The inflation systems you mention have been referred to as Motorcyclist airbags. Designed to minimize injuries to torso/vital organs and neck in the event of an unintended separation from the bike. There are at least a couple companies whom have developed them. Dianese being one of them. Revzilla has talked about them in the past...at least two years ago. They are quite costly. But, if it saves your life, then how do you put a price on it...
