SCOTT – year 1909

Manufacturer: Scott Engineering Co., Ltd., Bradford, Anglia

In the early twentieth century, Alfred Scott dealt with the design of a small two-stroke engine with a capacity 130 cm3, which was to serve as an auxiliary power unit for the bicycle. First (two-cylinder) two-stroke engine, suitable for practical use, he managed to perform v 1908 year. The prototype specimen had an air-cooled cylinder and a water-cooled cylinder head. Another engine, which in 1909 of the year began to be produced in series (with two parallel cylinders, forward inclined 45 ° and displacement 333 cm3) he was already all water-cooled. This model made the Scott brand famous all over the world.

The then unprecedented cooling system was not the only original solution for Scott's motorcycle engines. Another design peculiarity was the split crankshaft with the flywheel located in the center, between slightly spaced cylinders. Rolling bearings were mounted in the connecting rods. The two-speed gearbox was driven by a chain. The chain gear also transferred the drive to the rear wheel. The modern open tubular frame was somewhat reminiscent of a modern women's bicycle. Foot shifting already used at that time, became popular only in the early 1930s.

A construction curiosity of Scott's racing motorcycles was the rotating stump, controlling the flow of mixture to the cylinders.

In years 1912 i 1913 Scott vehicles – Twin models - triumphed in the Tourist Trophy races (victories of F.. A. Applebee i H. THE. Wood in the senior class).

The described design solutions were used in Scott motorcycles for almost the entire half century, that is during the company's operation period. However, they were perfect enough, that vehicles of this brand have always taken the leading positions in the group of the best English motorcycles.
