Message: [QUOTE="jaguar, post: 590736, member: 19340"] I've replaced the front fork springs for stronger ones (but not the rear) and was notating the free and race sag front and rear. Race sag (sag with rider weight) for the front is 43mm and rear is 85mm. (25.6mm=1"). Quite unbalanced but then I thought it may be to my advantage on the MX course since of course lowering the rear adds more fork angle. I think most MX bikes are around 30 degrees but my KDX is listed at 27 degrees (probably for tight turning in the woods). So with some rough calculations I figured that for every extra 1 inch rear sag there is 1.66 degrees more fork angle. Since my rear race sag is 1.6 inches more than the front then that means there's 2.65 degrees more making the total 29.65 which is closer to what most MX bikes have. If I'm wrong about 30 degrees for MX bikes then please let me know. I went looking thru my magazines for specs but couldn't find the fork angle on any tested bike. UPDATE: I found a web site with some specs for 2003 bikes. Here's their fork angles: KX125 27.5 KX250 27 CR125 29.5 CR250 26.7 KTM (all) 27. So only the Honda 125 has near 30 degrees. years back when the mags used to show all the specs I remember most of them being close to 30. I'll probably try it as is on the MX track and then reduce the rear race sag and try it again. The theory is that more angle gives more straight line stability (going fast) and less tight turning capability. [/QUOTE]
