Expertly designed, the Tech-Air® 3 V2 Leather System is Alpinestars’ motorcycle airbag system for road riders, with over‑ or under‑jacket wear. Featuring AI crash detection with six sensors and Category II PPE Level 2 chest and back protection, it inflates in milliseconds to reduce up to 95% impact energy. Premium softened leather and a sealed ECU enable all‑weather use, while the packable design adds everyday comfort and convenience.
Key Features
Autonomous airbag system: Tech-Air® 3 V2 Leather System works independently without external bike connections or sensors, so you can ride protected on any motorcycle.
Integrated sensor suite: 6 onboard sensors (triaxial accelerometer and gyroscope sets) deliver precise crash monitoring across dynamic riding situations, even when stopped.
AI crash detection algorithm: Intelligent deployment logic accurately decides when to inflate for active protection in street scenarios and varied conditions, including at a standstill.
Magnetic zip activation: Simple closure automatically arms the System, making readiness effortless before every ride.
Packable design: Slim vest compresses to store in a backpack, saddlebag, top case, or pannier when not in use.
Functional storage and adjustability: Right‑chest sunglasses pocket, glove loop at waist, elasticated side panels for comfort and expansion volume, plus an option to neatly fold and button away the airbag bladder for convenience.
Pocket layout: 2 zippered hand pockets, 2 zippered chest pockets, and an inner pocket keep essentials organized and secure.
Customization openings: Dedicated areas let riders add patches or embroidery to personalize the vest without affecting function.
Status interface with LED and haptic alerts: LED in the left chest pocket (with reflective backing) shows operational status, while vibrations confirm arming and warn of low battery for clear feedback.
Back protector pocket: Integrated compartment allows the addition of passive back protection for layered safety.
Compact ECU placement: Alpinestars’ Pro Second Generation ECU sits in an upper‑back pocket for sleek integration and balanced weight distribution.
App connectivity (BLE 5.0): Pair with the Tech‑Air® App to check system and battery status and view detailed ride maps via MyRide for enhanced insight.
Software updates: Manage and install the latest System software through the Tech‑Air® App to keep performance current.
Long‑life battery: Integrated lithium‑ion battery offers up to 40 hours of active ride time; about 4 hours to full charge, or roughly 8–10 hours from a 1‑hour top‑up, minimizing downtime.
Inflator location: Gas inflator sits in a housing at the rider’s left lower back for protected, accessible placement.
Removable components: Inflator housing, electronic wiring, and airbag are easily removable to simplify maintenance.
Serviceable consumables: Inflator canisters can be replaced by select Alpinestars dealers and certified Tech‑Air® Service Centers to keep you riding.
Care and cleaning: Vest is not washable; wipe with a damp cloth and refer to the User Manual for detailed maintenance to preserve performance.
