When comparing motorcycle airbags, it is easy to focus on how fast they trigger and overlook volume, but the amount of gas an airbag holds plays a direct role in how well it can absorb an impact.
Why volume matters
A larger volume of gas allows the airbag to maintain a more even pressure at the moment of impact, which helps it absorb the force of a fall rather than transferring it straight through to the rider. As a general rule, a larger protective volume supports better impact absorption, though the trigger speed and any rigid back protector fitted also play an important part in overall protection.
Helite's protective volume range
Across Helite's motorcycle range, protective volume runs from 17 to 28 litres depending on the model and size. The Double Turtle sits at the top of that range, at 28 litres. Cartridge size is matched to the airbag and garment size, since a smaller rider needs a different volume of protection to a larger one. We cover cartridge sizing in full in a dedicated guide.
What the coverage extends to
Helite airbags are shaped to cover the spine, neck, chest, kidneys, abdomen, hips and sacrum. Coverage also extends up around the neck, which helps stabilise the area between the airbag and the helmet during a fall.
How Turtle Technology changes the picture
Volume is only part of the story. Turtle Technology pairs the airbag with a rigid back protector positioned over the top of it, which spreads the force of an impact across a wider area rather than concentrating it on one point. Independent testing by the CRITT laboratory, cited on Helite's own technologies page, found this design cushions impact around four times more effectively than a standard airbag of the same size and shape.

Frequently asked questions
Does a bigger airbag automatically mean better protection?
Generally, yes, a larger volume supports better impact absorption. That said, trigger speed and design details such as Turtle Technology's rigid back protector also make a real difference, so volume is one factor among several rather than the whole picture.
Why do airbags come in different cartridge sizes?
Because riders vary in size, Helite matches the cartridge to the airbag and garment size, so the volume of protection suits the person wearing it.
What parts of the body does the coverage extend to?
The spine, neck, chest, kidneys, abdomen, hips and sacrum, with additional neck coverage to help stabilise the area between the airbag and your helmet.
Does Turtle Technology change how the airbag's volume protects me?
Yes. Pairing the airbag's volume with a rigid back protector spreads the impact force over a wider area instead of one point, which independent testing has linked to a meaningful improvement in force distribution over a standard airbag.
