This vintage radio cassette player is the perfect addition to your BMW R80RT or R100RT motorcycle. It was a factory optional extra . It plugs directly into the blue auxiliary plug under the seat of mono models or could be wired to the fuse board in the headlight of older classic models ( just 3 wires , earth,  permanent live , ( clock?) , and switched live  It comes complete with the lockable lid ( no key , but can be swapped with your existing fairing lid lock )  , antenna , remote handlebar contol and speakers , one of the speaker mounting panels is missing , but appears to be still available ( see photo from " partsss.com ' website ) and one of the speaker surrounds has a corner missing , as shown .I fixed it to the plywood sheet so i could try it and the radio works as it should , i do not have any cassette tapes , so cannot test the tape player . Comes with instructions for wiring and operation , plus security code  . Collection is welcomed , from near Preston , Lancashire,  3 minutes from j29 M6 . Any questions please ask,  Dave . The radio is advertised elsewhere so listing may be removed at any time . In photo 7 , the radio box is shown fitted to a bit of fairing , to illustrate how it would look on a bike , the bit of fairing is not part of the listing . The last two photos are how it looks on a bike , showing the position of the speakers .
