Bike looks sick, but as others have stated, I have to disagree with the function on the rear shocks. I know you're probably thinking about the Aprilia and thier lateral monoshock set u, but one, you're shock is much more lateral in an at rest position, which isn't good. Two, you have much longer shocks, again, not helping with what is definately going to be a way to soft spring rate. I bet with you sitting on it, it's sitting practically horizontal giving you binding. It also doen't appear you have the ability to adjust preload and dampening, which with that set up, you'll need to be able to do.
My .02c would be to find a higher point for the front shock mounting point as well as stiffer shocks with full adjustablity on preload and dampening for functionalities sake.
