Alpinestars Tech-Air 5 Airbag System

Alpinestars Tech-Air 5: Intelligent Protection for the Modern Rider

The Alpinestars Tech-Air 5 Airbag System represents a monumental shift in motorcycle safety technology. While traditional armor protects against abrasion and localized impacts, the Tech-Air 5 provides an active, inflatable shield that deploys before the rider even touches the ground. This autonomous vest requires no physical tether to the motorcycle and no GPS signal to function, making it incredibly easy to use across multiple bikes. The system utilizes an array of three gyroscopes and three accelerometers that feed data into a sophisticated AI algorithm. This algorithm is the result of decades of data collection from the world’s fastest racers and millions of miles of real-world street riding. Whether you are a daily commuter on a 300cc naked bike or a touring enthusiast on a 1250cc adventure rig, the Tech-Air 5 is designed to be your silent guardian.

Rapid Deployment and Comprehensive Coverage

The primary advantage of the Tech-Air 5 is its speed and coverage area. Upon detecting a crash—whether it is a low-side, high-side, or a collision while stationary—the system inflates in approximately 20 to 40 milliseconds. Once fully deployed, the airbag covers the rider’s full back, shoulders, chest, and ribs. This coverage is critical, as shoulder and rib injuries are among the most common and difficult to treat for motorcyclists. The impact absorption is so efficient that it reduces the force transmitted to the body by up to 95% compared to standard passive armor. To put that in perspective, a deployed Tech-Air 5 offers the protection equivalent to 18 individual CE Level 1 back protectors stacked together, all while remaining slim enough to be worn comfortably under your favorite riding gear.

Expert Fitment & Maintenance Advice

As certified safety experts, we cannot stress enough the importance of the “4cm Rule.” Pro Tip: To allow the airbag to inflate properly, there must be approximately 4cm (1.6 inches) of extra space around the circumference of your chest within your outermost jacket. If your jacket is too tight, the airbag cannot expand to its full protective volume, which could lead to restricted breathing or broken ribs from the pressure of the bag itself. Operation Note: The system is “armed” simply by zipping up the vest and closing the magnetic flap. The LED display at the bottom of the vest provides an instant visual confirmation of battery life and system readiness. Post-Deployment: After the system has deployed, the vest must be sent to an authorized Alpinestars service center for a full inspection and a recharge of the argon gas canisters. We recommend a full service every two years or 500 hours of riding to ensure the sensors and internal battery remain in peak condition.

The Ultimate Investment in Rider Safety

Choosing the Alpinestars Tech-Air 5 is an investment in your physical well-being. It brings the same cutting-edge AI technology used by MotoGP champions to your local roads. For the rider who refuses to compromise on safety, the Tech-Air 5 Airbag System is the definitive choice. It combines ease of use with the highest level of impact protection ever offered in a wearable format, ensuring that you can ride with total peace of mind, no matter where the road takes you.

Fitment Note: Compatible with all Alpinestars Tech-Air Ready jackets. For other brands, ensure the 4cm chest clearance is available. Not recommended for aggressive off-road or motocross use.

Alpinestars Tech-Air 5 System

Tech-Air 5 is a slim, self-contained wearable airbag vest designed to be worn under practically any jacket! The state-of-the-art Tech-Air 5 System features six integrated sensors (3 gyroscopes and 3 accelerometers) to continuously monitor the rider’s position. An algorithm developed closely with MotoGP race data and data from over 2,000 lab-simulated crash scenarios determine when and how the system deploys. The airbag has a maximum inflation time of up to 40ms (or less, depending on vest size). The impact absorption while wearing the airbag results in a decrease of impact force by up to 93% compared to a passive protector. Inflation time is quick enough to deploy the airbag before the rider’s first impact with an obstacle.

The airbag has a battery life good for 30 hours of riding time on a single charge, and an LED display conveniently shows system status directly on the garment. The system features Bluetooth connectivity to pair with the Tech-Air App, which uses the rider’s phone to display the system’s operational status, battery status and provide detailed analysis of a ride. Over-the-air firmware updates are also handled through the app. Alpinestars includes a micro USB charger for quick recharging.

Electronics System:

• Active electronic system that features six triaxial integrated sensors (3 gyroscopes and 3 accelerometers)
• Crash algorithm that leverages AI to accurately monitor when to deploy the airbag in the event of a crash
• 30 hours of riding time after a full charge via micro USB charger
• Bluetooth and App integration
• Capable of both Race and Street use

Airbag System:

• Covers shoulders, chest, ribs and full back
• Maximum inflation time of 20-40ms based on the volume of the airbag size
• Decreases impact force by 93% compared to a passive protector
• Includes argon gas canisters
• Highly ventilated back protector
• Leave elbow and shoulder armor in your jacket, but removing the jackets back protector is recommended (since the Tech Air 5 has one built in)

Operation:

• Zip up vest and close magnetic flap
• Integrated LED display indicates operational status

Washing Care:

• Do not submerge in water
• Spot clean with a microfiber cloth
• Use cold or room temperature water, add mild detergent (ex. Woolite), submerge microfiber cloth, squeeze out excess water, proceed to spot clean the following areas:
  • Left and right inner liner
  • Neck collar
  • Back area
• Avoid the front clasp sensor and ACU on the back where the electrical ports are
• Hang dry in ventilated area, away from sunlight
• Anti-microbial athletic cleaners are an alternative option

Sizing Note: Tech Air 5 should only be worn UNDERNEATH a properly fitting Alpinestars Tech Air ready jacket or any jacket with 1.57″ (4cm) of space around the circumference of the rider’s chest.
