The Verdict
For pure racing performance, the 1962 Norton Manx 30M has the edge thanks to more power (54hp vs 42hp) and a higher top speed and lower weight. The 1956 BSA Gold Star DBD34, however, excels when outright circuit racing performance is the priority. Parts availability is difficult for the 1956 BSA Gold Star DBD34 and very difficult for the 1962 Norton Manx 30M — an important factor for any restoration project.
