It is normally designed and so larger face shims are installed to lay flat onto the valve body face. The quantity of large dia face shims is a tuning setup, palcing a smaller dia between the larger diameters creates a transition or crossover. This done to further tune certain aspect of the valving. Many times you see these transitions in off road application but they could be used in any application as the tuner sees fit. The reason for the transition or 2 stage type valving is to normally allow for softer initial compliance that ramps the valving firmer once the 2nd portion of the shims are applied. Appologies if this is overgeneric, I'm not sure if you are specifically heading somewhere with this or just needing some info.
Converting the MV to a checkplate will place virtually 100% of the compresion fluid control into the BV. I say virtually 100% because not all flow is through the shims, depending on setup, a portion of fluid flows through the freebleed/clicker.
Yes it is possible your KTM was delivered with a single stage type shim format.
