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. With the earliest events being held in Italy and in the UK. 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. The series attracted a variety of entries, but the dominating force were the work’s Kreidler team bikes. 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. By the end of the season, with the addition of rudimentary streamlining and the increase of carburettor size to 17 mm, the 9 hp (6.7 kW) four-speed two-stroke bikes could top over 85 mph.

“You treat world history as a mathematician does mathematics, in which nothing but laws and formulas exist, no reality, no good and evil, no time, no yesterday, no tomorrow, nothing but an eternal, shallow, mathematical present.”
—Hermann Hesse (1877–1962)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“We of the sinking middle class ... may sink without further struggles into the working class where we belong, and probably when we get there it will not be so dreadful as we feared, for, after all, we have nothing to lose but our aitches.”
—George Orwell (1903–1950)
