My KZ1 is coming along now, and thanks to (julien) I now know what calipers are date right, I just need to make my mind up on calipers. I have a set of 890's already, but seems all the reviews I can find seem to have the KZ1 fitted with either 900'e or 1000's. So. Does it really matter? I know the 890's don't look as lush, also is there any real difference between the 900/1000 calipers? HELP!
