History and development of the class

The relative low cost and increasing availability of 50 cc motorcycles in the post-war period, spawned a number of club road racing events for this size of machine in the early 1950s. Motorcycle sport is a broad field that encompasses all Sporting aspects of Motorcycling. The 1950s Decade refers to the years of 1950 to 1959 inclusive With the earliest events being held in Italy[1] and in the UK. [2] The potential of this class for providing entertaining but affordable racing was soon recognised with several national championships and in 1961 the FIM introduced The Coupe d' Europe, a series of international events for 50 cc machines, each with a minimum duration and run to established Grand Prix rules and regulations. [3] The series attracted a variety of entries, but the dominating force were the work’s Kreidler team bikes. Kreidler is a German manufacturer of small motorcycles and mopeds based in Kornwestheim, between Ludwigsburg and Stuttgart. Based on a standard Kreidler Florett road bike, their single cylinder Kreidler Renn-Florett’s featured lightweight frames, a special cylinder head and barrel, twin 16 mm Bing carburettors feeding the engine through rotary valves and improved suspension and brakes. A cylinder is the central working part of a Reciprocating engine, the space in which a Piston travels In an Internal combustion engine, the cylinder head sits atop the cylinders and consists of a platform containing part of the Combustion chamber and the A carburetor (North American spelling or carburettor ( Commonwealth spelling) is a device that blends air and Fuel for an Internal A rotary valve is a type of Valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes By the end of the season, with the addition of rudimentary streamlining and the increase of carburettor size to 17 mm, the 9 hp four-speed two-stroke bikes could top over 85 mph. The two-stroke Internal combustion engine differs from the more common Four-stroke engine by completing the same four processes (intake compression combustion exhaust [4]

As well as the works entries of existing European manufacturers like Kreidler and Tomos, this development also attracted entries from Japanese manufacturers with both Honda and Suzuki entering full work’s teams.

The Kreidlers were now fitted with three speed overdrives controlled from the twistgrip, which coupled to the standard four-speed gearbox gave twelve gears to help keep the engines at maximum power. A manual transmission (also known as a stick shift or just 'stick' 'straight drive' or standard transmission) is a type of transmission used in Engine development also increased power to 10 hp at 11,000 rpm. The Kreidlers development would be hampered however by the factory's insistence that the race bikes remained fundamentally based upon their standard road machines. [5] Suzuki and Honda knew no such limitations.

Honda’s commitment to four-stroke engines dated back to 1951 with the launch of its Dream E-Type[6] prior to this all Honda’s bikes were two-strokes. Today Internal combustion engines in cars, Trucks motorcycles aircraft construction machinery and many others most commonly use a four-stroke cycle. The change and long-term commitment to the more sophisticated four-stroke technology came either directly from founder Soichiro Honda[6] or indirectly due to pressure from managing director Takeo Fujisawa, who was said to be appalled by the noise and smoke that two-stroke engines produced and the additional hassle that Honda customers faced by having to mix oil with their fuel. [7] Honda began their first 50 cc GP season with the RC110, announced at the Japanese Motor Show in 1961. Powered by a single cylinder, four-valve engine, and with gear driven double overhead cams, giving about 9 hp at 14,000 rpm. It was introduced with a five-speed gearbox, but by the time of the opening GP in Spain, the bikes were upgraded to six gears. Even so they were badly outperformed. Rider Tommy Robb suggested that more gears might be the answer and was amazed to find a week later at the French GP that the gearbox had been expanded to eight speeds. Tommy Robb ( October 14, 1934) is a former Grand Prix Motorcycle road racer from Northern Ireland. This still wasn’t enough to compensate for the machines relative lack of power and three weeks later at the Isle of Man TT, nine gears were fitted and the rev limit increased to 17,000 rpm with output now up to around 10 hp. 1962 Isle of Man Lightweight TT 125cc final standings 3 Laps (113 [8] Sometime during the season, the machines designation was changed to RC111, but Honda’s records are unclear as to what precise change in the development this signified or when it was used. [9]

In contrast, the Suzuki team were committed to two-stroke technology and their single cylinder RM62 machine featured rotary valve induction and an 8-speed transmission and produced about 10 hp at 12,000 rpm. Ernst Degner who had defected from the East German MZ team to Suzuki the previous year, bought with him the secrets of MZ’s two-stroke tuning success which undoubtedly helped him and the Suzuki team to secure the inaugural 50 cc World Championship. Ernst Degner (born Ernst Eugen Wotzlawek on 22 September 1931 in Gleiwitz, Upper Silesia, Germany - died 10 September 1983 in Arona MZ Motorrad- und Zweiradwerk GmbH is a Motorcycle manufacturer located in Zschopau, Germany.

The Japanese withdraw

After the withdrawal of Japanese firms from the 50 cc category at the end of 1968, cost-saving technological restrictions were introduced, the Spanish rider Angel Nieto came to the fore, and between 1969 and 1976, won the championship six times.

Motorcycle sport is a broad field that encompasses all Sporting aspects of Motorcycling. By the end of the season both riders were tied with equal points, an equal number of wins and an equal number of second place finishes and the championship winner was determined by adding together and comparing the times for the six races in which the pair had been placed. Nieto was calculated to have won the title by 21½ seconds from his rival. The second ( SI symbol s) sometimes abbreviated sec, is the name of a unit of Time, and is the International System of Units
