Sit mannequin

So, i'm working on a motorcycle, and I need a custom sit pose for it. I made one in poser, got it working but I realized that the leg portions of it are not working at all. I figured out that since the movement of my legs was designed with the base pose a standing pose (everything works perfectly when I preview from standing position), the legs would not or can not move like I made them from a sitting pose (if I preview from sitting position everything is all wierd). Anyone know of a sit mannequin I can use as a base? or, is there a workaround for this? Any help would be most appreciated!
