“When a handful of lovers within the Bristol space conceived the thought of 500cc racing, little did they know the way common the category would change into,” we mused in 1951.
“These machines, powered by a single-cylinder engine, at the moment are placing up terrific performances, and the brand new Kieft has not too long ago taken the lap file at Goodwood, at 84.55mph.”
We rightly foresaw such light-weight and easy automobiles, initially home-built by fun-starved lovers, as the best way ahead by way of post-war austerity and rationing.
We mentioned: “The issue dealing with the constructor was roughly this: to construct a chassis to take the ability unit (the identical twin-OHC Norton [motorcycle] engine as was beforehand fitted in Stirling Moss’s Cooper) that may be lighter than that of different 500cc automobiles however on the similar time extra inflexible, with suspension offering roadholding a minimum of equal to that of its rivals.”
This was achieved utilizing a metal tube chassis with a stiff field centre part, swing-axle rear suspension (with a intelligent cable set-up managing weight switch) and a double-wishbone entrance. The gas tank was within the field, fore of the engine and gearbox, to take care of an excellent weight distribution.
The London-built automotive had nearly no testing earlier than the five hundred Worldwide Trophy at Goodwood, but Moss – who had rushed there from Monza in a single day – overcame “slight bothers” within the first warmth (by which he got here sixth) to complete the ultimate a half-mile up on Alan Brown in his Cooper-Norton.
The little Kieft’s success continued with Don Parker successful the British F3 title in each 1953 and 1954.
