Single with overhead camshaft.
History
Bianchi of Milan started with bicycles in 1885 and built motorcycles from the beginning of the twentieth century; Tazio Nuvolari raced for the make in the 1920s. After the war Bianchi was one of the big Italian makes, and in 1954 the Tonale 175 arrived.

What to check when buying
- Parts are scarce: above all check that everything is complete, such as the original silencer.
- Cam chain: listen for rattling from the head.
- The electrics are 6 volt with battery and coil: check charging current and wiring.
- Turismo or Sport? Compare the specification with the papers.
- An unfinished restoration can mean years of searching for parts; take that into account.
