```
Horsepower = (Cubic Centimeters / 1,250) * (RPM / 5,252)
```
Where:
- Cubic Centimeters (CC): The displacement of the engine in cubic centimeters
- RPM: The revolutions per minute of the engine
In this case, the displacement is 206cc, so we can calculate the horsepower as follows:
```
Horsepower = (206 / 1,250) * (5,252 / 5,252) = 6.5
```
Therefore, 206cc is approximately 6.5 horsepower.
