Could you please elaborate on the "unreal improvement"? I've got 20K on my DR650. Ride it hard on both street and trails. I'm still on the stock suspension with only the rear preload and damping set to near max. I'm 210 lbs and usually carry 10-40 lbs on the rear rack. About the only things I cannot do well with my setup are hitting big bumps (large whoops and jumps) fast, and keeping up with race type dirt bikes in the rough stuff. I'm considering the suspension mods you mention. Will these mods allow for fast riding in the conditions I've mentioned?
