Following more than a decade of rigorous product development, continuous testing, and collaboration with top MX and Supercross athletes, Alpinestars introduces the Tech-Air® MX Airbag System, a groundbreaking addition to its autonomous Airbag technology lineup. Initially utilized and tested in pre-production form by Alpinestars professional racers, the Tech-Air® MX is now available to motocross riders worldwide, ushering in a new era of safety for the sport.
TECH-AIR® MX AIRBAG SYSTEM
Alpinestars has long been a pioneer in airbag protection for motorcycle racing, beginning with the Tech-Air® Race System in MotoGP in 2009, built on data collected from road racing since 2003. Continuous advancements, driven by extensive data from Alpinestars’ global roster of racers, have propelled the Tech-Air® System to new heights. Similarly, the Tech-Air® Off-Road System has set the benchmark for protection at the Dakar Rally since 2019, leveraging data acquired from World Rally Championship racers since 2014.

For Tech-Air® MX, Alpinestars has applied the same meticulous R&D approach, gathering data from AMA Supercross and motocross and FIM MXGP riders since 2016. This data has fueled the development of a sophisticated MX crash detection algorithm capable of rapidly activating airbag protection in the dynamic and unpredictable conditions of motocross, with different type of jumps, ruts, berms, and whoops.

The Tech-Air® MX provides extensive and effective upper body protection in a compact chest protector that comes with an autonomous Airbag System embedded inside. Designed to be worn as a standard part of a rider’s kit, over or under the jersey, the lightweight System ensures convenience without compromising performance.

Activating the Tech-Air® MX is easy; simply attach the left buckle of the System to the Chest Protector, and an internal magnetic switch will detect the left buckle is closed and automatically turn on and activate the Airbag System. Detaching the left buckle will automatically deactivate and turn off the System.

ADVANCED AI AND CRASH DETECTION

The Tech-Air® MX is a fully autonomous, industry-leading Airbag System equipped with six integrated sensors (one triaxial accelerometer and one triaxial gyroscope). These sensors monitor rider movements in real-time, transmitting data to the System’s computer every millisecond—1,000 times per second. Developed and analyzed through thousands of hours of riding and crash data, the System’s algorithm precisely determines when to deploy the airbag before an impact or dangerous riding event.

When a crash event is detected, the Airbag System deploys within 28 to 37 milliseconds, depending on the chest protector size (small to large). The inflated airbag provides impact absorption equivalent to an 82% reduction in transmitted energy compared to conventional passive chest protectors.

The shoulder zones are also protected during deployment, even though in the riding configuration no passive protection elements are present in those areas, allowing full range of motion without restriction under normal riding conditions.

This rapid deployment safeguards the rider’s shoulders, chest, and back, delivering unparalleled coverage.

CUSTOMIZABLE RIDING MODES
Tech-Air® MX comes preloaded with a dedicated MX Mode optimized for motocross tracks. Additionally, it offers two customizable modes—MY RIDE 1 and MY RIDE 2—configurable via the Tech-Air® App. Riders can select from four riding modes (the default MX mode, or MX RACE, ENDURO, and RALLY) tailored to specific disciplines, each with algorithms fine-tuned for crash detection in varied conditions. Riding Modes can be switched effortlessly using the LED display button or the app, providing flexibility for different riding scenarios.

EASY GAS INFLATOR REPLACEMENT
The System includes a quick-release cover for easy gas inflator replacement, with certification for up to six deployments before requiring service, assuming no damage to the airbag.

TECH-AIR® APP AND SYSTEM SOFTWARE UPDATES
Bluetooth connectivity enables seamless software updates via the Tech-Air® App, which also allows riders to monitor System status, battery life, and ride data through an enhanced Google Maps integration (subject to network coverage). A fully charged battery supports approximately 30 hours of active ride time, with an integrated LED display showing operational status, battery life, and selected Riding Mode.

SUPERIOR PROTECTION
The Tech-Air® MX provides CE L1 passive protection for the chest and back, with CE L1 active protection on the back when the airbag is deployed. Certified to Category II of the 686/89/EEC European PPE Directive and EN1621-4:2013, the System guarantees impact protection within 40 milliseconds to 5 seconds of full-pressure inflation, covering the rider’s shoulders, chest, and back.

AVAILABILITY
The Tech-Air® MX Airbag System launches in Europe and international markets on December 11, 2025—available online at alpinestars.com and at authorized Alpinestars dealers.
