Scott Motorcycles

A Brief History of the Marque

The Scott factory in Shipley, Yorkshire was established by Alfred Angus Scott who left the company in 1915 (or 1919 according to other sources). In 1950 the works were moved to Birmingham where they continued to produce fine two-strokes until 1972. Their most famous model, the Flying Squirrel, became something of a legend.

Alfred Scott left the company he had established in 1919 (?) to concentrate on the development of the Scott Sociable tricar. It is thought that the machine, a cross between a sidecar and a three-wheeler, was developed as a machine-gun platform.

The machines were powered by a 578cc water-ccoled Scott two-stroke twin and were capable of some 80kph. They were not a commercial success and production of the tri-cars ended in 1925.

A report on the 1924 Motor Cycle Show reads, in part:

"The 498 c.c. engined Super Squirrel is the machine which ran second in this year's Senior T.T., while the 596 c.c. model of the same type, put up the record lap in the course of the previous year's sidecar race. Both models have the same general specification, the engines having water cooled heads, straight-through induction pipes, and die-cast aluminium pistons. The smaller machine is recommended for fast solo work : the larger is suitable either for that purpose or for combination work. The other model Scott which will be of interest to our readers is the ordinary Squirrel model, which has an engine of 486 c.c. The prices are : 498 c.c. Super Squirrel, 70 guineas ; 596 c.c. Super Squirrel, 73 guineas, and ordinary Squirrel; 63 guineas.

Borgo Pistons

Alloy Pistons

Aluminium pistons first appeared before the Great War in engines by W.O. Bentley (UK) and Borgo (IT).


The Scott Motor Cycle Co., Ltd., Saltaire, Shipley, Yorks.

Extract from a report on the 1926 Olympia Show:

"True to their recent policy, the Scott Motor-cycle Company are marketing their latest I.O.M. model, embodying the lessons of the 1926 T.T. This very interesting machine has the usual Flying Squirrel type of engine with high compression aluminium pistons and water cooled cylinder heads ; the carburettor, however, is now bolted directly on to the crankcase, as on the T.T. machines. The three-speed gear box is fitted, and the new type forks and duplex triangulated frame with detachable tank and top tube.

The engine is lubricated by a mechanical pump driven from the magneto shaft. The price with the 498 c.c. engine is 89 guineas."

Scott 3S 1939
As far as I know the Squirrel used pistons with deflectors. I would like to know if the 3s engine of the late 30s still used pistons with deflectors because the german DKW car engine used flat pistons and angled admission ports...

Where is it now?
Scott 2sp Super Squirrel
My late father had a motorcycle business pre 1939 in 1946 he put together a 1924 engine and a 1930 frame to make the above machine it was registered in 1946 and given the reg No HLR675 it was subject of an article in either the Motor Cycle or Motor Cycling magazine at that time.

I stripped it and had it rechromed and stove enamelled during the 1960's. It was sold by my father just before his death in the late 70's. I would dearly love to see this bike again and possibly buy it. Any information would be gratefully received
