Quadrant Popular 500cc 1925

Quadrant was one of the earliest British motorcycle manufacturers, established in Birmingham in 1901. Famous for their big singles, Quadrant pioneered many innovations that proved important for motorcycle development but struggled after the First World War and the company was wound up in 1928.

The first model, equipped with the very popular Minerva clip-on engine, appeared in 1901.
A few years later  a famous long-distance rider by the name of Tom Silver was contracted by the company.
He attracted a lot of publicity in the years to come by getting excellent results in long distance events and in 1907 he became  managing director of the firm.
Although several types of engines were experimented with, Quadrants were best known for their big singles; in the early twenties even a 780 cc single with unit-construction gearbox was marketed.

This 1926 side valve Model has a Quadrant own made 490cc single Engine(bore 79mm, stroke 100mm),with large air cooled radiators, detachable cylinderhead, large interchangeable valves. Adjustable tappits, gear driven Magneto.
