1934 CZ 175cc Lightweight (see text)
Engine no. 103546
At time of cataloguing it had not been possible positively to identify this machine, which is believed to be an early CZ. Founded in Strakonice, Czechoslovakia in September 1919 as an armaments manufacturer, Česká Zbrojovka (CZ) diversified into motorcycle making in the early 1930s and merged with erstwhile rivals Jawa in 1949. Initially very successful, CZ faced a downturn in demand for its products in the late 1920s, diversifying first into bicycle manufacture and then motorcycles a couple of years later. A single-cylinder two-stroke, the machine offered here is unusual in that its engine is mounted in the frame with the crankshaft inline (rather than transversely). This would make perfect sense if it was shaft driven yet final drive is via chain, which involves turning the drive through 90 degrees via a skew gear of some kind. Presumably, the added complication and slight power loss involved was set against the advantage that this arrangement conferred in terms of oil tightness, there being no leak-prone primary drive casing. Consisting of a pressed steel frame and blade-type girder fork, the cycle parts are typical of many European makes of the 1930s. The machine was discovered in its present condition and is offered for restoration.
