Certainly! The D-air® Street system can be replaced following deployment. For more informations and instructions contact us here

D-Air® Street garments (i.e. the Gilet or Gore-Tex® jacket) can be sent to Dainese for an authorised Dainese installer as it is vital to ensure that system is working properly.

Dainese will supply you with details of authorised Dainese D-air® Street installers who work with authorised stores. These installers have all the necessary expertise to work safely and in full compliance with legislative requirements when fitting D-air® Street M-kits to your bike or scooter. These authorised installers have been selected and specially trained for such work and can therefore guarantee complete reliability of your D-air® Street system.

The accidents that can happen on the road are very different from the falls we see at race tracks. D-air® Street was specifically designed to protect riders from the type of accidents that happen on the road. Its sophisticated deployment algorithm lets it more quickly detect the conditions of an accident and decide whether or not and how to intervene. If the situation does not justify deployment, the system will not activate so as to avoid wasting money on testing and replacing.

A typical road accident involves an impact between the front of a bike and a stationary or moving object, usually a car. The numerous crash tests performed by Dainese, demonstrated very clearly that an airbag must be deployed within 80 milliseconds of the first impact to provide protection. The only way to know if an airbag is fast enough is to establish the Total Time of Intervention.       

Total Time of Intervention (TTI) = Deployment Time (DT) + Inflation Time (IT) 

Knowing just one of these values (DT or IT) is of no use at all when trying to evaluate the effectiveness of the system being tested and may conceal technological shortcomings. In severe impacts, the D-air® Street system has a Total Time of Intervention of just 45 milliseconds that is well within the 80 milliseconds available.

All the performance characteristics of D-air® Street have been verified and certified by TÜV SÜD, an organisation which has vast technological expertise in the protection and airbag technology system sector. D-air® Street successfully passed the tests set by EN 1621.2 and EN 1621.4. The system also underwent 800 individual tests including reliability tests in hostile weather conditions such as extreme heat or in the presence of strong electromagnetic interference to name but a few. It is very important to stress the results of the safety tests which confirm that even in the case of a deployment that takes place when there has not been an accident, the rider's ability to keep the bike under full control is not affected.

Dainese products are designed, tested and certified to guarantee that the whole item and any fabric/leather components along with the active and passive protection systems protect the wearer as best as humanly possible.

Dainese have carried out hundreds of safety tests on D-air® garments of every size and obtained TÜV Süd approval for the protection provided.

An airbag is only one part of a protection system: the air pressure inside the airbag on deployment varies from 1.25 to 1.74 bar from the Street version to the Racing version depending on the various configuration of the D-air® garments.

"Cold technology" is a gas injection system that offers considerable benefits in terms of inflation speed, volumes attained and product safety in comparison with other previous technologies (Pyrotechnic Inflater / Hybrid Pyrotechnic / Heated Gas) and was therefore adopted by car manufacturers for airbags.

It is known as "cold technology" because the gas to be compressed and injected must be cooled to reach its liquid form: once the airbag is deployed, the gas is allowed to escape and expands to its gaseous state.
