Ducati Cucciolo 1950-1951 with a 48 cc Ducati engine. In 1952, with 200,000 Cucciolos already sold, Ducati finally offered its own complete moped based on the successful little pull rod engine, removing the pedals and adding a 3 speed gearbox, creating the model 48 (produced until 1954) and model 55E and 55R. Siata-Ducati Cucciolo 50, 1946. [4]
Motorcycles with a V-twin engine mounted with its crankshaft mounted in line with the frame, e.g. the Honda CX series, are said to have "transverse" engines, [1] [2] while motorcycles with a V-twin mounted with its crankshaft mounted perpendicular to the frame, e.g. most Harley-Davidsons, are said to have "longitudinal" engines.

Whizzer bicycle engines are a line of bicycle engines that were produced in the United States from 1939 to 1965. They were commonly sold as kits to be assembled and attached to a consumer's bicycle thus creating a motorized bicycle.

The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
The model had a pressed steel frame, a shrouded, fan-cooled two-stroke engine with a 3 speed gearbox. [2] The model was updated in 1962 and designated the Champion-III. [4] From 1963 these were imported into the United States by the Rockford company. [11] The Champion was marketed as Bridgestone Super 7 in the US, and was available with an ...
