Well I checked the parts diagrams for both bikes, and the part numbers are quite different. Both the springs and the cartridges are different as well as the inner fork tube. However the seals, bushing, and cap are the same.
My guess is the differences have to do with handling specifically for the 21" wheel. Which would mean that this kit would handle better than a CC with the wheel and 1.5" lowering link. In theory.
