COTTON Motorcycles Parts Manual PDF is above the page.
Cotton have been producing Motorcycles since 1919. TT racing success in the twenties made a reputation for the company, and in its first eleven years the company turned out over 6,000 motorcycles.
1913 Francis Willoughby Cotton, who had completed in motorcycle hill climbs, devise a straight-tubed triangulated frame that gave excellent handling.
1914 As a student motor engineer, he applied for a patent for the frame he had designed. He had the frame tested by Levis. Trained as a lawyer, he was able, therefore, to prevent design copy.
1919 The Gloucester-based Cotton firm began production of a 269cc Villiers two-stroke engine driving an Albion gearbox.
1922 Cotton entered three machines for the Junior TT; an unknown young Irishman by the name of Stanley Woods rode his Cotton to an impressive 5th place, despite a number of alarming mishaps during the race, including both machine and rider catching fire during refuelling.
1923 Woods rode again for Cotton and he scored his first of ten TT victories, despite being only 19 years old. Cotton had proved the very good road holding and cornering qualities of his bikes and the make was to win many more races.
From 1922 to 1925, the range was expanded and Cotton machines had many racing successes.
1930 A saddle tank had been added and the range of models remained extensive with engines from Villiers,(Manuals PDF page) Blackburne, JAP and Sturmey-Archer.
1931 Rudge Python joined the range and by now there was something for everyone. This served the company well during the depressed times of the 1930s.
Post WWII. Little had changed since the 1930s and few bikes were built or sold, although Cotton left the triangulated frame principle and scored successes in moto-cross and road racing. Girder forks were still being used - even as late as 1952.
1953 The company was restructured under Elizabeth Cotton as E. Cotton Motor Cycles. They were successful again in racing until Villiers closed and they lost their British engine source.
1954 Pat Onions and Monty Denley now had ownership of the company and they redesigned and changed the two-stroke engine. The first of the new range was the Vulcan, powered by a 197cc Villiers 8E engine in a rigid frame.
1955 A model with a 9E engine was added, along with the Cotanza that used the 242cc British Anzani twin engine and had a pivoted-fork rear suspension.
1956 A Trials model with a 9E engine and a second 322cc Cotanza were added to the list.
1957 Saw the arrival of a Vulcan Twin with a 249cc Villiers engine.
1959 The Vulcan Twin changed its name to Herald and gained a form of rear enclosure as well as a companion in the form of the Messenger with the 324cc Villiers twin engine. All models were fitted with Armstrong leading link forks. The two Cotanza models were dropped.
1960 Scrambles models were introduced, using the 246cc Villiers 33A engine, as well as a sports version of the Herald, the Double Gloucester.
1961 The range expanded with modified engines and new frames. These were the 9E Vulcan Sports, a 246cc Trials wth a 32A engine, a second Scrambler wth a 34A, the road Corsair wih a 31A engine, and the Continental 29cc twin with a new frame and a sporting style.
1962 The range was joined by the Cougar scrambler, with a new frame and a modified 34A engine.
1963 Two new models appeared using the 247cc Villiers Starmaker engine. One was the Cobra (PDF Manuals page), a scrambler, and the other the Telstar, built for road racing.
1964 Fewer models were produced as the emphasis was more on sports and competition, and this set the trend for the next few years. The Continental Sports twin, Starmaker Trials and Cobra Sprecial models were introduced in an attempt to win customers in a declining market. Despite this effort, each year saw fewer models, until there were only three left.
1968 Decline continued and Villiers ceased proprietary engine production, which affected many British firms.
1970 Company moved to Stratton Road, Gloucester
Early 1970s. Kit-form trials bikes were then produced, using the 170cc Minarelli engine. Also produced 3-wheel truck, the Cotton Sturdy.
1974 The kit bike was listed as the Cavalier
1975 Late in the year it was replaced by the Meteor scrambler with a 125cc Minarelli engine.
1976 The Meteor went, but they were able to use a Villiers-type engine made by DMW for a trials model. They later became involved with both CCM and Armstrong.
1978 After several further moves in Gloucester, the firm moved to Bolton.
1979 The Cotton-ECM road racer emerged with a 250cc tandem-twin two-stroke Rotax engine (made by Bombardier-Rotax GmbH (Fault Codes page)) in a mono-shock frame with Marzocchi forks, Brembo brakes and Dymag wheels. With it came motocross models in 125cc, 250cc and 400cc sizes, but these quickly became Armstong models, and thus brought the Cotton name to an end.
1980 The company closed.
1991 Fluff Brown revived the Cotton name and since then replicas of the 1960s bikes have been built by AJS Motorcycles of Hampshire. This company was formed when FB-AJS took on the AJS (Manuals page) line in 1974, and the nostalgia boom of the 1990s saw continued demand for these machines.
