D-air® Street is the Dainese airbag designed for use on the road. D-air® Street works without any physical connection to the motorcycle and comprises two systems - one that’s installed on the bike, called M-kit, and one that’s fitted in the jacket, called J-kit. This architecture enables rapid crash response times and effective protection throughout the dynamics of a road accident.

WHAT D-AIR® STREET PROTECTS D-air® Street works in synergy with a Dainese back protector to shield the following areas of the rider’s body:

  • 1 BACK

    The system brings riders and pillions the extra back protection of an airbag that’s certified to the current EN 1621-2 standard.

  • 2 COLLAR BONES

    D-air® Street limits inclination of the head in relation to the neck and reduces helmet movement during rolling.

  • 3 CHEST

    D-air® Street extends around the front of the rider's body to protect up to the chest.

HOW EFFECTIVELY D-AIR® STREET PROTECTS

Limit specified by standard en 1621-2 for back protectors Traditional composite back protector D-air® Street

-72%

Tests carried out in accordance with the current European Standards for back protectors (EN 1621-2) show that D-air® Street reduces the impact forces transferred by compared with traditional level 2 back protectors.

WHEN D-AIR® STREET PROTECTS

D-air® Street protects riders and pillions on the road, recognising and activating in the event of:

CRASHES INTO FIXED OR MOVING OBJECTS

In the most violent crashes, D-air® Street has a Total Deployment Time of 45 milliseconds.

CRASHES DUE TO LOSS OF TRACTION

In the event of a skid, the sophisticated triggering algorithm can decide upon a longer triggering time.

Thanks to its intelligent triggering algorithm, D-air® Street can assess the violence of a crash and only trigger when actually necessary in the scenarios considered. It won’t, for example, trigger for impacts at speeds of less than less than 7 kph.

D-air® Street comprises M-kit and J-KIT.
  • Electronic system cover
  • Airbag
  • Electronic system and batteries
  • Gas generators
  • Electronic system housing
  • Wave back protector

  • Pneumatic system comprising two high-pressure airbags with a total volume of 12 litres and two cold-technology gas generators.
  • Electronic system for dialogue with central unit and inflation.
  • SIM card slot for system recognition.
  • Batteries.
  • On/Off switch and fault alert vibration motor.

The M-kit consists of:

  • 2 - A central signal processing and system management and monitoring unit with user interface display.
  • 3 - A pair of three-axis accelerometers mounted on the front fork (one on each leg).
  • 4 - A skid sensor mounted under the seat.

The sensor unit, which is implemented in a double redundant configuration in accordance with critical safety standards, sends the measurement signals to the electronic unit which features:

  • A CPU with the triggering algorithm software, the brain of the system.
