I experienced the usual wrist ache when I first got my SV too, I think it was cured by several factors:
Adjusting the levers, play with a few angles, it isn't always obvious what is "right" for you
Riding more relaxed, I found when I was tense it got worse as I was gripping the bars (I still notice it in cold weather now as I've got heated grips so I grip them for heat and feel my wrist ache again)
Acclimatisation, you get used to that being the normal position, it just takes a little getting used to.
