Either will work as the Husaberg and KTM upper triple clamps are the same.
IMHO the Scott's damper is superior for a few adjustable reasons. With the Scott's you can adjust the degree of dampened sweep (90, 54,44, or 34 degree's from center) ; two seperate damping circuits High and Low speed, and the little talked about fact that the Scott's dirt bike damper only dampens from the center point out. So that when returning the steering from full left or right to center there is no damping.
However, the street bike damper, which looks the same as the dirt bike dampe,r dampens both ways, center out and back to center. So it's more of a personal preference type of thing.
I have had a Scott's damper since 1999 and have absolutely no problems with it what so ever.
Give the folks at Scott's a call 818-248-bike, I'm sure they can set you up with what you want.
