Demm Dove moped 49cc. Bought in 1973 when I was sixteen for £80. Went all over the place on it, sold it when I got a bigger bike a year later. Im afraid the colour picture isnt so good but it does show the colour scheme. There used to be a bike shop in Manchester that sold Demm Dove tanks as custom tanks for choppers! You wouldnt have got far they only held 9 tenths of a gallon.
