As Camcorderbuyer expertly suggests, all camera mounting systems are the same, all motorcycles vibrate the same and there are no variables to consider here.

Following Camcorderbuyer's advice, you can tape a PC55 to your head or connect your helmetcam to it through the docking station since the camera itself lacks an A/V-in port. Very cool.

You do NOT want to place pretty much any camcorder with an A/V-in port and LANC port (for wired remote control) in a padded bag safe from both the elements and vibration while having it wired to your helmetcam or mounted bulletcam.
