Man

Seen just after his victory with an average speed of 80 mph, is F. L. Firth.
The original
Norton
company was formed by James Lansdowne Norton (Known as Pa) in
Birmingham
in 1898. In 1902 Norton began building motorcycles with French and Swiss engines. In 1907 a Norton ridden by Rem Fowler won the twin-cylinder class in the first Isle of Man TT race, beginning a sporting tradition that went on until the 1960s – The Isle of Man Senior TT, the most prestigious of events, was won by Nortons ten times between the wars and then every year from 1947 to 1954. The first Norton engines were made in 1908, beginning a line of side-valve single cylinder engines which continued with few changes until the late 1950s. In 1913 the business declined, R.T. Shelley & Co., the main creditors, intervened and saved it. Norton Motors Ltd was formed shortly afterwards under joint directorship of James Norton and Bob Shelley. J.L. Norton died in 1925 aged only 56, but he saw his motorcycles win the Senior and sidecar TTs in 1924.
Designed by Walter Moore, the CamShaft One (CS1) engine appeared in 1927, based closely on the ES2 (pushrod) engine and using many of its parts. On his departure to NSU in 1930, an entirely new
OHC
engine was designed by Arthur Carroll, which was the basis for all later
OHC
and DOHC Norton singles. (
Moore
's move to NSU prompted staff to claim that NSU stood for "Norton Spares Used") That decade spawned the Norton racing legend. Of the nine Isle of Man Senior TTs (500 cc) between 1931 and 1939 Norton won seven. Up to 1934, Norton bought the excellent Sturmey Archer gearboxes and clutches. When Sturmey decided to discontinue production, Norton bought the design rights, and had them made by Burman, a manufacturer of proprietary gearboxes. Nortons also appealed to ordinary motorcyclists who enjoyed the reliability and performance offered by single-cylinder engines with separate gearboxes. The marque withdrew their teams from racing in 1938, but between 1937 and 1945 nearly one quarter (Over 100,000) of all British military motorcycles were Nortons, basically the WD 16H (solo) and WD Big Four outfit (with driven sidecar wheel). After the War, Norton reverted to civilian motorcycle production, gradually increasing the range. A major addition in 1949 was the Dominator, also known as the Model 7, a pushrod 500 cc twin cylinder machine designed by Bert Hopwood. Its chassis was derived from the ES2 single, with telescopic front and plunger rear suspension, and an updated version of the gearbox known as the 'horizontal' box. Post war, Norton struggled to reclaim its pre-WWII racing dominance, since the single cylinder machine was facing fierce competition from the multi-cylinder Italians, and AJS at home. In the 1949 Grand Prix motorcycle racing season, the first year of the world championship, Norton only made fifth place, and AJS won. That was before the Norton Featherbed frame appeared, developed for Norton by the McCandless brothers of
Belfast
in January, 1950, used in the legendary Manx Norton, and raced by riders including Geoff Duke, John Surtees and Derek Minter. Overnight the featherbed frame was the benchmark by which all other frames were judged. Nortons were winners again. Norton also experimented with engine placement, and discovered that moving the engine slightly up/down, forward/back, or even right/left, could deliver a "sweet spot" in terms of handling. In 1951 the Norton Dominator became available in export markets as the Model 88 with the Featherbed frame. Later, as production of this frame increased, it became a regular production model, and was made in variants for other models, including the ohv single cylinder machines. The racing successes were transferred to the street through Cafe racers, some of whom would use the feather bed frame with an engine from another manufacturer to make a hybrid machine with the best of both worlds. The most famous of these were Tritons - Triumph twin engines in a Norton feather-bed frame. Despite, or perhaps because of the racing successes, Norton was in financial difficulty. Reynolds could not make many of the highly desired featherbed frames, and customers lost interest in buying machines with the older frames. In 1953, Norton was sold to Associated Motorcycles (
AMC
), who also owned the brands AJS, Matchless, Francis-Barnett and James. The
Birmingham
factory was closed in 1962 and production was moved to
AMC
's Woolwich factory in south east
London
. Under
AMC
ownership, a much improved version of the Norton gearbox was developed, to be used on all the larger models within the corporation under the AJS, Matchless and Norton banners. Again, the major changes were for improved gear selection. In late 1955 a 600 cc Dominator 99 appeared. The 1946-1953 Long Stroke Manx Norton was 79.6 mm x 100 mm, initially sohc, the dohc engine becoming available to favoured racers in 1949. The Short Stroke model (1953-1962) had bore and stroke of 86 mm x 85.6 mm. It used a dry sump 499 cc single cylinder motor, with two valves operated by bevel drive, shaft driven twin overhead camshafts. Compression ratio was 11:1. It had an Amal GP carburettor, and a Lucas racing magneto. The 1962 500 cc Manx Nortons produced 47 bhp (35 kW) at 6500 rpm, weighed 142 kg (313 lb), and had a top speed of 209 km/h (130 mph).[6] The new price was £440. Manx Nortons also played a significant role in the development of post war car racing. At the end of 1950, the English national 500 cc regulations were adopted as the new Formula 3. The JAP Speedway engine had dominated the category initially but the Manx was capable of producing significantly more power and became the engine of choice. Many complete motorcycles were bought in order to strip the engine for 500 cc car racing, as Nortons would not sell separate engines. Manx rolling chassis were frequently resold, and equipped with Triumph engines. These motorcycles were known as Tritons. In 1960, a new version of the featherbed frame was developed, with the upper frame rails bent inwards to reduce the width between the rider's knees for greater comfort. The move was also to accommodate the shorter rider, as the wide frame made it difficult to reach the ground. This frame was made in-house by
AMC
, and is known as the 'slimline' frame - the earlier frames then became known as the 'wideline'.
