How many cc is a 6.75 horse power motor?

The term "cc" or cubic centimeters is used to measure the displacement of an engine, which refers to the volume swept by the pistons in the cylinders. It is not directly related to horsepower. Horsepower is a unit of power that measures the rate at which work is done. The relationship between engine displacement and horsepower is complex and depends on various factors such as engine design, efficiency, and operating conditions.
