Scale and New Scale

The Scale 350 c.c. Two-stroke.

A Two-speed Lightweight with Automatic Lubrication.

THE Scale two-stroke motor cycles enjoyed quite a good reputation for sturdy construction before war requirements compelled their temporary withdrawal from public notice. The makers, Roberts and Hibbs, Bank Street Works, Droylesden, Manchester, are now re-entering the field with a much improved model embodying the “Precision” 350 c.c. two-stroke engine which we described in our issue of May 29th last. This engine, as our readers are no doubt aware, is automatically lubricated from the sump, the magneto driving chain being used as the oil distributing agent. Two types are being made, a plain two-speed model and a two-speed, clutch and kick-start model, listed at 65 and 70 guineas respectively. Frame construction is on standard lines, and special attention has been paid to securing comfort for the rider by incorporating Brampton Bifiex forks and an XL’All saddle. The tank tapers slightly to the rear, and has a large petrol capacity, since all the oil is carried the engine. 26 x 2 1/4 in. tyres are fitted and T.B. magneto and Amac carburettor complete the specification. The general appearance of the machine is very good, being finished in deep crimson, black and gold with grey panelled tank.

Grace’s Guide:

Scale and New Scale were motorcycles produced from 1920 to 1925, by Henry John Scale

Scale:

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. These were known as Scale models.

1910 By now Harry J. Scale had entered the TT race with a 3.5hp ohv JAP model. He had to retire from race.

WWI. Production stopped for the duration of the war.

Post-WWI. Production restarted with a lightweight fitted with a 348cc Precision two-stroke engine. Production was initially through Roberts and Hibbs.

1920 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.

New Scale:

New Scale motorcycles were built 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 more season before calling it a day.
