I think the word "kw" means "kilowatt".
To convert kilowatts (kW) to horsepower, you can use the conversion factor that 1 kW is approximately equal to 1.34 horsepower. This means if a motorbike has 20 kW, it would be roughly equivalent to around 26.8 horsepower.

87hp is approximately 64.9kW
624cc
Cant tell for sure. A good engine will have a small cc for its KW, while a crap one will require more cc. CC relates to the size of the engine, while kw refers to the power. Id say a 125 at a guess
If you mean cc as in from a motorbike it stands for centimetres cubed. It is a unit of Volume. 1 cc = 1 ml
No don't think so it goes by the cc. not what you do to it.

16 for a 50cc, 17 for a 125cc - 250cc, 21 for any cc
40 cc is about as high as you can operate without requiring a specific motorbike license in many places. It translates to travel at about twenty-five to thirty MPH.
