Bete de Vitesse
The Bête de Vitesse (speed beast ) was a racing tricycle by the French manufacturer Buchet that was built in 1903. Similar to the De Dion Bouton three-wheeler, the vehicle had the engine on the rear axle.
It was powered by the 4,245 cm³ air-cooled parallel two-cylinder engine manufactured by Buchet . The engine had a bore of 130 mm, a stroke of 160 mm and is said to have delivered an output of 32 hp at a speed of 1200 revolutions per minute. It is still considered to be the largest engine of its kind.
The performance development of the combustion engine was limited at the turn of the century by the technical possibilities of mixture formation and ignition. Around 1904, the surface carburetor was replaced by the float carburetor and the low-voltage magneto ignition by the high-voltage magneto ignition from Robert Bosch . Until then, "a lot (cubic capacity) helps a lot."
1904-05 was probably a Buchet engine, among other parallel twins in pacemaker race in the pacemaker machine from Franz Hofmann used.
