My brother and I were talking and he asked me this question and I don't know the answer. Does anyone know if I can get a triple rate spring for my stock YFZ shocks? If so how much would it be and is there an advantage to it? Especially if I were to revalve my shocks at the same time? What's the advantage of triple/quad rate springs and why don't they use them on motorcycles? I weigh about 160 lbs. with my gear on and the shocks beat me up and I have my sag set and everything, it's about as light as they can go. Would it be worth it to do all that?
