Alpinestars Tech-Air® 5 PLASMA Airbag System

Ultra-Light Motorcycle Airbag Protection for Street, Adventure & Race Riding

Advanced Protection You Barely Notice

The Alpinestars Tech-Air® 5 PLASMA is an ultra-lightweight autonomous motorcycle airbag system engineered to provide comprehensive upper-body protection while maintaining exceptional comfort, flexibility, and airflow.

Its slim profile is designed to fit discreetly beneath compatible motorcycle jackets, while the anatomically shaped airbag provides coverage around the chest, ribs, back, and shoulders.

With dedicated Street, Adventure, and Race riding modes, an integrated Nucleon PLASMA back protector, and a user-replaceable gas canister, the Tech-Air 5 PLASMA brings Alpinestars' latest airbag technology to everyday and performance riding.

Comprehensive Airbag Protection

The Tech-Air 5 PLASMA uses an anatomically shaped airbag designed to maximize protection while minimizing unnecessary bulk.

Protection Areas:

• Chest
• Ribs
• Back
• Shoulders

Strategically positioned cutouts allow the system to follow the contours of the rider's body while maintaining a broad protection area.

Street, Adventure & Race Modes

One system is designed to adapt to different styles of motorcycle riding.

Riding Modes:

• Street
• Adventure
• Race

Each mode uses a dedicated crash-detection algorithm developed for the specific riding environment.

Select the appropriate mode and the system continuously monitors your riding to determine when airbag deployment is required.

Ultra-Light & Low-Profile Design

The Tech-Air 5 PLASMA is engineered to feel almost invisible underneath your motorcycle jacket.

Comfort Features:

• Ultra-slim construction
• Lightweight design
• Highly breathable chassis
• Flexible fit
• Minimal use of rigid plastic components
• Designed for excellent freedom of movement
• Approximately 1,530 g system weight

The result is serious protection without the bulky feeling traditionally associated with protective equipment.

Integrated Nucleon PLASMA Back Protector

The system incorporates Alpinestars' Nucleon PLASMA back protector, providing passive impact protection in addition to the airbag system.

PLASMA Benefits:

• Slim profile
• Flexible construction
• Highly ventilated
• Designed to move naturally with the rider
• Integrated directly into the airbag system

The combination provides both conventional impact protection and electronically activated airbag coverage.

Designed for Maximum Airflow

An ultra-thin stretch mesh chassis helps keep material mass to a minimum while maximizing ventilation.

Ventilation Features:

• Highly breathable stretch mesh construction
• Ventilated collar and underarm areas
• Open front-panel ventilation zones
• Reduced material layering
• Designed to align with compatible jacket ventilation systems
• Optimized for warm-weather and active riding

User-Replaceable Gas Canister

The Tech-Air 5 PLASMA uses a single-charge deployment system with a gas canister that can be replaced by the rider.

This helps simplify getting the system ready to ride again following a deployment, provided the airbag and system remain within their specified service limits.

The airbag is certified for up to six deployments before replacement is required.

Intelligent Electronic Protection

The Tech-Air 5 PLASMA continuously analyzes rider movement through its electronic crash-detection system.

The system operates independently without requiring a physical connection to the motorcycle.

This gives riders the freedom to use the system across compatible motorcycles without installing sensors or electronics on each bike.
