Might I suggest, if you can, get the front wheel off the ground. Move the bars lock to lock and return it to center. If it moves, make sure nothing is binding and pulling the wheel.(cables, wiring, hoses) Check at a 45 degree left and right also, it doesn't take much to bind up.
This is the easiest place to start. From there, a whole host of things could be going on. Fork fluid difference, swing arms, tires, weight, etc.
