The Victoria record machine (1951) was a racing motorcycle from the Victoria works in Nuremberg , which was only built to achieve a speed record.
Development and technology
In 1948, after World War II , the Victoria FM-38 engine began production as one of the first auxiliary engines. This auxiliary motor newly developed by Albert Roder with an output of 0.8 HP (588 W) at 3500 rpm had a bore of 35 mm and a stroke of 40 mm. The cubic capacity was chosen in such a way that it did not exceed a capacity limitation of new engines to be produced by the Allies - initially the upper limit was 40 cm³. The auxiliary motor, which was designed as an add-on motor to a bicycle, was used very successfully on the Vicky moped models .
In order to increase sales of the two-speed add-on engine, Victoria built a racing engine for record attempts. The driver was Georg Dotteroft, who played a key role in tuning the record engine: transfer ports, pistons, carburettors and compression were changed so that the engine performed more than twice as much as in series production.
Record run
On April 12, 1951, Dotter Weich rode a disguised bicycle with an auxiliary engine on the Munich - Ingolstadt motorway at 74 km / h, in the opposite direction at 84 km / h, with an average of 79 km / h, a world record in the class up to 50 cc was achieved. Yolk soft tried different clothes and positions before the record attempts - his leather suit was too heavy, sitting was out of the question from the start; in the end he set the record lying down in an Igelit suit. The record motorcycle is now in the German Bicycle Museum in Neckarsulm .
