摘要

The motorcycle has an engine block that is admitted by using a valve case (11) and valves (12). The case controls adjustments of admission flux and permits an anti-return of gas admitted into a combustion chamber for management of suction of an engine. The valves allow to close the combustion chamber before explosion. Radiators are placed in sides of a steering column for performing a cooling function. The radiators are compartmentalized for constituting a water reservoir and an oil reservoir, where the water reservoir represents 75 percent of volume.
