The 790-cc double-overhead-cam four-cylinder engine in the 1977 MV Agusta 750S America motorcycle had its roots in a 500-cc racing powerplant. The exhaust system is a combi ...

Ascot-Pullin 1929 “ Sports Utility” 496 cc OHV frame # 184 Engine # AP 184 Cyril Pullin was a rare bird among the many fascinating motorcycle inventors of the early 20th century; while there were many rider-designer-manufacturers during the era, he was in very rare company of men who not only designed, built, and raced motorcycles, but also won an Isle of Man TT race, a distinction he shares only with Howard R. Davies (HRD) and Charlie and Harry Collier (Matchless). Pullin had an extremely inven ...
Phébus 1899 “Berceuse” 2 ¼ HP 269 cc De Dion Bouton quadricycle frame # 1368 engine # 10618 In 1895 De Dion Bouton begins to market motorized tricycles and from the start they are very successful.

Triumph 1973 X-75 Hurricane 740 cc ohv triple frame & engine # TRX75 XH 01920 When, in 1968, the new BSA Rocket 3/Triumph Trident triples were shown to the American BSA-Triumph management, they were not impressed. They knew Honda had the CB750 coming along and they felt the triple’s price of $1800 was too high and that technical details (like vertically split crankcases and pushrod ohv valve train) were far from “cutting edge”. However, they acknowledged that the bike was fast, and a sales team ...
Indian 1923ca PowerPlus “Big Valve” racing style special 998 cc side valve V- twin engine # 71V409 The Indian PowerPlus engine is a design of Charles Gustafson, who had already earned fame as an engine designer at the Reading Standard company. His task was to design a powerful, robust, reliable and production friendly engine to replace the old F-head V-twin design of Oscar Hedstrom. The resulting 61” side valve PowerPlus introduced in 1916 was an immediate success and this model is still one of ...
Indian 1919 “ N-19 ” PowerPlus 998 cc side valve V- twin engine # 82M971 By 1915 the Indian Board starts to have worries about the financial situation of the company, because the IOE engine and Hedstrom-designed carburettor are costly to produce. The inlet-over-exhaust configuration was adopted by most American manufacturers and was basically a good design, but it had one weakness: the inlet valve pushrods and rockers were external to the engine and thus exposed to the elements. This could give ...

Weight of the machine was 65 kg and the fuel consumption was less than 3 litres per 100 km. This light single became a popular seller next to the FN four cylinder model. In ...

The engines are not as good as the company expects so ...

For their new superbike the engineers at Moto Guzzi install the alternator on the crankshaft nose which allows the engine to be fitted lower in a new frame, thus improving the centre of gravity. The new frame is a significant improvement over its forbear and when combined with the revised 5-speed gearbox and large-diameter dr ...

Very soon the quality and practical utility of the invention becomes known even far beyond the Swiss territory. Gradually the engines grow bigger and more powerful, twin ...
Connaught 1921 293cc two stroke single engine # 479 Connaught motorcycles were produced by the Bordesley Engineering Co. of New Bond Street, Birmingham. Their first machine was presented at the 1912 Olympia Show and The Motor Cycle of November 28, 1912 wrote: “This is an interesting little machine, which is shown on the Service Company’s stand, in that the lubrication is effected in a peculiar manner.

Ducati 1974 860 GT Paul Smart Replica 864 cc OHC V-twin frame # 852732 engine # 855384 Designed by the legendary Fabio Taglioni, Ducati’s first road-going v-twin – the 750 GT – arrived in 1971. Lacking the resources of larger rivals from Japan, Ducati made the most of what it already possessed to create one of the all-time great motorcycles of the post-war era. A 90-degree vee, the engine looked like two of the Bologna firm’s bevel-drive overhead-cam singles on a common crankcase (which in essen ...
Honda 1964 Benly CB92 Super Sport 124 cc OHC twin frame # CB 92 2105269 engine # CB92E-2101452 At its introduction this sporty little 125 was surely a revelation to a market used to traditional British machinery. The CB92 Super Sport took its styling and design cues from the larger-displacement C71, C76, C72 and C77 Dream series. The 360 degree overhead cam parallel twin engine generating 15 bhp at a heady 10,500 rpm must have been the most eye opening feature, but it didn’t stop there. Other un ...
Zenith 1919ca “Model D” 5 HP 654cc JAP side valve V-twin combination frame # 6300 engine # 8/81598 EX In pre W.W. 1 days Zenith machines gained many successes; driving force was chief engineer Freddy Barnes, who was responsible for the famous “Gradua” gear. The mechanics of the Gradua gear were a variable engine pulley worked by a handle, with simultaneous correction of the belt length made by sliding the rear wheel backwards or forwards in the fork slots. Its advantage showed itself most effect ...
