I weigh 200# and i'm looking to get stiffer springs for my bike. Looking at stock CRF450 springs, they seem to be a close match. They are .47 for the forks and 5.5 for the shock. The MX-tech spring rate generator doesn't have the crf250 in it yet but from using the crf450 as a guidline, the springs that the generator recomends seems to be on the light side. Are the MX-tech springs lighter so that they work better with a re-valve from mx-tech?
