| Hi Andy, glad to hear your getting somewhere with the bike, my spring rate calculator is in the form of a excel document that uses an equation I settled on years ago when building specials.
Into it you put in weight of bike and rider, bikes rear weight bias, shocks available travel and the linkage ratio, plus a couple of fixed values.So far I have not yet plotted out the 916 rocker ratio, what I did earlier is arrived at a value for the rocker ratio by working backwards from my 6.4kg/mm spring and then changed the riders weight to give me a new spring rate.
