I discovered after buying my Aprilia last year that, technology being what it is now, the bike records the maximum speed reached on a ride. It's always a bit of a shock when I see how high this speed can be, but I suppose it's a speed that may have just been touched on for a second. It occurred to me that if I was stopped I could always just reach down and delete it. Then I imagined a situation could happen when, for instance, a car pulled out in front of me and knocked me off the bike leaving me injured. I could have been riding perfectly legally at say 40mph in a 40 zone but the information retrieved says 90mph - it wouldn't look good for me! Let us give thanks for simple bikes like the Commando!Certainly valid FE. Also depends where you are in the world I suppose.
There are states in Aus where actually mounting an external helmet camera is illegal - classed as a helmet modification. In others it’s legal. Bikers have been fined and issued points when riding through one state into another - barking mad!
The police may notice an external mounted camera no doubt. Mine is discrete and internal to the helmet - much more difficult to spot. The footage does cover the clocks though, so would incriminate myself and anybody in front with matching (or greater) speed. It’s easily erased via the app though, or by simply reaching up and ejecting the micro SD card.
Also plenty of discreet camera options for mounting on the bike itself. But the risk of plod accessing them is still there.
Personal choice I suppose, linked to how we each ride and what we value most. I certainly feel better protected having a record of what’s occurring in front of me. Almost never look at it - it just loops (recording over when the card is full).
