I am so happy. I finally figured out the setup for my YZ 450F. Now I feel faster, smoother, and I am not getting beat to death. Now I can really appreciate the capabilities of the 07 YZ 450F. Here's what I got: Front and rear tire pressure: 8.5 lbs (riding in desert with lots of sand). Rebound - went factory setting front and back Compression - 10 out from hard, front and back Sag - 3.5" Stock Pro Taper bars with Tusk bar riser kit, all spacers installed except thinnest one. I find that I am much faster sitting down. This setup allows that without jarring me when I hit sharp edges. I can get up off the seat very quick, and the bar height really helps to get the bike turned and loft the front end when needed.
