Anyone see BBC inside out last night?They did a piece about the theft of land rover defenders ,2nd most stolen car in the UK, mostly being shipped to Africa. They also mentioned the high end ranger rovers stolen to order.one range rover dealer was showing what he called a magic wand about the size of a mobile phone that emits a tone that changes when it is near the tracker location .Even the factory fitted ones were sniffed out and apparently the thief's can block the signal until they can remove tracker in a secure location .vehicle then shipped abroad, they showed police recovering some range rovers in containers in the UK and in Africa. One small crumb of comfort was that this dealer has come up with a very small tracker that is undetectable, for obvious reasons he would not discuss it in detail but it could be hidden anywhere on the vehicle. Now whether any body would develop something for bikes is another question but shows its technically possible.
