I have...
Used 08 kx450f front end. Emig racing stem. And made my own steering stop.
Easy as pie
is it worth it?
To me it is. I love the old geometry for desert. Hate the new stuff for it. But love the suspension
I havnt ridden it yet with the new forks. Need to get them revalved/sprung.
But the differance to quote BDI "Like atari vs x-box"
