Description of Chinese motorcycle existing technology
The BiMoto/Benelli 250 cc 4-stroke-cycle China Motorcycles had a backbone frame made
from stamped sheet metal with a similar partial cradle arrangement. Both designs employed horizontal single-cylinder engines. With such a layout, the axis of the crankshaft is parallel that of the rear wheel, the cylinder is positioned in front of the crankshaft, and the cylinder axis is horizontal, or nearly so. This engine configuration is believed to provide optimal cooling for a single-cylinder air-cooled engine.
