Doesn't work differently, you use it differently. Are you suggesting that track and road suspension should be set up exactly the same?

Roads are not as smooth as tracks and, generally, you don't push as hard; You may or may not have a pillion on board or luggage. The sites where you can calculate your spring rate give stiffer springs for racing than fast road than touring. I understood that progressive springs were intended to give a compromise between comfort on normal surfaces and stiffness for when you are pushing on.
