just had some hagon springs fitted to forks on my 99 fazer. does any one know how much the forks should sag?? with no rider they settle to about 25mm from fully extended with me on board they use about 35-38mm measured with a zip tie on forks.
As a rough guide, with the weight of you on board the bike they should sag no more than a third of the overall travel.
Full FZS front fork travel is 120mm so as you have under 40mm of travel, they sound about right for a comfortable ride
they do move more than the originals thanks for the reply has reassured me a bit.
