BSA D175 BANTAM BUSHMAN, 1969
The most desired Bantam of all and the epitome of BSA Bantam engineering.

The 1969 model is the last Bushman and the best performing Bantam featuring:
new design cylinder head with central mounted spark plug to facilitate quicker and more accurate timing
re-engineered stronger crankcases
10:1 piston compression ratio
13 bhp (previous D14 models had 10bhp)
heavy duty front forks with hydrolic damping and gaitors
larger diameter exhaust port with improved gas flow
exposed rear springs
Large Amal 626 concentric carb
BSA Bantams span from 1948 to 1971 and were used for commuting, racing and trials. Probably the most succesful British motorcycle ever built in terms of numbers but the design was actualy based on the German DKW RT125. After the war companies including Harley Davidson, Russian Voskhod, Japanese Yamaha and of course BSA all used the DKW layout. DKW continued to build motorcycles in West Germany but in East Germany the old factory was renamed IFA and then MZ. The RT125 design was also used.
Bantams are still very popular today as many restorers and collectors find them easy to work on and fun to ride.
The Bushman featured here is quite rare. These are not like other Bantams. They are more powerful and modified to suit both on and off road situations without hesitation.
