Sep 14, 2006 · I'm looking for the "safe psi range" for both the 2012 YZ125 and 2012 YZ250 compression. I'd like to base my rebuilds on how the compression reads if that's a smart thing to do. Any info/insight is greatly appreciated. Thanks!

Aug 16, 2006 · YZ125 and YZ250 clamps have been 25mm consistently as far as I know. If you are going to use clamps from YZ450f's and YZ250f's, keep in mind that there are different offsets of either 22mm or 25mm that change on different model years of the 250F and the 450f.

Jul 6, 2015 · The 2008-2013 YZ125 or YZ250 clamp works just great. The 2010 - 2011 YZ250F clamp has some minor differences, different features including four bar positions. There are more 250F being parted out... Seems like you're more likely to …
