The shock or the shock spring? The shock can be made to do anything you want it to do. From wondering to full professional racing. Way better than the 1090R 790R the current EXC models and the aftermarket. All pds needs a bit more progression and that is why they benefit from a correct variable rate. This also allows larger range of single up and two up performance. The shock is too firm in initial stroke from the factory and that is a combined valving, spring issue. Traction and compliance suffers. So we open it up initial and slow it down deeper into the stroke.
