BSA Motorcycles Bantam D175/B175 1969-1971
The D175 (also known as B175) was a minor reworking of the D14/4 but the Sports model was no longer available.
The spark plug sits vertical in the cylinder head, front forks are stronger (as they are from the larger capacity C15), slightly lower compression ratio at 9.5, separate headlight with high-beam warning, exposed rear shock springs, strengthened kickstart shaft, revised fixing on crankshaft compression disc plates. This final model was produced from 1969 to 1971 but remaining stocks were still being sold at least until 1973.
