2006 kx250f - rider wieght 130 lbs-- I am going to buy front springs and rear shock spring. I looked it up on race tech for the wieghts of the springs Front= stock 0.460 kg/mm motocross - 0.408 kg/mm supercross - 0.428 kg/mm arenacross - 0.418 kg/mm Rear= stock 5.0 kg/mm motocross - 4.76 kg/mm supercross - 4.96 kg/mm I have 2 questions. 1 is I should probably go with the motocross setup becuase I ride on tight stadium type tracks 60% of the time but they are not as technical as a real professional supercross track, but I do ride on motocross tracks the other 40% of the time do you think this is the right thing to do? The stock wieght fork oil is 5w correct? Also, for the rear shock spring.... well its titanium, and putting in a non titanium spring is a downgrade so, where can i get a softer titanium spring at? or should i just keep the rear spring stock. I set the sag on the bike, it dropped 1.25 inches stock when i sat on it LOL. so I backed the collars off and set it to have 4 inches or 100-105 mm's. WOW that made a huge friggen difference in handling I gained like 5-10 % more speed around the track i didnt realize how much it would help So it is set up and seems to feel nice, would the rear spring really help?
