Cylinder head ATHENA for 150cc Ø58mm kit for KAWASAKI KX and YAMAHA YZ 125cc

Here is the replacement cylinder head ATHENA Big Bore 150cc Ø58mm for KAWASAKI KX 125cc from 2003 to 2007 and YAMAHA YZ 125cc from 1997 to 2004. This good quality aluminum cylinder head allows a good combustion of your gas. However, following a strong heat the cylinder head can be warped and therefore not be tight. In this case, rather than to replace the cylinder head, we strongly advise you to change it. Because it is a high compression cylinder head. If you overcompress it again, you risk a malfunction of your engine and especially a breakage of it.
