I respectfully disagree.

The parts on those bikes are not very close to being the same as what is shipped on a production ADV, beyond the fact that they move up and down.

Springs carry the load, valving controls the movement. From a valving perspective, they may run a softly setup front end, but they would not run fork springs that cannot carry the weight of the machine and rider.

The 950/990 come with 0.48 kg/mm springs, which are far too soft to effectively support the weight of the machine and rider without excessive sag. 0.48kg/mm are what KTM supplies on a 450 sx-f. A bike which weighs over 200lbs less than a 990. Most tuners agree that spring rates in the range of 0.58 kg/mm to 0.64kg/mm are what the ADV needs for average use. Bikes used more exclusively off-road can require up to 0.70 kg/mm springs.
