An Australian study has found that helmet-mounted accessories do not increase the risk of head or neck injuries.  Transport for New South Wales (TfNSW) Center for Road Safety conducted testing to determine whether helmet-mounted devices constitute an additional danger to riders.

Noting that conventional impact (drop) tests contained in British Standard (BS) 6658:1985 “Specification for protective helmets for vehicle users” does not replicate a rider’s head and neck injury risk in a real-world motorcycle crash, the agency developed its own test parameters.

The agency used an “oblique test method” in the study, where the tested helmets impact a moving striker plate.  TfNSW said that this kind of test is a more “biofidelic” (human-like) test.  Accordingly, they conducted 220 impact tests in this way with various helmets and attachments.

Areas tested

The helmet areas struck included:

  • Front lateral
  • Helmet rim lateral
  • Rear lateral
  • Crown

Items tested

The six helmet models tested included:

  • Airoh Storm
  • RJays Apex
  • Roof Cooper
  • Scorpion Boulevard
  • Scorpion Vintage
  • Shark Ridill

Finally, the devices tested included:

  • Drift Ghost 4K
  • Go-Pro camera
  • NuViz heads up display unit (mounted on chin bar)
  • Scala communication unit
  • Sena Bluetooth communication unit


Once testing was completed, it was determined:

“…that attaching a camera or communication device to a motorcycle helmet does not, on average, increase the risk of head or neck injury to the person wearing the helmet, in a crash.” 

While TfNSW did see some adverse results, they found that:

“…there were no discernible patterns to these and the overall injury risk in these scenarios was marginal.”

Ultimately the study concluded:

“Based on the findings, that devices appropriately attached to helmets do not significantly increase the
risk of head or neck injury, Transport for NSW instituted a policy change that allows for devices to be
attached to helmets, so long as the attachments do not compromise the structure and integrity of the
