The ALPINESTARS TECH-AIR Tech-Air® 5 Plasma Airbag System is engineered to fit discreetly beneath a compatible motorcycle jacket while providing comprehensive upper-body protection. Its ultra-slim, lightweight profile creates an almost invisible under-jacket feel, allowing riders to maintain freedom of movement without unnecessary bulk. The system protects the chest, ribs, back, and shoulders, making it a practical choice for street, adventure, and performance riding applications.
The Tech-Air® 5 Plasma combines adaptive comfort with advanced impact protection through an integrated Nucleon Plasma back protector. This lightweight, eco-conscious impact-absorbing material is designed to balance force dispersion, flexibility, ventilation, and comfort. The full-stretch construction and moisture-wicking treatment promote airflow and help manage heat, while the ultra-thin mono-layer stretch mesh chassis contours to the airbag for a close, adaptive fit across the collar, underarms, and front of the body.
A dedicated deployment algorithm provides three selectable riding modes: Street, Off-Road, and Race. Once the system is switched on, riders can change modes by pressing the system button for two seconds, with the selected mode shown by a solid green LED. Pressing the LED button also provides a status check, while a vibration confirms that the system is operating correctly. The single-charge deployment design uses one gas canister to help reduce weight and simplify maintenance, and the canister can be replaced by the user.
The quick-release cover attaches to the chassis with a hook-and-loop patch for straightforward access to the gas inflator. A recessed finger grip allows the cover to be lifted and detached when replacement is needed, helping minimize service time. The ALPINESTARS TECH-AIR Tech-Air® 5 Plasma Airbag System is supplied in black and this version is sized small, with part number 6504925-10-S. Always review the manufacturer’s compatibility, operation, charging, and care instructions before use.
