The SW Motech 30 mm are like a spacer that sits on the pre existing bar clamps with new tops and longer bolts. A very easy 10-15min job to fit. Unbolt, lift bars out the way, put spacers in, put caps over the top, jiggle the bar around a bit. Put in the new bolts and you're done.
This is for the xt1200 but the same idea.
