Abstract: A radar/laser speed detection countermeasure device for use on a motorcycle is disclosed which detects and annunciates radar and/or laser based speed detection devices in use in the immediate physical area for the purposes of speed limit law enforcement. The device consists of a main detector body mounted in an interior cavity of a motorcycle, which is electrically connected to a remote mounted sensing head unit and a remote mounted indication and control panel. Hidden components and interconnecting wiring reduce the chance of theft and preserve the appearance of customized motorcycles.
