Will it fit? Mine is completely sprung/re-valved for me. This is from the two stroke variety. I'm about a '07 WR450F brand new for a low price! However, I like my suspension and I'm not sure I can live without the Rekluse or my plate but I've never been hassled by LEO wherever I ride anyway. Also, this is the same suspension that comes with the YZ450F from the same year. Humor me if you will (or won't). If I can't swap it over then maybe I'll just keep smoking. Also, is this bikes ergos larger than a 250F? I'm 6'2" and 250 lbs and would like some engine braking and a bit more tractor low end.
