So, first off sorry for the late response. But essentially the best way to explain that is it allows a great deal more articulation in the front of the machine keeping the wheels on the ground longer. Sway bars are amazing at higher speeds and for body stability. But for intricate / difficult trails or rocks most riders have quick disconnects for the sway bars or have them removed completely, like our blue XP1K, We have no sway bars on it at all. Hope this helps!
