Off‑Road System is a fully self‑contained sensor suite housed within the Electronic Control Unit (ECU). The ECU integrates accelerometers and gyroscopes that continuously analyse rider movement, terrain feedback and dynamic forces. Because the sensors are internal, the system requires no external components or installation on the motorcycle.
The detection algorithms are specifically trained for off‑road riding, where impacts, jumps, harsh landings and irregular surfaces are part of normal operation. By distinguishing between expected off‑road forces and genuine crash events, the system ensures accurate deployment only when needed. With an average inflation time of approximately 52 milliseconds (size dependent), the airbag inflates before the rider contacts the ground, providing critical protection in high‑risk situations.
Three ride modes – ENDURO, RALLY and STREET
To deliver optimal performance across different riding environments, the Tech‑Air® Off‑Road System offers three selectable ride modes:
- ENDURO: tuned for technical terrain, low‑speed manoeuvres and frequent impacts.
- RALLY: calibrated for high‑speed stages, long distances and aggressive riding.
- STREET: optimised for everyday road riding and mixed‑surface travel.
Modes are selected via the LED display, and the system automatically adapts its detection behaviour to the chosen environment.
Dual‑charge inflators and user‑replaceable cartridges
The Tech‑Air® Off‑Road System features dual gas inflators, allowing two independent deployments before servicing is required. This is essential for multi‑day events, long rally stages or remote expeditions where immediate access to service facilities may not be possible. The airbag itself is certified for up to four deployments in total, provided it remains undamaged.
Where permitted by local regulations, the inflators can be replaced by the user, enabling rapid turnaround between rides and ensuring minimal downtime during competition or training.
Comfort engineered for long‑distance riding
The chassis is constructed from breathable stretch‑mesh with open‑structure panels that promote airflow and help regulate body temperature during long and physically demanding stages. The ergonomic pattern is designed to sit close to the body without restricting movement, while additional roost padding on the arms and chest enhances comfort in group riding and competitive environments.
An internal hydration bladder sleeve supports reservoirs from 1.5 to 3 litres, making the system ideal for rally and endurance riding where hydration is essential.
Electronics, durability and battery performance
The sealed electronics enclosure is built for all‑weather use and is certified to operate between −10°C and +50°C. The system meets ECE R10 04 requirements for electromagnetic compatibility, ensuring reliable performance even in electrically noisy environments.
The long‑life battery provides up to 30 hours of operation, and the USB‑C charging interface on the LED display delivers a full charge in approximately four hours. A one‑hour top‑up provides around eight hours of ride time, making the system practical for multi‑stage events.
A dedicated Shipping Mode disconnects the battery for air travel or long‑term storage, protecting the system and preserving battery health.
