the B175 Bushman from 1969 - 71. There are various air filters fitted to the Bushman models but all were mounted remotely from the carburettor behind the side panels where the battery was on road Bantams, the Bushman models had direct lighting so dispensed with the battery. Most featured sump guard plates and the engine mounts are raised slightly to give the engine cases better clearance from rocks etc. Even by the mid 1970s the Bushman models were sought after by collectors and they are even more so today an amazing 49 years after BSA produced the last ones in 1971. D18 BSA engineers were working on an upgrade to the Bantam, the D18, before financial troubles in 1971 resulted in a drastic reduction of the model range. The D18 was intended to be an interim model before the introduction of a new range of two-strokes that were in development. The D18 used an alloy barrel and a new head with a central spark plugs. A prototype was built before the project was cancelled.
