Scale were motorcycles produced by Harry J. Scale of Alexandra Park, Manchester, from 1906 to 1920.
- 1906 The construction of machines began and a reputation was soon gained for quality. At first the 6hp Belgian-built Antoine V-twin engine was used, but this then changed to JAP.
- 1910 By now Harry J. Scale had entered the TT with a 3.5hp ohv JAP model. Although he had to retire from that, he had many other competition successes throughout his career, which proved the worthiness of his machines.
- World War I. Production stopped for the duration of the war.
- Post-war. Production restarted with a lightweight fitted with a 348cc Precision two-stroke engine. Finance was obtained through Messrs. Robert and Hibbs and this enabled a move to larger premises and increased production.
- At that point the business was renamed New Scale and continued as such until 1925.
New Scale were motorcycles produced from 1920 to 1925, by Harry Scale in Droylsden, Manchester, who had previously been responsible for the Scale marque.
- 1920 The Scale firm reformed to create New Scale. Various models were produced with Precision two-stroke, Blackburne and oil-cooled Bradshaw singles, all finished in a stylish cerise colour.
- 1921-1923 Various classes of the TT were entered with no success.
- 1924 A fourth place in the Sidecar race at the TT was the best result achieved. They tried out a 147cc Villiers
lightweight with two-speed chain-cum-belt transmission. They also
listed a machine fitted with a 349cc ohc Dart engine. Towards the end
of the year, Harry Scale left the company.
- 1925 With just 349cc Bradshaw and 348cc ohv Blackburne models on offer, the company struggled on for one season before coming to a stop.
