I will have to side with Dargo, it looks to me like a traditional style loader such as the woods or a Kubota where the torque tube is doing the work and then Kioti boted a big honking cover over the crossover hydro lines. The cover is similar in shape to the old crossmember but does not look to be attached, so the removable cover would be a full width piece of metal. It also appears that the loader arms have some additional beef added in the torque tube area.
The KL120B looks to be a nice improvement. A casual eye might not notice the improvement at all since the approximate shape is maintained from the KL120 which would be a good PR move. As to an upgrade kit to accomplish this - I do not think that will happen. Way too hard.
I'm anxious to see the 130b but the 120b is indication that Kioti is fixing.
