Physical Distinctions Between the King Song 500W & 800W

[Jason McNeil]

Besides the additional 2kgs of the weight of the motor, there are some other differences between physical distinctions between the two Wheel.

1. The 800W's control-board is black, while the 500W is blue
2. 500W motor had a serial number next the valve, 800W did not
3. 500W has less resistance to spin (cogging) than the 800W
4. 800W has a much louder whine when powered on
5. Then of course there's the power difference between the two, this is really what it's all about, the 800W feels much more powerful

Hi,

Sorry to bump an old thread. Anybody has a picture of the serial number? See picture attached. My KS-14C order and manual says that my wheel is a 500W, but the box says 800W. I want to do a review, but I'd like to say which wheel I am reviewing.
