This last ride in the Sierras, one of our riders had an awkward bike drop which resulted in a soft fall and inflation of the Helite airbag. Tiny scratches to the RT and a rush by the other riders to upright the bike and unsnap the airbag from crushing the rider.
The Alpinestar computer determines whether the crash warrants inflation, and the type of inflation. For the race version, which only inflates one argon canister in a crash, the rep at the motorcycle show said bone breaks went to zero. The street version inflates both argon canisters in deployment. I suspect this is the case because the street version covers much more body area than the race version.
The Alpinestars system is heavy. Lift the jacket and you are getting a workout. Once on though, it weighs nothing.
After a crash:
Helite: Change out the single CO2 cartridge and you are good to go.
Alpinestars: Send the whole jacket to California to get updated software, new argon canisters, and complete checkout.
