Description
Deronzière Autocyclette ca. 1907 282 cc a.i.v. frame#767 engine#494
Deronziere motorcycles were produced in Lyon between 1903 and 1914.
Besides their own power units Peugeot or Zedel engines were used.
This fine example is equipped with the own brand engine. It has an automatic inlet valve and mechanically operated exhaust valve as was common with many French machines at the time.
A special feature is the ignition system, that works with a make and break system in the cylinder head instead of the usual points in the magneto.
There is a spark plug in the cylinder head, but that only has a central electrode.
This little machine has been an exhibit in the National Motor Museum Collection at Beaulieu .
It was purchased by Lord Montague in Paris in October 1958 and restored for the princely sum of £ 36/12/6 as is shown by correspondence to Graham Walker, the Museum motor cycle section curator at the time.
