In 1903 and 1904 JAP and Fafnir ( German) engines were employed and by 1905 Triumph’s own engine, designed by Charles Hathaway was in use. Winning the single cylinder class in the 1908 TT races on the Isle of Man gave an enormous boost to sales of Triumph machines. The cubic capacity of the engine grew from 363cc in 1905 till 5 ...
FN 1925ca. “M50” 748cc four cylinder overhead inlet valve frame # 839 engine # 1756B Responding to demands from sidecarists for more power, FN introduces a 748cc, 7hp four – the Type 700 – for 1914. This new engine is a side valve of ‘T’-head layout, with mechanically operated valves and a mechanical oil pump, which drives the three-speed gearbox via a steel, multi-plate clutch.

Indian 1946 Chief 1207 cc side valve V-twin frame # 3463097 engine # CDF3097 B In 1940, 39 years after the company’s founding, Indian went all-in on the skirted fender design, outfitting Scouts, Chief and Fours with the new tin ware. For many, the pre-’50 girder-fork Chiefs offer the best styling. After that date, telescopic forks were fitted, which threw off the aesthetics a bit in many people’s opinion. The 1946 brochure’s opening sentences are surely tempting: ”Drop into the saddle of this ne ...
Matchless 1922 Model H/2 996 cc MAG IOE V-twin frame # 3961 engine # 2C9 ^ No. 60982 The first Matchless motorcycle was made by the Collier brothers in 1899. In 1907 the Isle of man TT races in the single cylinder class were won: after a second place in 1908 victories were gained again in 1909 and 1910, proving that the machines were matchless indeed. After WW I the company designed a model especially suitable as a sidecar machine, the model “H”. Both JAP and MAG engines were used as power sourc ...
Moto Guzzi 1952 “Airone Sport ” 247cc OHV single frame # M22937 engine # N *97467* In 1932 Moto Guzzi had decided to move into the lightweight market. At first this was the 175cc class that enjoyed various advantages in taxation and driving licence regulation, but when these were abolished the public interest in the 175cc class waned and Guzzi decided to increase the displacement of its little P175. At first the step was made to a 232cc machine but in 1937 the PL was introduced with 247cc capaci ...
Douglas 1930 “T 6” 596 cc side valve flat twin frame # YF 515* engine # EQ 113 At the London Olympia Show in November 1929 new Douglas 500 cc and 600 cc side valve models make their appearance. Designed by Freddy Dixon, these are undoubtedly the most silent and flexible motorcycles available at this time. The whole design concept is bristling with new ideas: these are the “Dixon Douglas” models, with which his name will forever be linked. For the first time a dry sump lubrication system is emplo ...
AJS 1927 Model H1 799 cc side valve v-twin frame & engine # H 60440 The four Stevens brothers had been in motorcycle manufacturing since the final years of the 19th century, but only in 1911 their first complete “AJS” motorcycle, a 298 cc two speeder, was marketed. Their first V-twin Model D with a cubic capacity of 632 cc was introduced in 1912 and was a very successful model, especially for sidecar use. At the 1919 Olympia Show a redesigned 748 cc model D was introduced. Its features included ...
Nimbus 1952 746 cc OHC four in line frame # 10599 engine # 8891 In April 1934 the “Nimbus II” was brought out. The flat steel strip frame was a feature in common with the earlier “stove pipe”, but most other features were totally new: the top half of the crankcase was cast in one piece with the ribbed air cooled cylinder block. The iron cylinder head sported an overhead camshaft. The crankshaft drove the overhead camshaft through the upright mounted dynamo via sets of bevel gears. Its distinctiv ...
Matchless 1996 “G50” 496cc OHC Tom Kirby tribute racer frame # MRD 93044 engine # RVB The Matchless G50 was a racing bike made by Associated Motorcycles (AMC) at the former Matchless works in London.

The G50 was immediately popular, and while slightly less sophisticated than its Norton rival, it was nonetheless 30lb l ...
NSU 1957 251 OSB “Supermax” 247 cc OHC frame # 3229907 engine # 1836241 Production at NSU was resumed already in May 1945. The company had been lucky that only part of the production facilities had been damaged and the American occupiers immediately consigned the works as a repair facility for US army vehicles. At first bicycles and Kettenkrad off-road vehicles were produced and from the summer of 1947 the pre-war 125 ZDB and 251 OSL models left the factory again. Chief designer became Albert Ro ...

Saroléa 1926 494 cc OHV “23 M Super Sport” frame# 30060 engine# 30060 The firm was established in 1850 at Herstal (Liege) as an arms factory by Joseph Saroléa. In 1892 the production of bicycles was started. Joseph died in 1894 and under the management of his sons the company grew bigger and bigger.

BSA 1953ca A7 “TRIBSA” 750 cc vertical twin with Triumph engine frame # BA7S 5378 engine # 6T 46984 In 1937 Triumph had launched its Speed Twin which became a great success. BSA couldn’t stay behind so the company started to develop a vertical twin in the years before the war. This model was to make its appearance in 1940 but by that time BSA got very much involved in the war effort and the launch of new models was postponed. In September 1946 the new twin became available as the A7; it was to b ...

BMW 1951 R25 245 cc OHV single frame # 235723 engine # 239114 Built to the same exemplary standards as the Bavarian company’s famous flat-twins, the single-cylinder BMW first appears in 1925 as the 247 cc R39. Throughout the twenties and thirties singles are brought out in various capacities, ranging from 198 cc to 398 cc. For a number of years after the war Allied restrictions prevent German companies to produce machines of greater capacity than 250cc, so BMW’s first postwar model is a 247 cc s ...
BMW 1961 R 50S 494 cc transverse OHV twin frame & engine # 564812 Bayerische Motoren-Werke is known in English as the Bavarian Motor Works, or more simply as BMW. The firm launched its first horizontally opposed twin in 1923 and has stood by this style of engine layout ever since.

These new models had a similar engine and the same shaft-drive as ...
