Moto2: Simoncelli first at deploying D-air

Marco Simoncelli yesterday became the first motorcycle racer to have taken advantage of an air bag system integrated into his leathers when he crashed off his Gilera 250cc bike at Valencia

The Dainese D-air is an independent system solely carried on the rider that comprises of three accelerometer, three gyros and a GPS system all fully enclosed into the rider's aerodynamic 'hump' on his back.

When these sensors sense a low side or high side, the system deploys by using software that took three years to write.

A small battery powers the device that then can inflate the 37-litre air bag in less than 40 milliseconds.

Cleverly, so far as motorcycle racers are concerned, should the device deploy and the rider is not injured, nor his bike damaged, the system can be detached, enabling the rider to continue racing.

Tests were initially done using a stunt rider (pictured).

Like the advent of full face helmets and back protectors, this new device may well be adopted in everyday motorcycle racing.

Dainese are continuing development for road usage.
