DMB
DMB were motorcycles produced circa 1927, in Birmingham.
The company had previously built bicycles and went on to produce lightweights that were typical of the period. They used 247cc and 343cc Villiers engines set in a diamond frame, with chain-cum-belt drive. As there were so many other similar machines on the market at the time, DMB were short lived.
