D-air® Racing recognises and intervenes

D-air® Racing is designed to provide its additional protection in track use, recognising and activating in the event of:
- Loss of front or rear wheel traction followed by rider rolling (lowsider).
- Rider thrown from bike as a result of rear wheel slide followed by sudden recovery of traction (highsider).

A sophisticated activation algorithm

In the event of a violent crash, D-air® can trigger in less than 15 milliseconds. When the crash dynamics are less sudden, the sophisticated triggering algorithm assesses conditions and can decide upon a longer triggering time.
The D-air® racing airbag has a deployment time of 30 milliseconds (In accordance with pr EN 1621-4) and reaches its full protection level within 80 milliseconds.

Intelligent protection

Thanks to its intelligent triggering algorithm, D-air® Racing can assess the violence of a crash and only trigger when actually necessary in the scenarios considered above. It won't, for example, trigger in falls at speeds of less than 50 km/h or when the crash dynamics don't require the extra protection of an airbag.

Technical features

D-air® Racing consists of an electronic system (hardware, triggering algorithm and management software), a pneumatic system (gas generator and airbag) and a support structure that is purpose-designed for its intended use (in this case racing leathers), where the different components are safely and reliably installed.
